Car battery - seasonal goods, although it is used all year round. When birds sing on the street, and warm oil is splashing inside the engine, then scrolls the crankshaft is easy - even the half-hearted battery is coping with it. But in the cold starter is not easy, and it strives to turn into a purely active resistance that consumes a very long current. As a result, the battery strives to refuse, and the owner will have a campaign to the store.

How to choose a battery

If you do not want to contact the service or assistance to the seller, the selection algorithm should be the next one.

You need to take a battery that is guaranteed to fit into the niche allotted by it, whether it is a motor compartment, a trunk or something else. Agree: stupid to miss a couple of centimeters! At the same time, the polarity is determined: we look at the old battery and we think that it has on the right, and what's left? Of course, that if the car is not European, then the terminals themselves may differ from most familiar - both in form and location.

After that, choose a brand. Here we definitely advise you to follow the list of our winners of recent years and never "peck" for beginners or outsiders. Even if their labels are the most beautiful. Here are some names from those that usually not let us down: Tyumen (Tyumen batteries), Varta, Medalist, A-Mega, Mutlu, Topla, "Act", "Beast".

Comparative tests of various car batteries we spend every year. The most recent results where we compared 10 batteries, you can see those who wish to familiarize themselves with the examinations of past years :,,, etc.

Battery brand, as a rule, determines its price. The approximate cost of European vending accumulators with dimensions 242 × 175 × 190 mm in 2014 was from 3000 to 4800 rubles. For the usual battery, and from 6300 to 7750 rubles. - For AGM. The claimed current and the container will turn out by itself - based on the dimensions.

Important: If you have been installed AGM battery, then it should be changed only on AGM, and not on the "ordinary". The reverse replacement is quite admissible, but it is inexpedient economically.

Now I charge the battery - even just purchased! Our experience shows: in stores under the guise of a new battery, you are happily squeezed "almost new", from which dust wipe out. We charge, connect instead of the old battery, and - the key to the start!

Those who are interested in technical nuances

Is it possible in the cold time before the start of the motor "imitate" the battery with the inclusion of headlights?

Why do you need an eye indicator?

This indicator allows you to roughly estimate the density and level of electrolyte to find out whether the car battery needs in recharging. By and large, this is a toy, because the eye is only in one bank out of six. However, many serious manufacturers at one time were forced to introduce it into the design, since the absence of the eye was perceived by consumers as a flaw.

Is it possible to estimate the state of the car battery voltage on the terminals?

Approximately possible. At room temperature, a fully charged battery, disconnected from loads, should produce at least 12.6-12.7 V.

What is hiding behind the term "calcium battery"?

Nothing special: this is an ordinary advertising move. Yes, the "CA" icons (and then "CA - CA") on car batteries today are still present, but they do not become easier. But calcium - metal is much less severe than lead. The thing is that we are talking about very small (shares or units of percentage) with calcium additives in the alloy from which the batteries are manufactured. If it is added to positive, and in negative electrodes, then the "sa - sa" is obtained. Such car batteries, with other things being equal, it is harder to boil, which is important for maintenance-free batteries. Less in such batteries and self-discharge during storage. Therefore, "ordinary" batteries with the addition of traditional antimony (they usually gives the presence of traffic jams) today on sale almost you will not meet! Note that not everything is so bad in them: for example, they are much better tolerant discharges!

Why do car batteries when checking give the claimed current so long?

Indeed, if the container is 60 A h, then the arithmetic prompts: current in 600 A should be issued about 0.1 hours or 6 minutes! And the real account is just tens of seconds ... The thing is that the battery capacity depends on the current! And with the specified current, the battery capacity is no longer 60 A, but much less: approximately 20-25! The inscription 60 and h speaks only that for 20 hours at a temperature of 25ºС, you can discharge your battery with a current equal to 60/20 \u003d 3A - and nothing more. At the same time, at the end of the discharge, the voltage at the outputs of the battery should not fall below 10.5 V.

Why choose the battery with the claimed current, say, 600 A, if the real need is half less?

The stated current is also an indirect quality indicator of a car battery: the higher it is, the lower its internal resistance! In addition, if you take an extreme case when, God forbid, the oil thickened so much that the starter in generally barely shifts the crankshaft, then the maximum possible current can be needed here.

Is it true that when installing a larger capacity on the car, it will be unsubstituted, and the starter can fail?

No it is not true. What prevents the battery to charge completely? It is appropriate to carry out an analogy: if you cried a glass of water from a bucket or from a huge barrel, then to restore the initial level of fluid, you will need to fasten the same glass from under the tap - both in the bucket and in the barrel. As for the expected starter breakage, its current consumption will not change, even if the battery capacity will grow in a hundred or thousand. Ohm's law from amps-hours does not depend.

Conversations about the upcoming breakdowns are appropriate except for extremals, accustomed to get out of the swamps at the starter. At the same time, the latter, understandable, is very hot, and therefore a small battery, which is discharged largely large, can save it from deadly overheating, dies first ... but this is a hypothetical case.

Immediately note one curious nuance. In Soviet times, on a number of army trucks, it was strictly forbidden to install a larger capacity car battery! But the reason was exactly the fact that when the engine did not want to start, the drivers often circled starters until the battery was discharged completely. At the same time, the starters were severely overheated and often faced. And the higher the battery capacity, the longer it was possible to mock the poor electric motor. It is to protect starters from such mockery that the requirement did not exceed the battery capacity above the "standard" appeared. But now it is irrelevant.

Question per million: What are they measured in amps-hours?

In any case, not the capacity of the batteries! This widespread misconception even in the environment of professionals. Which, however, are lost when they are asked how the product of the current does the container gives? Because the correct answer is this: Ampere-hour - Unit of measurement charge! 1 A h \u003d 3600 CL. And the container is measured in the Farrades: 1F \u003d 1kl / 1 V. Those who do not believe in it can refer to any directories - for example, to Boshevsky.

As for batteries, the confusing terminology is still alive. And what is actually charged is called the tank in the old way. Some textbooks are twisted - they say, "Capacity rate In amps-hours. " Do not measure, but evaluate! Well, that, at least so ...

By the way, in Soviet times, to choose the battery was incomparably easier - only by ampere-hour. Let's say on the "Volga" it was necessary to look for a car battery at 60 a h, on "Zhiguli" -55 a h. Polarity and terminals on domestic cars were the same. Today, it is not necessary to navigate only on the ampere hours, since products of different manufacturers can be quite different at other parameters. Let's say, the batteries of 60 a h can have a 11 percent variation in height, 28 percent according to the claimed current, etc. At the same time, prices also live their lives.

And last. If, instead of "a h", you will see the inscription "A / C" (on the label, in the article, in advertising - it does not matter) - do not associate with this product. It costs uneducated and indifferent people who do not have an elementary presentation of electricity.

What is AGM battery?

The main scope of AGM is cars with "Start Stop" modes. This battery is even indicated: Start Stop!

The main scope of AGM is cars with "Start Stop" modes. This battery is even indicated: Start Stop!

Formally speaking, a car battery AGM is the same lead-acid product to which many generations of motorists are accustomed to, but at the same time it is much more perfect of their ancestors and will completely outset them in the near future.

AGM (Absorbent Glass Mat) is a technology for manufacturing accumulators with absorbed electrolyte, which are impregnated with separator micropores. The free volume of these microporers are used for closed recombination of gases, thereby not allowing water to evaporate. Hydrogen and oxygen, leaving the negative and positive plate, respectively, fall into the associated medium and are again connected, while remaining inside the battery. The internal resistance of such a battery is lower than that of the "liquid" predecessors, since the conductivity of the separator from fiberglass is better compared to traditional "envelopes" from polyethylene. Therefore, it is able to give higher currents. A tightly compressed package of plates interferes with the active mass to crumble, which allows you to withstand deep cyclic discharges. Such a car battery can work up to the legs. And if you split it into it, then even in this case there will be no poisonous puddles: the associated electrolyte must remain in separators.

Today's applications of AGM are cars with the "Start-Stop" mode, machines with increased power consumption (MES, "ambulance"), etc. But tomorrow "Simple" car battery will slowly go to the story ...

Are Agm and Conventional Batteries with each other?

AGM car battery replaces the "normal" 100%. Does such a replacement need if the car is enough good full battery is another question. But the reverse replacement, of course, is defective - it can be applied in practice only in a hopeless situation and as a temporary option.

Is it true that the car battery AGM is 50 a hours can be used instead of the usual 90 a h?

This, sorry, nonsense. How can you almost double to reduce the charge and say that there will be no difference? Lost ampere-clock does not compensate for any technology, even AGM.

Is it true that the high current of the battery AGM can destroy the car starter?

Of course not. The current is determined by the load resistance, and in this case - the starter. And even if the car battery can issue a current at a million amps, the starter will take exactly as much as from the ordinary battery. Violating the law of Ohm is not under power.

Which car is undesirable to apply AGM?

There is no such restriction. Even if we consider ancient machines with an absolutely defective relay-regulator and unstable voltage in the network, then in this case the AGM car battery is lined not before usual, but even later. The limit voltage above which trouble is possible is approximately 14.5 V for conventional batteries and 14.8 V for AGM.

What car battery is stronger afraid of deep discharge - AGM or ordinary?

Normal. After 5-6 deep discharges, they can finally "offended", while for AGM this number is practically unlimited.

Is it possible to count the car battery AGM fully maintenance?

This is a matter of well-established terminology, working more in favor of the PR, rather than science. Strictly speaking, this term is incorrect - both for AGM batteries and for any other car batteries. The fully challenged can be called except that the aa's finger battery, and any lead car battery, generally speaking, is not. Even the leader of the technology is AGM battery - is a hermetic, let's say, by 99%, but not 100%. And still you need to maintain such a battery - check charge, recharge if necessary, etc.

What do gel batteries differ from AGM?

At a minimum, the fact that gel car batteries ... does not exist! The question is generated by the established incorrect terminology: gel batteries are used, for example, in electric loaders or polomotive machines. The electrolyte in them, in contrast to conventional car batteries with liquid acid, is in a thickened state. In rechargeable batteries with AGM technology, electrolyte is connected (saturator) in a special separator from fiberglass.

Note that the most popular Optima battery is also AGM, and not gel at all.

What is the reserve capacity of the battery?

This parameter shows how long the car will last a cold rainy at night, which has a spoiled generator. The expert will say otherwise: for how many minutes the voltage on the terminals of the battery issuing a current of 25 A will decrease to 10.5 V. Measurements are carried out at 25 ° C. The higher the result, the better.

How to choose a battery on a car brand?

Before each motorist, sooner or later the question arises about the selection of a new rechargeable battery. The easiest way to be the drivers that are serviced on the maintenance station certified car manufacturer. Experts will install here exactly the battery that is specified in the instructions. True, the service is very expensive.

If you prefer to buy ankb in auto shops, you need to be guided by the following rule:

• on and with an engine capacity up to 1.6 liters go acr to 45-55 amps / hours;
• universals with a volume of 1.3-1.9 liters - 60 amps / hours;
• and 1.5-2.3 liters - 66 amps / hours;
• trucks weighing up to 3.5 tons and engine capacity of 1.6-3.2 liters - 77 amps / hours;
• cargo cars of the middle class 1.9-4.5 liters - 90 amps / hours;
• saddle tractors - 2 AKB of 200 Ah.

It is clear that in each particular case you need to be guided by the recommendations of the manufacturer. In addition, you can easily find catalogs, including on the Internet, where you will find information on any car model.

Basic battery packs

From how the battery you purchased will be, the operability of the car depends. Nobody wants to try unsuccessfully in the winter in the winter. . If you buy ankb from a proven manufacturer, you do not have to face problems.

Manufacturer

• EXIDE is a global leader in this direction, the products are very expensive, but easily departs 5-7 years, even with a taxi installation;
• Varta, Bosch - German Akb, recommended by German car manufacturers, serve well and for a long time;
• Medalist - Joint trademark of the United States and South Korea, Korean cars are equipped with ankb of precisely this brand;
• Mutlu, Inci Aku - Turkish Batteries of Excellent Quality.

Products and other factories are very appreciated, for example, the Westa Dnepropetrovsk enterprise produces Vortex, Forse. They refer to the average price segment. And for example, batteries from another Ukrainian company - A-mega - are sent straight to Fiat plants.

You can still remember the Akb Topla (Slovenia), American (USA), Japan Star. Batteries in Belarus are produced - "bison". And the Russian "Kursky current source" has long been in demand from domestic motorists, although there are enough problems with him too. There are also Irkutsk Akthekh - Orion, Beast, Solo, Duo Extra.

All Akb is also divided into classes in their value, the premium segment will serve very well and for a long time. Well, inexpensive batteries often do not reach the end of the warranty - 12-18 months.

Technical characteristics of AKB

The main parameters of batteries include:

Rated voltage. To date, all the passenger cars put 12-volt batteries. For trucks, special equipment, buses, army equipment should be bought 24-volt. Although for light trucks can be approached by 12 volts.

Battery capacity. This parameter is measured in amps clocks (ACH). This is a conditional designation, it suggests that, for example, the AKB of 60 ACs is able to provide a load of 1 amp into 1 amp, or 4 amps for 15 hours for 60 hours. That is why the battery is discharged if you forget to turn off the radio or leave the headlights on the night.

Starting current. Starting current is a current that is served at the starter during engine start. This value is measured in amperes. It is necessary to very carefully pick up the battery with the starting current to which the starter is designed, otherwise two options are possible:

• the starting winding will burn - too large starting current;
• the current forces is not enough to scroll through the starter.

The starting current is not a constant value and depends on the air temperature, the area of \u200b\u200bcontact with the terminals (we noticed that over time the terminals are oxidized or departed and the motor cannot be started?), Battery capacity and charging level.

The value of the start current is indicated on the label and corresponds to the strength of the current at 18 degrees above zero. In winter, the starting current force is reduced and the engine is more complicated, so it is allowed for cold regions to buy an AKB with a starting current reserve - a few dozen amps above.

Yandex_partner_id \u003d 136785; yandex_site_bg_color \u003d "ffffff"; yandex_stat_id \u003d 13; yandex_ad_format \u003d "direct"; yandex_font_size \u003d 1; yandex_direct_type \u003d "horizontal"; yandex_direct_limit \u003d 1; yandex_direct_title_font_size \u003d 2; yandex_direct_links_underline \u003d true; yandex_direct_bg_color \u003d "f0f0f0"; yandex_direct_title_color \u003d "0000cc"; yandex_direct_url_color \u003d "006600"; yandex_direct_text_color \u003d "000000"; yandex_direct_hover_color \u003d "ff0000"; yandex_direct_sitelinks_color \u003d "0000cc"; yandex_direct_favicon \u003d true; yandex_no_sitelinks \u003d false; document.write ("");

Also note that the starting current can be measured by the standards differing from each other: EN (European), DIN (Germany) and GOST (Russia) - they are measured equally, SAE (USA). For example, if you buy a "sixtiest" a mega, it will be written on it:

• starting current EN - 600 amp;
• DIN - 365 A;
• SAE - 650 A.

That is, this difference must be taken into account, the sellers of consultants must be tables for different standards.

Polarity is the position of the plus and minus electrodes of the AKB.

She may be:

• direct - positive terminal is located on the left (the battery will turn to you the same side on which the terminals);
• reverse - plus on the right.

Accordingly, you can see the designations of the AKB: 60 (0) Ach - right plus, 60 (1) Ah - left plus.

If you choose the battery not with that polarity, then maybe not enough wires to put it on the terminal. Also look at the terminals, they can be a standard thickness - European, and subtle - usually among Asian batteries.

Well, note that the new battery is suitable in size and by fastening method.

Incorrectly chosen battery

If the battery is incorrect - with a greater or less battery capacity, it will be displayed primarily on the battery itself. If, of course, you did not bought instead of 60-ki 75-ku or "weave" - \u200b\u200bthen you can burn the starter and generally all the wiring.

With too much capacity, the battery will occur the permanent underwear - the generator is unable to develop the required voltage to ensure the charge of the AKB. Over time, you will notice that the electrolyte will become white, and it will be impossible to start the car - the battery will be constantly discharged.

If the battery is selected with less capacity and starting current, then it, on the contrary, will be constantly recharged. Because of this, the process of sanding plates will be much faster, the cans can be closed. An explicit sign of an incorrectly selected battery is a brown electrolyte due to the shied plates.

And in that and in another case, the AKB will not be subject to replacing the complaint.

What else to pay attention to when buying?

The battery is a warranty product, so you have to check it with it:

• measure the density and level of electrolyte;
• measure voltage - 12 volts;
• connect to the load fork and give a load - the battery must hold it (the ammeter arrow holds at 9 a 30 seconds), the electrolyte does not boil and pair does not stand out.

Track out the filling of the warranty coupon, it must be the seal of the company, the signature of the seller, the serial number of the battery, which knocks out on the lid. Warranty card Store at home not to lose it.

A good rechargeable battery serves an average of 5-7 years, depending on the operating conditions.

Also recently there have been many fakes. Do not advise Chinese battery banks, they very quickly fail.

An article on how to choose a battery on a car brand - Important parameters and aspects when buying AKB. At the end of the article - an interesting video about the choice of battery.

The content of the article:

Any motorist may encounter a battery replacement problem, whether he has a new car or a certain mileage already. The rare owner operates the equipment correctly, it will remove from sharp temperature differences and overloads, regularly monitors the battery state. Therefore, not every ACB produces its resource, starting to demonstrate the failures after 3-4 years.

Those owners who serve their transport in a certified car service, are delivered from the need to find the battery on their own. Specialists of the maintenance station will install exactly the ACB, which is recommended in the instructions.

Although this service will cost the driver very expensive, it will be confident in the reliability of the aggregate and the compliance of its technical parameters.

If the owner prefers to choose the battery itself, he should carefully read the recommendations of the manufacturer of his car to subsequently not freeze in the cold in attempts to start the engine.

Key battery packters

Each car brand gives its recommendations for servicing the models produced by them, which can be read in the instruction manual.

The basic principles for selecting the battery, based on the type of body and the volume of the engine, are as follows:

• on machines with a hatchback body and a sedan with a 1.6-liter motor suitable batteries for 45-55 amps / hours;
• for station wagons, having a volume of 1.3 to 1.9 liters, there are batteries by 60 amps / hours;
• for SUVs and crossovers with 1.5-2.3 liters, not less than 66 amps / hours;
• akb from 77 amps / clock and more on cargo vehicles.

The remaining indicators to pay attention to when buying a battery look as follows:

Rated voltage

If cargo transport requires a powerful battery at least 24 volts, then 12-volt batteries are traditionally developed for passenger cars.

Battery capacity

One of the most important parameters when choosing a battery, as it shows that the amount of energy that will be accumulated during charging. Its maximum volume is indicated on the housing in the form of marking type "6st-55", where:

• the first digit indicates the number of batteries in the battery;
• the letters speak of the appointment, in this case - the starting battery;
• the second digit is just the size of the capacity in amps-hours.

It is recommended not to chase over a large volume, but acquire a battery with so much energy that is necessary for the technical parameters. Such a battery does not harm the car, but will not meet the funds nested into it.

Starting current

The current is supplied to the starter when the engine is started, you should choose carefully and carefully. If it exceeds the level to which the starter is designed, it can burn its winding. If the force is insufficient, the starter will not start.

The starting current is not a stable value, as it depends on the set of accompanying indicators: the battery capacity, the level of its charging, the quality of contact with the terminals, even on the air temperature. Starting current size is listed on the battery label and is calculated on the temperature of +18 degrees.

Since the current strength of the current can decrease and slowly start the engine, it is allowed in particularly cold regions to acquire ankb for a couple of dozen amps above the necessary to have a margin of frost.

Some drivers cause doubts for various current measurement standards. The fact is that its value can be indicated in the European equivalent EN, German DIN, American SAE or on Russian GOST. What is not confused, the seller of a specialized store can ask the standards table and select the required parameter.

Polarity

This indicator is important in the fact that when selecting the battery with an incorrect polarity of its wires, it may not be enough to put on the terminals.

Polarity - the position of the minority and positive electrode - it happens different:

• direct when the plus terminal is located on the left;
• reverse when, respectively, on the right.

It looks clear, for example, this way: 60 (1) Ah is the left plus.
Terminals can be varied in thickness, as European has a standard thickness, but Asian will be significantly thinner. For the battery securely attached and approached in size, it is important to take into account similar features of different manufacturers.

Manufacturer

• EXIDE - The company with world name, leader in this industry. The batteries produced by them have a very high cost, but they deserve it. Even under conditions of active operation in any weather, for example, in the taxi service, such ankb will serve at least 5-7 years;
• two German manufacturer - Varta and Bosch. - Ideal for your own car industry, which serves for a long time without complaints;
• Medalist. is a joint venture of the United States and South Korea, whose products are being developed for Korean cars;
• Mutlu and Inciaku. - These are Turkish companies whose quality is located at the highest level and is suitable for different car stamps;
• Westa. - Dnepropetrovsk plant, which produces batteries of the average price segment (Vortex, Forse);
• A-mega. - Ukrainian manufacturer whose products are purchased by Fiat plants.

Companies such as Slovenian Topla, American American, Belarusian "COMBER", the Russian "Kursk Source" should also be mentioned.

For the domestic car industry there will be enough Russian batteries whose work is not much worse than imported analogs, but the cost is much lower.

Although in the context of rechargeable batteries, the price really matters, since cheap batteries very often do not serve not only due time, but do not even reach the end of the warranty. Since the battery is not the equipment on which it should be saved, it is better to give preference to the proven manufacturers.

Year of issue

The manufacturer's date is printed on the battery case or on the label as a simple numerical code or supplemented by lettering and even color values. Each manufacturer marks products in its own way, but it is necessary to pay attention to the first group of numbers. So, in the designation "0317 2 28674" the date - March 2017 will be encrypted.

Excessively large or insufficient battery capacity will somehow affect the operation of the battery itself. As mentioned above, there is a chance to burn wiring and starter when the current is too large.

Overly, the large capacity of the battery will lead to a regular shortage, as the generator cannot produce the voltage required to ensure the charge. Gradually, the electrolyte will acquire a white color, the battery will be discharged, and the engine will start to start worse and worse.

In the inverse situation, when the battery has a smaller capacity, it will be recharged, which will lead to the closure of the batteries and sprinkling the plates. In this case, the symptom of an incorrectly selected battery will be the darkness of the electrolyte to brown.

Since the battery is a warranty product, the seller must maximize it before selling the client. Traditionally, the electrolyte and voltage level is measured, which must be at least 12 volts.

After connecting the battery to the load fork, it must have been kept steady for 30 seconds to keep the load at the mark in 9a, and the electrolyte is not boiled and not evaporate.

The warranty card itself must be maximally full of information about the purchased product: brand, model, battery serial number, warranty period, seller's signature and printing the company.

In addition, the seller can be asked to familiarize the quality certificate, made on the manufacturer's plant.

It is not recommended to purchase Chinese products, since in practice and consumer reviews it fails too quickly. If during the inspection of the battery it seems too easy by weight, the likelihood is great that the manufacturer has established an insufficient number of plates and lead.

Now the car market has too many poor-quality goods and frank fakes, so it is necessary to approach the choice of the battery very carefully.

If you read this instruction, you faced the issue of buying a new battery for your car. How to choose the most suitable device?

A modern range just amazes with its diversity. And it's not just the number of different manufacturers offering our products on the market. Choosing a battery, not enough to be guided by the usual "price-quality".

Be sure to consider several important indicators, non-compliance with which is able to cause damage to the car or significantly reduce its operational period. And the battery corresponding to all necessary characteristics will not only serve you by faith and truth, he will not be able to cause damage or lead to the creation of a dangerous situation.

Causes of the output of the battery

Before you expire to the selection of a new battery, it is necessary to find out and eliminate the reason why old old has ceased to work. On average, the vehicle source is designed for 5-7 years of operation. If its resource has been exhausted faster, malfunctions are possible in the electrical circuit. The main perpetrators are the starter and the generator, the decrease in the functionality of which leads to increased consumption of electricity during the launch. The appearance of the used battery will help a specialist to understand this matter.

Selection of car battery - Criteria

When choosing a battery, you need to consider many technical factors, including voltage, shape and location of the terminals, dimensions, containers, starting current or cold start current. Here are some tips to help simplify the task.

1. Capacity

This is the main indicator. It is governed by a majority of automakers and varies depending on the type of vehicle and is:

• 45-55 a / h - automobiles with an engine up to 1.6 (sedans and hatchbacks);
• ~ 60 a / h - station wagons 1.3-1.9 l;
• ~ 66 A / h - SUVs and crossovers;
• 77-90 A / h - trucks and heavy machinery.

You should buy a battery with the same container as the manufacturer recommends. Permissible exceeding this value is no more than 5%. The battery with an increased capacity will be constantly dissimilar, and this will create an increased load on the generator and reduce its service life. You can not buy a current source and with a capacity, less than that of the previous one. Insufficient energy will often lead to its full discharge.

2. Power current power

This is the output power of the battery in the range of 30 s. The higher the number - the faster the starter rotates the engine at startup. Manufacturers are focused on the temperature regime of their region. We all 100% are suitable for German technical specifications.

When buying Japanese, Korean or Turkish batteries, you will need to take into account the difference in measurements. The starting current indicator is especially important for regions with low winter or extreme high summer temperatures. In such conditions of the standard current entering the starter, there will be little to start the engine.

3. Dimensions

Batteries for different brands have standard dimensions and sizes of terminal connectors. In some cases, differences are quite significant. And most of all, they are found in the products of the Japanese car industry.

Japanese batteries are often already or higher than standard. The inconsistency of the size will make a reliable fixation of the battery impossible and cause damage or short circuit.

4. Location of output terminals

The length of the power wires in cars is minimal, and the elongation of the wiring is fraught with consequences. Directly called the location of the output terminal "+" on the right side.

Reverse polarity will become a source of trouble. If "minus" is not located on the other side, the wires for connecting is simply not enough. And if you connect incorrectly - you have to buy another battery.

5. Manufacturer

Manufacturers can be conditionally divided into three price categories: Economy, Standard and Premium. It all depends on the amount you are ready to part. In practice, it is proved: well and long serves the products of the world leader Bosch and Varta. Korean Medalist, and Turkish Inci Aku or Multi showed well. Not bad batteries are produced absolute, bison, forse, a-mega.

We are in demand and domestic Duo Extra, Beast, Orion and Solo. The expensive devices will serve until the end of the stated period, economy - for 12-18 months will not be long before him. Each class has decent options, there are folk ratings.

But do not forget: there is always a risk to face fake. We advise you to pay attention to small details. Copy manufacturers do not always give value to such trifles as matching the manufacturer's plants, date and time of release. Inspect the terminals carefully, their protective caps, corks and housing for irregularities. Make sure there is a softwareport.

6. Opportunity service

There are served, low-service and maintenance-free models.

1. The first gradually go into the past. The service life is limited to two years, and the owner will have to constantly monitor the level of electrolyte and add distilled water.
2. A low-service batteries manufactured on the basis of lead-antimunct plates can be called them improved option. They serve to three years and require less attention. Access to electrolyte maintenanceable models for motorist is closed. They are durable and self-sufficient.

7. Selection of model range
