Remove the battery correctly! Malfunction of the Mazda CX 5 rechargeable battery.

What should be fuel consumption in a 150-strong two-liter engine that disperses two-ton crossover Mazda CX-5? It would seem - not small. But in fact, thanks to the intellectual SMART system i-Stop., turning off the engine, even with short-term stops, work on idling Coming down to a minimum. The result is the Motor CX-5 consumes about one and a half times less than fuel than its "classmates" ( Nissan X-Trail, Tiguan, Audi Q3, Q5). However, the frequent stops / start-ups of the engine presented special requirements for the power supply of the car.

Effect of I-STOP system on Mazda CX 5

It is known that the maximum current battery gives when the engine is started. Next, its partial discharge is compensated by recharging from the generator. If after the long-lasting trip on the highway follows, then the CX-5 Mazda battery is charged in a common source for most. When driving in the urban cycle, each car stop launches the i-STOP system, and the generator work stops. On the battery for Mazda CX-5 with i-Stop, in addition to the energy source function, the power supply functions of all on-board systems of the vehicle are also superimposed by the power of the engine - audio systems, climate control systems, diagnostic systems, electrical sensors, external lighting and internal illumination, glass heating and mirrors, heated seats, etc.

Effect of the degree of charge of the battery to work the i-STOP system

Not only the i-STOP affects the battery for Mazda CX-5. There is also feedback - the work of the i-STOP depends on the degree of charge. The parameter characterizing the battery charge state is expressed as a percentage and called State of Charge. or simply SOC. For the correct operation of the i-STOP system, the SOC indicator should be above 85%. And at SOC, less than 68.4% I-STOP stops working at all.

Smart Charging Akb CX-5

Fully compensate for the loss of electrical energy when operating the i-STOP system in the urban cycle is impossible, but Mazda engineers worked out that even with frequent shutdown / engine launch battery Mazda CX-5 2.0 standard equipment I received maximum recharging. It was achieved by the introduction of the so-called intellectual System Charging (smart charging).

When slowing the car, caused by a decrease in the supply of fuel to the engine cylinders or braking cars (by braking, either by braking by engine), the current sensor automatically increases the voltage of the generator, thereby allowing additional accumulation electric energy To charge the battery. In addition, smart smart charging allows you to use the kinetic energy of the car, reducing the load on the generator, which also has a positive effect on fuel economy. Of course, the "fast charging" of high currents is not the most the best way Preserving the long-term operation of any power source, but so far nothing better in this area is invented.

IMPORTANT! Use the "Quick Charging" mode when charging using the charger is not allowed. Ignoring this comment can lead to the failure of the I-STOP system.

Charging the battery Mazda CX 5 at home

The degree of discharge intensity depends on many factors. These include: enabling the security alarm, opening / closing the doors / hood, position of the automatic transmission arm (to minimize leaks it is recommended to leave an uncutable car with the automatic transmission lever installed in the "P" position) and even finding a car in the cabin or near it ("Washing Map"). Therefore, the overwhelming majority of the owners of Mazda CX-5 sooner or later will require additional charging of the battery of their cars. Do it at home is quite real with the help of a special charger. MAZDA CX-5 MAZDA CX-5 manual recommends this procedure every 2-3 weeks.

Consider how to charge the battery on the Mazda CX 5.

To begin, it is necessary to establish the fact of the need for charging the battery, i.e. Rate SOC. This is done by measuring the density of the electrolyte using the hydrometer. It should be remembered for the effect on this temperature indicator. ambient. Match the density of the electrolyte at a given air temperature with the SOC indicator on tables that contain special reference books both printed and online.

For example, at ambient temperature, 20 degrees SOC \u003d 100% will correspond to the electrolyte density of 1.280 g / cm cu., SOC \u003d 85% - 1.262 g / cm cu., 65% - 1.234 g / cm cu., Respectively. At a lower ambient temperature, the electrolyte density corresponding to a specific SOC level will be higher at a higher temperature below. To have a complete table of compliance with the electrolyte density, SOC level at different temperatures is optional. It is enough to remember the formula of bringing:

The density of the electrolyte (at T \u003d 20 o C) \u003d the measured value of the density + (the actual temperature of OS - 20) x 0.0007.

Before charging the Mazda Cx 5 battery, mark the most discharged jar. Based on the electrolyte density in it, the battery charge time is selected on the tables. For example, the density of more than 1.24 says that the charge time is 180 minutes, and the density of 1.17 will require for a full charge for 360 minutes. It follows a constant current of 10 amps, checking and adjusting (if necessary) current strength every 60 minutes.

Evaluation of SOC (electrolyte density) is carried out 6-48 hours after charging. If the electrolyte density in one of the cans is less than 1.25, then you should think about buying a new battery.

In the autumn-winter period, the number of electricity consumers is significantly increasing. Additional loads are given by the above-mentioned climate control, heat heating and mirrors, heated seats, as a result of which the discharge occurs much faster than in the summer. At one fine moment, the car may simply get started. Some car enthusiasts in this situation work on the protection - turn off I-STOP. About saving fuel in this situation can be forgotten. Engine Auto and power supply Mazda CX 5 work in the same mode as hundreds of other car models. Option Two - to purchase and always carry with you the external source of electricity - an autonomous commissioning device. This will allow, if necessary, make an emergency launch of a car motor.

The modern autonomous commissioning device (booster) does not take up much space. It can be used if necessary for launch of DVSand to replenish the charge of the standard energy source. After starting the engine, the charge's own booster can be filled immediately by connecting it to the electric network of the car through the cigarette lighter connector.

Replacing the battery Mazda CX-5

Follow the level of charge rechargeable battery very important. When SOC drops below 25% (electrolyte density before charging below 1.17), the battery recovery will be very problematic. In the plates, irreversible changes occur, which will not allow you to recruit and hold the charge for stable work I-STOP systems.

How to change the battery on Mazda CX 5

The procedure for replacing the ACB on the Mazda 5 is very simple. First of all, you should remove the old battery:

1. Disconnect the current sensor from the minus terminal. By this, we de-energize the on-board computer, not allowing the possible passing of an erroneous engine control signal.
2. Remove the minus terminal.
3. Remove the positive terminal.
4. Remove the fixing bar.

Install new battery Mazda CX 5 follows 1 minute after removing the old one. For this small temporary gap from the memory of the PCM block (Powertrain Control Module - it is the "brains") information about the state of the old battery will be deleted. Installing a new battery is made in the sequence, reverse removal.

After installing a new battery, it must be "prescribed" in the system:

1. When the engine is turned off, set the engine start switch to ON.
2. Install the automatic transmission lever to the "Neutral" position.
3. When the brake pedal is pressed:

• press and hold at least 5 seconds gas pedal. Should start flashing the battery charge akb and the main warning signaling device;
• press and let go of the gas pedal. Account signaling device and the main warning signaling device should go out.

If the car Mazda CX-5 is equipped with an LCD display of the device's combination, before installing the engine start switch to ON, you must close all the doors, after installation - wait for the warning message on the display, then remove it with the Info switch located on the steering wheel.

To check how correctly the Mazda CX-5 battery is passed, it is necessary to turn on the ignition, then press and hold 10 seconds the I-STOP switch. A flashing green indicator will mean a successful passage of the initialization procedure of the ACB. A flashing yellow signaling device means an underwear or recharge battery. A constantly burning yellow alarm means that the battery initialization in the system is not fulfilled, it is required to repeat it.

For the correct initialization of the AKB of its SOC must be more than 75%.

What battery can be put on Mazda CX-5

Given the specifics of the I-STOP system, the manufacturer strongly recommends using the original Mazda CX-5 battery, which can be clarified by the Mazda catalogs. In addition, comprehensive information on which battery to put Mazda CX-5 can be obtained from specialists from authorized service centers Mazda. Initially, the conveyor Mazda CX-5 crossover was completed with 65-ampered batteries GS Yuasa. Q-85 . Today the line of permissible batteries expanded significantly. To find out which battery is in Mazda CX 5, you can, having studied the sticker on its case. When choosing a battery, different from the one that the car was completed on the conveyor, take into account not only the capacity and starting current (for models with a two-liter engine - a starting current of 540 a * h, for engine models with a volume of 2.2 liters - 640 a * h), but and type ( AGM / EFB.).

It is very important to pay attention to dimensions. Extremely dense layout open space obliges to withstand them especially carefully. The owners of a two-liter motor must select Akb corresponding to the size of 202 x 230 x 172 mm (height x Length x Width), the model of 2.2 liters will request a longer niche - 202 x 255 x 172 mm - battery marking

Most often, domestic car owners are faced with the impossibility of starting the engine of the machine due to the seal or non-working battery. That is why every car enthusiast should monitor the operation of the battery and to change it in a timely manner. This material will allow you to learn how to choose a Mazda battery 6, and what should be considered when buying.

In which cases it is necessary to change the native battery?

First you need to say that the need to replace this product in the machine occur if the device does not cope with its primary functions. The device is not able to keep charge, and after another charging it is quickly discharged.

Battery malfunctions may indicate such signs:

1. First of all, this is a reduced charge. The diagnosis of this parameter is carried out using the tester.
2. In banks, there is no liquid. Its absence may be due to the presence of cracks on the housing, as well as bumping. Ringing, as a rule, is associated with the destruction of the plates inside the design, such a problem is not "treated."
3. Damage to the battery case. If cracks appeared on the battery case, it can lead to leakage working fluid - electrolyte solution. For insufficient level Water The device will also not be able to perform its functions.
4. Mechanical damage to the terminals. Due to damage to the contacts, the device will not be able to normally feed the electrical equipment of the car (the author of the video is the battery).

How to choose ankb?

Now details on how to choose a product and what to pay attention to when buying.

Selection parameters

1. If you want to purchase the original AKB, then it is better to buy the same model as installed on your car. Of course, if the product has not changed after buying a car from the cabin.
2. pay attention to specifications, in particular, the product capacity, as well as the value of the start current. These parameters are marked in the Device Operating Standard, so carefully examine the manual. If you do not know what characteristics should have the battery specifically for your car model, then carefully examine the housing of the already installed battery. It must contain the values \u200b\u200bof the tank and starting current.
3. Specify the dimensions. Product dimensions may differ depending on the model vehicle, as well as year of release. On Mazda cars, most products are used in size 20.2 * 23 * 17.2 cm and 20.2 * 25.5 * 17.2. Just in case, with the help of roulette, measure the dimensions of the product.
4. You should also familiarize yourself with the technical documentation for the car. It can accurately indicate models of devices that are allowed in a particular machine.

Manufacturers and brands

Limitations in terms of choosing a product according to the manufacturer, in general, no.

In Mazda cars, devices must be applied, which correspond to such characteristics:

• capacity should be from 50 to 65 Ah;
• most importantly - in Mazdah used batteries with reverse polarity.

As for specifically models, their superiority and attention of our compatriots have deserved such products:

1. Varta Bloi D47 speaker. In this case, the tank value is 60 Ah, and the current scroll current is 540 amps.
2. Bosch C5 004 Silver Plus. As you know, the manufacturer of Bosch is engaged in the release not only the battery, but the batteries of this brand usually do not have complaints. In the case of this model, the capacity indicator is 61 Ah, and the value of the current scrolling current is about 600 amps (the author of the video is the MERAK channel).

Instructions for dismantling and installing acb with your own hands

There is also nothing complicated in replacing the device:

1. First you need to turn off the ignition and open the car hood.
2. Next, using a wrench, you must unscrew the terminals from the battery and disconnect them. Evaluate the Terminals themselves - if necessary, they need to be cleaned with the help of sandwich or brushes.
3. The product itself is fixed in landing place With the help of a plank or bracket, depending on the car model. As a rule, it is fastenings on nuts, so using a wrench, they must be unscrewed. Plank or brackets are extracted from the landing place.
4. Next, the device itself is dismantled and changes to the new one. Before installing a new product, clean the place of installation from dust and dirt. Install the new device and connect terminals to it, secure them securely. Check the device performance.

Question price

The cost of goods today can be very different. Cheaper models from unknown manufacturers are located in the area of \u200b\u200b2500 rubles. Middle batteries price category From more well-known manufacturers will cost the buyer about 3-6 thousand rubles. Of course, you can find and expensive options, the cost of which will translate for 7 thousand rubles.

With frequent long-lasting trips by car Mazda CX 5 on the highway, the battery does not require maintenance for several months or years. Trips around the city in Start Stop mode overloads AKB. The I-STOP system developed by Japanese engineers saves fuel at long stops, but it prevents independent recharging from the generator.

Smart charging helps restore density, but it is not enough for a long-term operation of the battery in the city. The instruction manual recommends during the city start-stop downtown, recharge the battery every 2-3 weeks. With a mixed type of city-track, recharging is required as needed. When is it necessary? How to remove, charge, install? When is the replacement, initialization is required? How to execute it?

The battery charge state (SOC - State of Charge) of the Japanese crossover Mazd CX 5 must be maintained at a level not lower than 80%, which corresponds to the density of electrolyte 1.24 kg / l and voltage without load 12.48 V. If the specified values \u200b\u200bare below, immediately required charging.

Replacing the battery is advisable if the discharge occurred to 35%, its voltage dropped to 12.06 V, the electrolyte density reached 1.17 kg / l. With a dedicate discharge, replace the battery will need inevitably.

How to remove and install battery with Mazda CX 5

Removing the Mazda CX 5 battery is performed simply:

• disconnect the current sensor cable from the minus terminal;
• disconnect minus;
• remove plus;
• remove the retainer;
• remove the battery.

Installation is made in order to remove. When manipulating with battery, it is especially important that the sensor cable is first shot first, and put on the latter. So you will avoid errors in the operation of electronics.

Charging

Battery japanese cars Mazda CX 5 is charged with constant current 10a. In order to accelerate the process, some owners increase current strength to 15a, but this adversely affects the battery life. There are known occasions when the CX 5 Mazda battery is used to charge 5a for extending service.

Most comfortable I. simple way Charging is the use of an automated device. CTEK MXS 10 meets all the requirements of the Mazda CX 5. It allows you to charge both indoors and without removing the battery from the car.

Using a charger requiring manual adjustmentYou must first measure the electrolyte density in each bank of the battery. It is usually different, you need to focus on the minimum reading.

The rate of density depends on the ambient temperature. At home it is about 22-23 ° C. At density:

• 1.24 kg / l charge the battery with constant current 10a for 2 hours;
• 1.21 kg / l - 2.5 hours;
• 1,17-1.18 kg / l - 3 hours.

Highly check the current strength, adjust to 10a if necessary.

After charging the battery, it is recommended to leave one day at rest. If there is no such possibility, it is desirable to wait at least 6 hours. After measuring density in banks. At room temperature, it must be 1.25-1.27 kg / l. If the indicator is below, and you are confident in the serviceability of the charger, the battery life from your car has expired, it will have to be replaced.

Stabilization and initialization of AKB

The procedure is also called registration, it is required when replacing the new battery, charging the old to synchronize the battery and the Japanese side computer.

The initialization process of the AKB on Mazda CX 5:

• when the engine is turned off, set the switch to the ON position;
• models with displays display a warning message, disconnect it through the info button;
• install a neutral gear lever;
• hold the brake;
• when the brake is squeezed, press the gas pedal, the indicators on the panel will light up for a few seconds;
• not releasing the brake, press gas three times, release it, the indicators should go out;
• release the brake.

Initialization control is performed by pressing and holding the i-STOP system button. With a correctly prescribed battery, the i-STOP indicator will flash green. When flashing yellow initialization after removal is made with an error, repeat it.

Remember the timely check of the Account charge. This is especially true in frost and with frequent trips in start-stop mode. The freezing temperature of the electrolyte increases inversely proportional to its density. So, at 1.27 kg / l, the electrolyte does not freeze up to -60 ° C, for 1.17 kg / l enough -16 ° C to freeze.

Cars with i-Stop function And with the engine SkyActiv-G-2,0 and SkyActiv-G-2.5, the Q-85 battery is equipped specifically designed for this mode. SkyActiv-D-2,2 engine T-110 battery.

Cars without i-StopFor SkyActiv-G engines, can be equipped with any batteries that are suitable for the manufacturer of the car manufacturer: 12V-55Ah / 20HR or 12B-65Ah / 20HR.

Mazda CX-5. EFB or AGM battery choose?

If the car without the i-Stop function, choose the appropriate parameters, the battery of any company. If the budget is small, inexpensive lead-acid (antimunct) batteries are suitable. If the budget allows, then calcium (CA / CA) batteries made using EFB or AGM (Absorbent Glass Mat) technology.

For vehicles with I-STOP, the manufacturer usually recommends the original battery for Mazda car.
This battery has the designation - for Stop & Start. In addition to the original battery (Article PE1T185209B), now a large selection of third-party batteries. These batteries are manufactured using EFB or AGM technology, for vehicles with start-stop system. The batteries differ in high current when starting, fast charge acceptance, resistance to deep discharge, low evaporation of liquid electrolyte in the EFB battery, there is no liquid electrolyte in AGM. Not afraid of low and high temperatures, from -50 to +60 ° C.
When on car, keep the necessary security measures.

CX 5 is a fairly reliable unit, and will serve for a long time, if you accurately comply with the conditions for its operation. It is not so difficult, however, the battery requires more than, for example, a shock absorber boot.

Mazda CX 5 battery features

The main indicator of the state of the battery (AKB) is the degree of charging. In the official Mazda documentation, this important parameter is indicated as State of Charge (SOC). The normal operating conditions of the battery are the SOC Range of 80-100%. When using a car for long trips without frequent stops, the battery does not require special recharging: the energy used automatically is replenished using the generator.

But the operation of Mazda CX 5 in the conditions of the city leads to the fact that the SOC is constantly decreasing - the battery is the task of maintaining in the working state of the on-board computer and the numerous electrical equipment of the car on time to work with the engine disconnected, and the generator simply does not have time to fill the losses on the launch of the car for relatively short-term Ride periods.

This is especially facilitated by the i-STOP system, automatically stopping the engine at long stops on traffic lights and traffic jams. At all, it was during such stops that the generator could have accumulated energy. Partially this problem is solved by a special smart charging, which is equipped with Mazda CX 5.

Reference! Smart charging is a special system of "help" car battery. Smart charging increases the generator voltage before stopping (tracks the force in brake cylinders and engine speed), uses the kinetic energy of the car for charging, as well as in other ways "facilitates life" by the automotive battery.

However, even this system cannot fully compensate the battery loss when driving on urban conditions using i-STOP. On average, the loss of SOC is about 1.16% per day. It is not difficult to calculate that under such conditions the SOC will decrease to the operational minimum (80%) for 17-18 days. Indeed, Manual recommends charging the battery every 2-3 weeks.

If you are operating a car in a mixed (country-urban) mode, you can charge the battery on the Mazdacx 5 of the need. To independently define the SOC level, the density of the electrolyte should be measured using the hydrometer. Dependence between electrolyte density, Soc and battery voltage, see the table.

If there is a need to charge the battery, it is easy to do at home.

Charging at home

It is necessary to determine the charging time of the battery. To do this, the electrolyte density is again. At a density of 1.24 kg / l, the charging time will be 2 hours, at 1.17 kg / l - 3 hours.

The CX 5 Mazda battery is charged with a constant current of 10 ampel. AV process charging The strength of the current may vary, so it is checked at least once a hour.

After the end of the time stopped for charging, the battery is turned off from the current source and leave for 12-24 hours (if there is no such possibility - at least 6). After that, the density of electrolyte is measured again in all (!) Banks. The value should not differ from the corresponding SOC 100%, more than 0.02 kg / l. For room temperature (22c O), the density in each of the cans of the battery should be at least 1.25 kg / l. Otherwise, it's time to think about replacing the rechargeable battery.

Battery initialization

It makes no sense to describe in detail a fairly simple procedure for removing the old battery and installing a new battery on Mazda CX 5. Separately, it is worth staying on the initialization procedure.

Initialization - a kind of "acquaintance" of the new battery with on-board computer, his "registration" in the system. The procedure is performed like this:

1. The engine is turned off, after which the switch is driven to ON.
2. The lever of the checkpoint or the "automaton" selector is given to N.
3. Press the brake pedal and not let go!
4. Press gas and keep the battery charge indicator and Master Warning to sunbathing.
5. Press and let go of the gas - Akb and MasterWarning should go out three times.
6. You can let go brake.

The battery initialization is completed. You can check the correctness of the initialization by closing the button of the Ai-stop button. The flashing of the green indicator I-STOP will indicate that the new battery is "prescribed" in the system correctly.
