We remove the battery correctly! Mazda cx 5 battery malfunction.

What should be the fuel consumption of a 150-horsepower two-liter engine that accelerates a two-ton crossover Mazda CX-5? It would seem - not small. But in fact, thanks to an intelligent smart system i-stop, which turns off the car engine even with short stops, work on Idling is reduced to a minimum. The result - the CX-5 engine consumes about one and a half times less fuel than its "classmates" ( Nissan x-trail, Tiguan, Audi Q3, Q5). However, frequent stops / starts of the engine place special demands on the power supply of the car.

Influence of the i-stop system on Mazda CX 5 battery

It is known that the battery gives the maximum current when the engine is started. Further, its partial discharge is compensated by recharging from the generator. If this is followed by a long trip on the highway, then the Mazda CX-5 battery is charged in the usual auto mode for most. When driving in an urban cycle, each stop of the car starts the i-stop system, and the generator stops working. The battery for Mazda CX-5 with i-stop, in addition to the function of an energy source for the subsequent start of the engine, is also superimposed on the power supply functions for all on-board systems of the car - audio system, climate control system, diagnostic systems, electrical sensors, external lighting devices and interior lighting, glass heating and mirrors, heated seats, etc.

Influence of the state of charge of the battery on the operation of the i-stop system

Not only i-stop affects the battery for Mazda CX-5. There is also Feedback- i-stop operation depends on the battery charge level. The parameter characterizing the state of charge of the battery is expressed as a percentage and is called State of charge or simply SOC. For the i-stop system to work correctly, the SOC must be above 85%. And if the SOC is less than 68.4%, the i-stop stops working altogether.

Smart charging of the CX-5 battery

It is impossible to fully compensate for the loss of electrical energy during the operation of the i-stop system in the urban cycle, but Mazda engineers took care that, even with frequent shutdowns / starts of the engine, the battery Mazda CX-5 2.0 standard configuration received maximum recharge. This was achieved through the introduction of the so-called intelligent system charging (smart charging).

When the car decelerates, caused by a decrease in the supply of fuel to the engine cylinders or by braking the car (by braking or by braking the engine), the current sensor automatically increases the voltage of the generator, thereby allowing the accumulation of additional electrical energy to charge the battery. In addition, Smart Smart Charging allows the vehicle's kinetic energy to be harnessed, reducing the load on the alternator, which also has a positive effect on fuel economy. Of course, "fast charging" with high currents is not the best The best way preserving the long-term operation of any power source, but so far nothing better has been invented in this area.

IMPORTANT! USING THE “QUICK CHARGE” MODE WHEN CHARGING WITH THE CHARGER IS NOT ALLOWED. IGNORING THIS NOTICE COULD LEAVE THE I-STOP SYSTEM.

Charging the Mazda CX 5 Battery at Home

The intensity of the discharge depends on many factors. These include: turning on the burglar alarm, opening / closing doors / hood, the position of the automatic transmission lever (to minimize leaks, it is recommended to leave an unexploited car with the automatic transmission lever set in the "P" position) and even the presence of the vehicle access key in or near the interior of the car ("Wearable card"). Therefore, the vast majority of Mazda CX-5 owners will sooner or later need additional charging of their car's battery. It is quite possible to do this at home with the help of a special charger... Operation manual (manual) Mazda CX-5 recommends performing this procedure every 2-3 weeks.

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

First, you need to establish the very fact of the need to charge the battery, i.e. evaluate SOC. This is done by measuring the density of the electrolyte with a hydrometer. In this case, one should remember about the effect of temperature on this indicator. environment... You can compare the density of the electrolyte at a given air temperature with the SOC indicator using tables that contain special reference books, both printed and online.

For example, at an ambient temperature of 20 degrees, SOC = 100% will correspond to an electrolyte density of 1.280 g / cc, SOC = 85% - 1.262 g / cc, 65% - 1.234 g / cc, respectively. At a lower ambient temperature, the density of the electrolyte corresponding to a certain SOC level will be higher, at a higher temperature, it will be lower. It is not necessary to have a complete table of correspondences of electrolyte density to SOC levels at different temperatures on hand. It is enough to remember the reduction formula:

Electrolyte density (at t = 20 o C) = measured density value + (actual OS temperature - 20) x 0.0007.

Before charging the Mazda CX 5 battery, mark the battery that has been most drained. Based on the density of the electrolyte in it, the battery charging time is selected from the tables. For example, a density greater than 1.24 means that the charge time will be 180 minutes, while a density of 1.17 will take 360 ​​minutes to fully charge. Charge should direct current 10 amps, checking and adjusting (if necessary) amperage every 60 minutes.

Evaluation of SOC (by density of electrolyte) is carried out 6-48 hours after the end of charging. If the density of the electrolyte 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 increases significantly. An additional load is provided by the above-mentioned climate control, heated glass and mirrors, heated seats, as a result of which the discharge occurs much faster in winter than in summer. At one point, the car may simply not start. Some motorists in this situation work proactively - they turn off the i-stop. You can completely forget about fuel economy in this situation. The car engine and power supply of the Mazda CX 5 operate in the same mode as in hundreds of other car models. Option two - to purchase and always carry with you an external source of electricity - an autonomous starting and charging device. This will allow, if necessary, to carry out an emergency start of the car engine.

A modern autonomous starting-charger (booster) does not take up much space. It can be used, if necessary, as for starting the internal combustion engine, and to replenish the charge of a standard energy source. After starting the engine, the charge of its own booster can be replenished immediately by connecting it to the car's electrical network through the cigarette lighter socket.

Replacing the Mazda CX-5 battery

Monitor the charge level battery very important. If the SOC falls below 25% (the density of the electrolyte before charging is below 1.17), battery recovery will already be very problematic. Irreversible changes take place in the plates, which will not allow to gain and hold for a long time the charge necessary for stable work i-stop systems.

How to change the battery for a Mazda CX 5

The procedure for replacing the battery on the Mazda CX 5 is very simple. The first step is to remove the old battery:

1. Disconnect the current sensor from the negative terminal. This will de-energize the on-board computer, preventing the possible passage of an erroneous engine control signal.
2. Remove the negative terminal.
3. Remove the positive terminal.
4. Remove the retaining bar.

Set new battery Mazda CX 5 follows 1 minute after removing the old one. During this small time gap, information about the state of the old battery will be deleted from the memory of the PCM (Powertrain control module - aka "brains"). The installation of a new battery is carried out in the reverse order of removal.

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

1. With the engine off, set the engine start switch to the ON position.
2. Set the automatic transmission lever to the "neutral" position.
3. With the brake pedal depressed:

• press and hold the gas pedal for at least 5 seconds. The battery charge indicator and the main warning indicator should start flashing;
• press and release the gas pedal three times. The battery charge indicator and main warning indicator should go out.

If the Mazda CX-5 is equipped with an LCD display in the instrument cluster, all doors must be closed before setting the engine start switch to ON, after installation, wait for the warning message to appear on the display, and then delete it with the INFO switch located on the steering wheel.

To check how correct the initialization of the Mazda CX-5 battery was, you must turn on the ignition, then press and hold the i-stop switch for 10 seconds. A flashing green indicator will mean that the battery initialization procedure has been successfully completed. A flashing yellow indicator means undercharge or overcharge of the battery. A permanently lit yellow indicator means that the initialization of the battery in the system has not been completed, it must be repeated.

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

What kind of battery can be put on the Mazda CX-5

Taking into account the specifics of the i-stop system, the manufacturer strongly recommends using the original Mazda CX-5 battery, the article of which can be specified in the Mazda catalogs. In addition, comprehensive information on which battery to supply Mazda CX-5 can be obtained from authorized specialists. service centers Mazda. Initially, Mazda CX-5 crossovers were equipped with 65-ampere batteries from the assembly line. GS Yuasa Q-85... Today, the range of batteries allowed for installation has expanded significantly. You can find out which battery is in the Mazda CX 5 by examining the sticker on its case. When choosing a battery that is different from the one that the car was equipped with on the conveyor, take into account not only the capacity and starting current (for models with a two-liter engine - starting current 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 engine compartment obliges to withstand them especially carefully. Owners of a two-liter engine should choose a battery corresponding to the dimensions of 202 x 230 x 172 mm (height x length x width), a model with a volume 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 inability to start a car engine due to a dead or inoperative battery. That is why every car enthusiast must monitor the performance of the battery and change it in a timely manner. This material will allow you to learn how to choose a Mazda 6 battery and what to consider when buying.

When is it necessary to change the native battery?

To begin with, it must be said that the need to replace this product in the car arises if the device does not cope with its primary functions. The device is not able to hold a charge, and after the next charge it discharges rather quickly.

A battery malfunction may be indicated by the following symptoms:

1. First of all, it is a reduced charge. Diagnostics of this parameter is carried out using a tester.
2. There is no liquid in the battery banks. Its absence may be due to the presence of cracks on the body, as well as boiling away. Boil-off, as a rule, is associated with the destruction of the plates inside the structure, this problem is not "cured".
3. Damage to the battery case. If cracks appear on the battery case, it can lead to leakage. working fluid- electrolyte solution. At insufficient level water appliance 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 power the electrical equipment of the car (the author of the video is Battery).

How to choose a battery?

Now more about how to choose a product and what you should pay attention to when buying.

Selection options

1. If you want to buy an original battery, it is better to buy the same model as installed on your car. Of course, if the product has not been changed after buying a car from the salon.
2. pay attention to specifications, in particular, the capacity of the product, as well as the value of the starting current. These parameters are marked in service book manual, so read the manual carefully. If you do not know what characteristics the battery should have specifically for your car model, then carefully study the case of the already installed battery. It should indicate the values ​​\ u200b \ u200bof capacity and starting current.
3. Check the dimensions. Product dimensions may vary depending on model vehicle, as well as the year of manufacture. Most Mazda cars use products with dimensions of 20.2 * 23 * 17.2 cm and 20.2 * 25.5 * 17.2. Just in case, use a tape measure to measure the dimensions of the product.
4. You should also familiarize yourself with the technical documentation for the car. It can accurately indicate the models of devices that are allowed to be used in a particular machine.

Manufacturers and brands

In general, there are no limitations in terms of choosing a product by manufacturer.

In Mazda cars, devices must be used that meet the following characteristics:

• the capacity should be from 50 to 65 Ah;
• Most importantly, Mazda uses batteries with reverse polarity.

As for the models specifically, the following products deserve their superiority and attention of our compatriots:

1. Warta Blue Speaker D47. In this case, the capacitance value is 60 Ah, and the cold cranking current is 540 amperes.
2. Bosch C5 004 Silver Plus. As you know, the manufacturer Bosch is engaged in the production of not only batteries, but batteries of this brand usually have no complaints. In the case of this model, the capacity indicator is 61 Ah, and the value of the cold cranking current is about 600 amperes (the author of the video is the Merak channel).

Instructions for dismantling and installing the battery with your own hands

Replacing the device is also no big deal:

1. First you need to turn off the ignition and open the hood of the car.
2. Next, using a wrench, you need to unscrew the terminals from the battery and disconnect them. Evaluate the terminals themselves - if necessary, they need to be cleaned with sandpaper or a brush.
3. The product itself is fixed in seat using a bar or bracket, depending on the car model. As a rule, these are fastenings on nuts, therefore, using a wrench, they must be unscrewed. The bar or bracket is removed from the seat.
4. Further, the device itself is dismantled and changed to a new one. Before installing a new product, clean the installation site from dust and dirt. Install a new device and connect the terminals to it, fix them securely. Check the functionality of the device.

Issue price

The cost of goods today can vary greatly. Cheaper models from unknown manufacturers cost around 2,500 rubles. Medium batteries price category from more well-known manufacturers will cost the buyer about 3-6 thousand rubles. Of course, you can find expensive options, the cost of which exceeds 7 thousand rubles.

If you drive your Mazda CX 5 frequently on the highway, the battery does not require maintenance for several months or years. City driving in start-stop mode overloads the battery. The I-stop system, developed by Japanese engineers, significantly saves fuel during long stops, but it prevents self-recharging from the generator.

Smart charging helps to restore density, but it is not enough for long-term correct operation of the battery in the city. The instruction manual recommends recharging the battery every 2-3 weeks during the city start-stop cycle. With a mixed city-highway type, recharging is required as needed. When does the need arise? How to remove, charge, install correctly? When is replacement, initialization required? How do you do it?

State of charge (SOC) Japanese crossover The Mazda CX 5 must be maintained at a level of at least 80%, which corresponds to an electrolyte density of 1.24 kg / l and an no-load voltage of 12.48 V. If the values ​​are below, immediate charging is required.

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

How to remove and install the battery from the Mazda CX 5

Removing the Mazda CX 5 battery is simple:

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

Installation is carried out in the reverse order of removal. When handling the battery, it is especially important that the sensor cable is removed first and put on last. In this way, you will avoid errors in the operation of the electronics.

Charger

Battery japanese cars The Mazda CX 5 is charged with a constant current of 10A. In order to speed up the process, some owners increase the amperage to 15A, but this negatively affects the battery life. The opposite cases are known when a current of 5A is used to charge the Mazda CX 5 battery in order to extend its service life.

Most comfortable and in a simple way charging is the use of an automated device. CTEK MXS 10 meets all the requirements of the Mazda CX 5. Allows charging both indoors and without removing the battery from the car.

Using a charger that requires manual adjustment, you must first measure the density of the electrolyte in each battery bank with a hydrometer. Usually it is different, you need to focus on the minimum reading.

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

• 1.24 kg / l charge the battery with a constant current of 10A for 2 hours;
• 1.21 kg / l - 2.5 hours;
• 1.17-1.18 kg / l - 3 hours.

Check the amperage hourly, adjust to 10A if necessary.

After the end of charging, it is recommended to leave the battery alone for a day. If this is not possible, it is advisable to wait at least 6 hours. Then measure the density in the jars. At room temperature, it should be 1.25-1.27 kg / l. If the indicator is lower, and you are sure that the charger is working properly, the battery life from your car has expired, it will have to be replaced.

Stabilization and initialization of the battery

The procedure is also called registration, it is required when replacing with a new battery, charging the old one to synchronize the battery and the Japanese on-board computer.

The process of initializing the battery on the Mazda CX 5:

• with the engine off, set the switch to the On position;
• models with displays display a warning message, disable it via the Info button;
• set the gearbox lever to neutral;
• release the brake;
• with the brake depressed, press the gas pedal, the indicators on the panel will light up for a few seconds;
• without releasing the brake, press the gas three times, release it, the indicators should go out;
• release the brake.

Initialization control is performed by pressing and holding the i-stop button. If the battery is properly charged, the i-stop indicator will flash green. With flashing amber, initialization after removal failed, please try again.

Remember to check the battery charge in a timely manner. This is especially true in frosty weather and with frequent travel in start-stop mode. The freezing point of an electrolyte rises in inverse proportion to its density. So, at 1.27 kg / l, the electrolyte does not freeze down to -60 ° C, for 1.17 kg / l, -16 ° C is enough to freeze.

Cars with i-stop function and with the engine Skyactiv-G-2.0 and Skyactiv-G-2.5 are equipped with a Q-85 rechargeable battery specially designed for this mode. Skyactiv-D-2,2 engine with T-110 rechargeable battery.

Cars without i-stop, for Skyactiv-G engines, can be equipped with any rechargeable batteries that match the characteristics of the car manufacturer: 12V-55Ah / 20HR or 12V-65Ah / 20HR.

Mazda CX-5. EFB or AGM battery to choose?

If the car does not have the i-stop function, choose a battery of any company suitable for the parameters. If your budget is small, inexpensive lead-acid (antimony) batteries will work. If the budget allows, then calcium (Ca / Ca) batteries made using EFB (Enhanced Flooded Battery) or AGM (Absorbent Glass Mat) technology.

For cars with i-stop system, the manufacturer usually recommends the original Mazda car battery.
Such a battery is designated For Stop & Start. In addition to the original battery (part number PE1T185209B), now big choice third party batteries. These batteries are produced using EFB or AGM technology, for cars with start-stop system. The batteries are characterized by high starting current, fast charge acceptance, deep discharge resistance, low volatility of the liquid electrolyte in the EFB battery, there is no liquid electrolyte in the AGM. Are not afraid of low and high temperature, from -50 to +60 ° C.
When driving, take the necessary safety precautions.

Popular brands of batteries for Mazda CX: VARTA, BOSCH, GS-YUASA, EXIDE, HANKOOK, etc.

When servicing or charging the battery of a Mazda CX car, made using EFB and AGM technologies, follow the recommendations of the battery manufacturer.

CX 5 is a fairly reliable unit, and will last a long time, if the conditions of its operation are strictly observed. It's not that difficult, but the battery requires more attention than, for example, a shock absorber boot.

Features of Mazda CX 5 battery

The main indicator of the condition of the storage battery (accumulator) is the state of charge. In the official Mazda documentation, this important parameter is designated as State Of Charge (SOC). Normal operating conditions for a battery are considered to be in the 80-100% SOC range. When using the car for long trips without frequent stops, the battery does not require special recharging: the energy used is automatically replenished using the generator.

But the operation of the Mazda CX 5 in urban conditions leads to the fact that the SOC is constantly decreasing - the task of maintaining the on-board computer and numerous electrical equipment of the car in working order during operation with the engine off, and the generator simply does not have time to compensate for the losses on starting the car in relatively short-term driving periods.

This is especially facilitated by the i-stop system, which automatically stops the engine during long stops at traffic lights and in traffic jams. After all, it is during such stops that the generator could accumulate energy. Part of this problem is solved by a special smart charger, which is equipped with the Mazda CX 5.

Reference! Smart charging is a special system of "help" to the car battery. Smart charging increases the voltage of the generator before stopping (monitors the force in the brake cylinders and engine speed), uses the kinetic energy of the car to charge, and in other ways "makes life easier" for the car battery.

However, even this system cannot fully compensate for battery losses when driving in urban conditions using i-stop. On average, SOC loss is about 1.16% per day. It is easy to calculate that under such conditions the SOC value will decrease to the operating minimum (80%) in 17-18 days. Indeed, the manual recommends charging the battery every 2-3 weeks.

If you are driving your vehicle in mixed (suburban / urban) mode, you can charge the battery on your Mazdacx 5 as needed. For self-determination of the SOC level, measure the density of the electrolyte using a hydrometer. See the table for the relationship between electrolyte density, SOC and battery voltage.

If it becomes necessary to charge the battery, it is easy to do it at home.

Charging at home

It is necessary to determine the battery charging time. For this, the density of the electrolyte is again required. With a density of 1.24 kg / l, the charging time will be 2 hours, with 1.17 kg / l - 3 hours.

The battery for the Mazda CX 5 is charged with a constant current of 10 amperes. During the charging process, the current strength can change, so it is checked at least once an hour.

After the end of the time allotted for charging, the battery is disconnected from the current source and left for 12-24 hours (if this is not possible, at least 6). Then again measure the density of the electrolyte in all (!) Banks. The value should not differ from the corresponding SOC 100% by more than 0.02 kg / l. For room temperature (22C o), the density in each of the battery cans must be at least 1.25 kg / l. Otherwise, it's time to think about replacing the battery.

Battery initialization

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

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

1. The engine is turned off and the switch is brought to the ON position.
2. The gearshift lever or the automatic machine selector is brought to position N.
3. Press the brake pedal and do not let go!
4. Press the gas and hold it until the battery charge indicator and Master Warning light up.
5. Press and release the gas three times - the battery and MasterWarning should go out.
6. You can release the brake.

Battery initialization completed. You can check the correctness of initialization by holding down the i-stop power button. Blinking of the green i-stop indicator will indicate that the new battery is “registered” in the system correctly.
