Instructions for replacing and initializing the original battery in a Mazda CX-5

Mazda CX-5 belongs to the compact crossover category. At the same time, the model has a good level of spaciousness and is equipped with efficient and economical power units.

The CX-5 was the first to try out the Japanese auto company's new corporate design. The machine is based on the KODO philosophy. The car will be dynamic, fast, stylish and modern.

The new product first appeared on the market back in 2011. It was then that production of the first generation Mazda CX-5 started. Then there was a planned restyling a few years later, and already in 2022 the world saw the second incarnation of the popular Japanese crossover.

Despite the use of a number of modern technologies, car owners can solve some problems related to maintenance and repair on their own. This applies to the purchase and installation of a battery.

To select a battery and replace it correctly, you need to know the characteristic features of the factory battery, as well as take into account the location and requirements for batteries from the Japanese automaker.

What kind of battery is in Mazda CX5

The original Mazda CX-5 battery is installed during assembly. This storage element is necessary for the operation of the vehicle electronics. If the battery is damaged, it is impossible to start the car engine.

The storage element works by converting chemical energy into electrical current. This ensures that the components are supplied with DC current. Due to stabilized power, normal engine starting and operability of all electronic components are ensured. Structurally, it consists of two poles, the contacts of which are connected to the vehicle probes.

In a car, the following components are powered by the battery:

• Motor.
• Sound system.
• Optics, screens and other parts.
• Interior cooling and heating system.
• Wipers.

For installation on a Japanese crossover, it is recommended to install an original galvanic element. This feature arises due to the built-in i-stop technology, which controls most of the drive's operation. It is advisable to undergo diagnostics at service centers before purchasing. Early versions of the car were produced with a Panasonic Q-85 battery. However, with the expansion of the model range, the number of possible galvanic cells has also increased.

To select the right battery, you will need to study the markings of the manufacturing plant, which are usually attached to the battery case. The most important parameters when choosing are the dimensions of the case, the maximum capacitance and the voltage for starting. The batteries of the Japanese crossover have the following characteristics:

• Maximum capacity from 40 to 70 Ampere hours.
• Output power – 12 Volts.
• Electric current for starting 300-700A.

When choosing, you should pay attention to the polarity of the unit and the matching of the connected contacts. The dimensions of the battery are determined by the engine size. Since the Japanese crossover is available with an engine capacity of 2 and 2.2 liters, the dimensions will vary:

• For a two-liter engine, you will need to choose a battery with dimensions of 202x230x172 millimeters.
• The 2.2 engine starts from a battery with dimensions of 202x255x172 millimeters.

The cost of batteries with similar characteristics starts from 7,000 rubles.

Battery markings, reviews

In order not to get confused by the abundance of assortment and to purchase the right part, it is important to be able to read the markings. The manufacturer applies a code to the product, deciphering which you can find out the main technical characteristics of the product.

What is indicated on the battery labeling of the Japanese brand (JIS standardization):

• Mazda CX-5 battery capacity;
• battery width, mm;
• battery length, cm;
• terminal location, polarity (L or R).

Based on reviews from car owners, we found out that the most popular brands in Russia are Varta and Bosch. These brands offer quality products at competitive prices. Good demand is noted for the Bosch S4 02 model (it has a starting current of 540 A and a capacity of 640 Ah). You need to understand that a car with a lot of electronics requires the installation of a high-capacity battery.

In this store you can choose a battery for the Mazda CX-5 depending on the generation and engine.

Battery replacement

The need to replace an outdated battery on a Mazda CX-5 occurs when the maximum power level drops below 25%. You can install the container using a loading fork or another method. A battery that has lost more than three quarters of its charge cannot be restored. The design of the car is simplified, so installation can be carried out even without experience.

The battery replacement procedure includes:

1. You first need to disconnect the electric current sensor from the negative terminal of the old battery to turn off the power to the on-board computer.
2. Disconnect all terminals.
3. Then you need to remove the bar to fix it.

Then, you need to wait about 5-10 minutes until the PCM memory is cleared. Then install the new battery in the reverse order of removing the old one.

Possible problems

Like any part, the battery sooner or later becomes unusable. If the car does not start (especially in frosty weather), it is worth checking the performance of the battery. Possible problems:

1. Battery swelling. If the housing is swollen, the device must be urgently replaced. The cause of deformation may be increased operating temperature.
2. Unpleasant smell of sulfur. This is a battery leak. Failure is also accompanied by the appearance of rust on the terminals.
3. Low fluid level. If the amount of fluid has dropped below the lead plates, top up or replace the battery.

In order for the battery, and with it all electronics, to function properly, it is necessary to carry out diagnostics. A breakdown can be caused by: violation of temperature conditions during operation, insufficient charging, poor-quality electrolyte and much more.

Battery initialization

The action is carried out after connecting the battery and registration. The i-stop system requires a new battery to be initialized in order to operate. Removing the battery resets the settings, so some action is required. Initialization instructions:

1. Start the engine and let it gain speed.
2. Then, press and hold the i-stop button in this position for 10 seconds.
3. On a vehicle with the hood closed, you will need to turn the steering wheel fully.
4. Then stop the engine.

After which, it is possible to check the success of the process by pressing the key that corresponds to the control of the i-stop system in the computer. When the green indicator appears, the battery is working normally.

How to register

For proper operation of the replaced battery, it must be registered in the system. Depending on the presence or absence of a screen, the action will differ. For owners of a vehicle without an LCD panel, the following is required:

1. Turn off the engine.
2. Switch to neutral gear.
3. Press and do not release the brake pedal while performing the following steps;
4. Then you will need to hold down the gas pedal until the indicator activates.
5. Then press the accelerator three times until the indicator light goes off.
6. Remove your foot from the brake pedal.

If you have a screen you will need:

5. Next, press the brake pedal and hold it until the procedure is completed.
6. Apply the accelerator for 5 seconds until the indicator lights up.
7. Then press the gas pedal three times. The indicator light will go out.

After which you will need to carry out the initialization procedure.

Accumulator charging

Basic recommendations from the manufacturer for charging:

1. Always use a 10A constant current charger.
2. In the absence of such a charger, you will have to regulate the supply of electricity.
3. When connecting, pay attention to the polarity.
4. The charging duration is affected by the density of the substance that transmits current inside the battery.
5. After fully charging, you need to leave the vehicle for several hours.

Charging optimization

To increase the charging time and reduce the rate of self-discharge, you will need to follow some recommendations:

• Turn off side lights, radio and other devices that waste energy.
• Do not allow the battery to be completely discharged frequently.
• Do not leave the vehicle in the cold.
• Do not allow the car to remain idle for long periods of time with the key in the lock.
• Always lock your vehicle.

Charging system malfunctions
