Rules for performing work on a battery
Attention:
- Sulfuric acid, contained in battery electrolyte, is an extremely aggressive and toxic liquid that causes corrosion of most metals.
- If acid gets on clothing, the affected area must be thoroughly washed with plenty of running water.
- If acid comes into contact with skin or eyes, seek immediate medical attention.
- When handling a battery, it is very important to use the following protective measures:
- protect your eyes with work glasses,
- use work clothes and gloves made of acid-resistant materials.
To avoid damage to the battery or even an explosion, do not place the battery near heat sources or sparking objects. Incorrect tightening of threaded connections can cause overheating of contacts, cause failures in electrical systems or even lead to an explosion of the battery.
When charging a battery, oxygen and hydrogen are produced. The mixture of these gases is explosive.
The slightest spark or heat source can cause an explosion that can not only destroy the battery case but also release sulfuric acid into the environment, putting people nearby at risk (damage from battery fragments, acid splashes). Acid splashes are dangerous because, in addition to causing direct harm to health, they can also cause damage to clothing and surrounding objects.
Precautions must be taken to prevent explosion due to careless handling of the battery.
Attention:
- To avoid accidental sparking, make sure that all electrical consumers are switched off.
- If the battery is charged inside a building, the charger must be turned off before connecting or disconnecting the battery.
- Do not place metal objects on the battery as they may cause a short circuit between the terminals.
- Do not use open flame, welding torch, blowtorch, cigarettes or matches near the battery.
Attention:
- The vehicle uses a low water content battery, so there is no need to top up the battery with electrolyte.
- Before disconnecting the battery, wait until the radiator fan of the cooling system stops and wait at least one minute for all vehicle control units to complete the data saving process.
- Some vehicles are equipped with only "TV" type batteries (low mass). To avoid damage to the hood, only use batteries identical to those originally installed.
Removal and installation the battery
Removal the battery
1. Turn off the ignition.
Caution: Before disconnecting the battery, wait until the radiator fan of the cooling system stops and wait at least one minute for all vehicle control units to complete the data saving process.

Note: It is recommended to mark the installation position of the negative battery cable for proper connection during installation.
2. Unscrew the nut (1) of the battery cable.
3. Disconnect the negative battery terminal and move the cable aside.
4. Remove the cover (2) from the positive terminal of the battery.
Note: It is recommended to mark the position of the positive battery cable.
5. Unscrew the nut (3) of the positive terminal of the battery.
6. Move the positive battery cable to the side.
7. Loosen the bolt (4) of the battery bracket.
8. Remove the mounting clamp (5).
9. Remove the battery from the vehicle.
10.If necessary (in case of replacement), loosen the nuts and remove the connecting plates from the battery terminals.
Note: It is recommended to mark the installation position of the battery terminals.
Installing the battery
1. Check the technical condition of the battery.
2. If using a new battery, press the connector plates onto the battery terminals.
Caution: Poor contact may cause electrical system failures.
3. Tighten the nuts of the connecting plates on the battery terminals to a torque of 6 N·m.
4. Installation is carried out in the reverse order of removal.
5. Tighten the threaded connections to the specified tightening torques:
- battery bracket bolt: 12 Nm;
- positive battery terminal nut: 8 N·m;
- negative battery terminal nut: 8 Nm.
