Rules for performing work on the battery
Attention:
- Sulfuric acid, found in battery electrolyte, is an extremely corrosive and toxic liquid that is corrosive to most metals.
- If acid gets on clothing, thoroughly rinse the affected area with plenty of running water.
- If acid comes into contact with the skin or eyes, seek immediate medical attention.
- It is very important to use the following protective measures when handling the battery:
- protect eyes with goggles
- use work clothes and gloves made of acid-resistant materials.
To avoid damaging the battery or even causing an explosion, do not place the battery near heat sources or sparking objects. Improper tightening of threaded connections can cause overheating of the contacts, cause malfunctions in electrical systems, or even cause the battery to explode.
During battery charging, 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. Thus people nearby are at risk (battery shrapnel, acid splashes). Acid splashes are dangerous because, in addition to direct harm to health, they can also cause damage to clothing and surrounding objects.
Measures must be taken to prevent an explosion due to careless handling of the battery.
Attention:
- To avoid accidental sparking, make sure that all electrical consumers are turned off.
- If the battery is being charged inside a building, the charger must be switched 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 an open flame, welding torch, blowtorch, cigarettes or matches near the battery.
Attention:
- The vehicle uses a battery with a low water content, so it is not necessary to top up the battery with electrolyte.
- Before disconnecting the battery, you must wait until the radiator fan stops and wait at least one minute for all control units in the vehicle to complete the data saving process.
- Some vehicles are fitted with batteries only "TV" (low mass). To avoid damage to the hood, use only batteries that are identical to those originally installed.
Removing and installing the battery
Removing the battery
1. Turn off the ignition.
Attention: Before disconnecting the battery, you must wait until the radiator fan of the cooling system stops, and also 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. Loosen the nut (1) battery wires.
3. Disconnect the negative battery terminal and put the wire aside.
4. Remove cover (2) from the positive battery terminal.
Note: It is recommended to mark the position of the positive battery cable.
5. Loosen the nut (3) positive battery terminal.
6. Move the positive battery cable to the side.
7. Loosen the bolt (4) battery bracket.
8. Remove mounting clip (5).
9. Remove the battery from the vehicle.
10.If needed (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 a new battery is used, press the connection plates onto the battery terminals.
Attention: Poor contact can cause malfunctions in electrical systems.
3. Tighten the nuts of the connecting plates on the battery terminals to a torque of 6 Nm.
4. Installation is made in an order, the return to removal.
5. Tighten screw connections to the specified tightening torques:
- battery bracket bolt: 12 Nm;
- battery positive terminal nut: 8 Nm;
- battery negative terminal nut: 8 Nm.
