Battery — Maintenance

Battery Location

Battery 1 is installed in a plastic casing in the engine compartment on the left side.

Warning! Handle the battery with care: the electrolyte contains sulfuric acid. If drops of electrolyte get on parts of the car or exposed areas of the body, immediately wash with soap and water, and then rinse with plenty of clean water.

Attention! Do not smoke or use open flames while charging the battery.

Attention! When removing the battery, first disconnect the wire from the terminal «-», and then from the terminal «+». Connect the wires to the battery terminals in reverse order.

Attention! Do not expose the battery to sunlight.

Attention! When preparing for winter operation, fully charge the battery, as a discharged battery can freeze even at a slight negative temperature. Disconnecting and connecting the battery

Attention! It is forbidden to disconnect the wire from the terminal «-» battery while the engine is running or the ignition is on - this may damage the electronic equipment.

1. Press the plastic loops 2 aside and fold the fuse box 1 closed with a lid (3 - storage battery; 4 - terminal «+» battery; 5 - terminal «-» battery; 6 - latch).



2. Loosen the nut 1 fastening the tip 3 of the wire to the terminal «-» battery (2 - bolt).

3. Disconnect the wire end from the terminal «-».

4. Move the tip aside so that it cannot touch the terminal.

5. When connecting the wire, tighten the fastening nut 1 so that the tip 3 cannot be moved from the terminal by hand.

Checking the electrolyte level

Periodically check the electrolyte level in the battery, as during operation it decreases due to the evaporation of water that is part of it. The level must be between the MIN and MAX marks on the battery case. If the electrolyte level drops to the MIN·mark or below, add distilled water to the MAX mark by removing the plugs.

Electrolyte Density Check

The density of the electrolyte can only be measured two hours after adjusting its level: the water must mix with the electrolyte. To check, fully insert the hydrometer into the hole until it stops and select the electrolyte with a pear so that the hydrometer float floats. The division on the float, which is at the level of the electrolyte, shows its density. Since the density depends on the temperature of the electrolyte, it is necessary to correct the measurement result.

Electrolyte temperature,°С	Correction, g/cm3
-40 to -26	-0,04
-25 to -11	-0,03
-10 to +4	-0,02
+5 to +19	-0,01
+20 to +30	0,00
+31 to +45	+0,01

By density, you can judge the degree of battery discharge (see table. Electrolyte density at 25°C, g/cm³). If the density is below normal or differs in banks by more than 0.02 g/cm³, need to recharge the battery. After checking, drain the electrolyte from the hydrometer into a battery can.

Moderate (-15 to -8)	Same	1,28	1,24	1,20
warm humid (from 0 to +4)	Same	1,23	1,19	1,15
hot dry (-15 to +4)	Same	1,23	1,19	1,15

Charging the battery

Attention! If you do not remove the battery from the car when recharging, be sure to disconnect both wires from its terminals.

Attention! Before charging, remove the battery from the vehicle, otherwise «boiled» electrolyte can splash out on the body and parts of the car.

To charge the battery, use the charger or charger in accordance with the instructions that came with it.

1. Wipe off dirt from the battery, especially its top, which may have traces of electrolyte.

2. Remove all plugs of cans and connect the charger wires to the battery terminals, observing the polarity, then turn on the charger.

3. Set the charging current to 0.1 of the battery capacity (for a battery with a capacity of 55 Ah - 5.5 A; with a capacity of 65 Ah - 6.5 A, etc.). During charging, periodically adjust the charging current.

4. During charging, regularly check the temperature and density of the electrolyte. If the electrolyte temperature exceeds 40°C, reduce the charging current by half or interrupt charging and let the electrolyte cool down to 27°C.

5. If within two hours the density does not change and a violent «boiling» electrolyte, the battery is fully charged. First turn off the charger, then disconnect the wires from the battery terminals.

6. Measure the density of the electrolyte in all banks. If it is more than normal, take a part of the electrolyte from the jar with a rubber bulb and add the same volume of distilled water. If the density of the electrolyte is less than normal, take some of the electrolyte and add the same amount of electrolyte with a density of 1.40 g/cm³ (see table. Approximate norms for adjusting the density of the electrolyte). Then reconnect the charger and charge the battery for 30 minutes. Again measure the density of the electrolyte and, if necessary, bring it to the norm, as indicated earlier.
