Warnings:
- Do not smoke or use open flames while charging the battery.
- Before charging, remove the battery from the vehicle, otherwise «boiled» electrolyte can splash out on the body and parts of the car.
Recommendations:
- Wipe off dirt from the battery, especially its top, which may have traces of electrolyte.
- Check electrolyte level and density. If necessary, bring the electrolyte level to normal.
To charge the battery, use the charger or charger according to the instructions.
Remove all plugs of cans and connect the charger wires to the battery terminals, observing the polarity; then turn on the charger.
Set the charging current to 0.1 of the battery capacity (for a battery with a capacity of 36 Ah - 3.6 A; for a battery with a capacity of 44 Ah - 4.4 A, etc.). During charging, periodically adjust the charging current.
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.
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.
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, pump out a part of the electrolyte with a hydrometer and add the same amount of electrolyte with a density of 1.40 g/cm3 (tab. 6). 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.
