1. In winter conditions, when the battery operates under high loads during cold engine starts and most of the electrical equipment is constantly running, it is recommended from time to time to fully charge the battery from an external source with a current of 3.5-4 A.
2. Charging with such a current is carried out until there is no increase in density within four hours.
3. It is also possible without any risk to leave the battery overnight for recharging with a small current of 1.5 A using a charger.
4. It is not recommended to resort to «forced» charging, which allegedly restores battery power within 1-2 hours, tk. this can seriously damage the battery plates due to overheating.
5. When charging the battery, make sure that the temperature of the electrolyte does not exceed 40°C.
