- When charging a battery installed in a vehicle, disconnect the negative wire from its terminals first, then the positive wire, to avoid damage to electrical equipment components.
- The charging current is usually ¹/10 part of the battery capacity.
- In case of fast charging due to lack of time, etc., the charging current should never exceed the battery capacity value indicated in amperes.
- The battery is fully charged if:
- the electrolyte density reached 1.250-1.290 and remains constant for an hour;
- the voltage of each battery bank has reached 2.5-2.8 V and remains constant for one hour.
