You can use a normal charger to charge the battery. The battery can also be charged with a special fast charger. Charging current should be between 3 and 25 A; charging voltage - from 14 to 15.5 V.
Charge the battery only outdoors or in a well-ventilated area.
If the electrolyte level is low, e.g. during operation in hot weather, top up with distilled water.
If the vehicle has not been driven for more than 6 weeks, remove the battery and recharge it. The optimum battery storage temperature is between 0 and 27°C. At these temperatures, battery self-discharge is minimal. After three months of storage, the battery must be recharged.
Regularly clean the battery contacts and lubricate them with petroleum jelly or special protective grease.
Starting devices can only be used in exceptional cases, because. a very large current will flow through the battery for a short time. If the battery has been stored for a long time, it should not be charged with a fast charger.
Attention: Do not turn on the starting device without starting the starter at the same time.
