process is entirely finished. This is the only way of gasses created during charging being able
to escape. A leak of minimal amounts of acid during charging is unavoidable.
Working principle
With the battery being charged, the charging current is dependant on its type. In general, it is around
10 % above the maximum current of the battery.
Charging time
The charging time depends on the battery. A rule of thumb is
During the charging process, the charging current continues to decrease, so that the calculated char-
ging time is at least ¼ longer. The battery charger can charge one or more batteries at the same time,
the charging time is then of course longer.
If you wish to start a vehicle with the booster, please note:
1. If the engine is bigger, it is better to boost charge it for 15 min prior to trying to restart it.
2. In case you wish to start a diesel engine, let the glow plugs preheat before trying to start the
engine.
For charging connect the red battery clamp with the positive terminal and the black clamp with the
negative terminal – never swap them!
Connect the connection cables of the charger with the battery. Connect the red cable (+) with the pos -
itive terminal (+) of the battery and the black cable (–) with its negative terminal (–). If the battery is still
in the vehicle, connect the black cable (–) with the engine block, functioning as grounding. Ensure that
the ignition and all electrical equipment parts are switched off. (If the vehicle has positive mass, con-
nect the red cable (+) with the engine block.)
