Operating hints
• Before removing the battery
terminals
turn off the device.
• During the loading process
explosive gases
can be generated,
therefore
fire,
sparking
etc. should be avoided!
• The red battery terminal has to be connected to the positive pole and the black battery terminal to the minus pole – Do not mix them up!
• NEVER use the booster if the charging cables or the battery terminals are damaged! Do not
shake it or push it during loading.
• NEVER try charging a frozen battery!
• Use only the fuses that are available in the booster on delivery – NEVER install greater fuses.
• Clean the battery carefully before loading and check the battery voltage.
• Please note that the connected battery
is allowed to have
min. 50Ah and max. 750Ah
(Booster 430) or 800Ah (Booster 630).
Operating principle
W
hen the battery is charged
, the charging current is dependant on the battery type; generally it is
ca. 10% above the max. current of the battery.
Loading time
The loading time depends on the battery. An approximate formula is
Loading time = Battery capacity / charging current
During the charging process the charging current continues to drop so that the expected charging time
will be longer than min. ¼. The battery charger can load one or more batteries at the same time– the
charging time will be longer then.
If you want to start a vehicle with a booster, please note:
1. If it is a big engine it is better to carry out a fast charging of15 minutes before you start it.
2. If you want to start a diesel engine, have your heater plugs preheated before you try to start the
engine.
Connect the red battery terminal with the plus and the black battery terminal with minus pole. Do not
mix them up!
