When charging the starter battery with an external charger, proceed as fol-
lows:
Turn off the vehicle engine.
Switch off the 12 V power supply on the panel. The indicator lamps or
the displays on the panel go out.
Switch off all gas appliances, all gas isolator taps and close the regula-
tor tap on the gas bottle.
Disconnect the starter battery from the vehicle (e.g. remove the battery
terminals). There is a danger of short circuit when disconnecting the bat-
tery poles. For this reason, first disconnect the negative terminal and
then the positive.
Check that the external charger is turned off.
Connect the external charger to the starter battery. Pay attention to the
polarity: First connect the positive terminal "+" to the positive terminal of
the starter battery, then connect the negative terminal "–" to the negative
pole of the starter battery.
Switch on the external charger.
See the instructions for use of the connected charger for information
concerning charge period required for the battery.
See the specifications on the battery for information concerning its
strength.
Disconnect the charger in reverse order (the negative terminal first).
Connect the battery terminals again (first the positive terminal).
This section contains instructions on the storage of the starter battery.
Store the disconnected battery in a cool and dry place.
Connect the disconnected battery to a charger for 24 to 48 hours every
4 to 6 weeks.
If the battery remains connected during a lay-up, it may become neces-
sary to recharge already after 14 day or in even shorter intervals.
If there is an "intelligent" charger with float charge functionality, have the
charger connected to the battery and switched on over the entire lay-up
time.
