Charging the battery
WARNING
Remove the cables from the positive and negative terminals of the battery before setting
the battery to charge. Otherwise, abnormal voltage may be applied to the alternator and
may damage it.
WARNING
Do not connect the connection cables to the terminals in reverse polarity. For example,
never connect the negative terminal on one machine to the positive terminal on the other
machine. A polarity reversal may damage the alternator.
• When the battery is charging, remove all the plugs to release the gases generated.
• If the battery overheats (the electrolyte temperature exceeds 45°C), stop the operation.
• Stop the charging operation as soon as the battery is charged. If you continue, the following
faults may occur :
– battery overload
– reduction in the battery electrolyte
– battery failure
• The battery must only be handled once the cables have been disconnected (except for
checking the level of electrolyte and the specified electrolyte density measurement).
Connecting
