Battery charging
If a normal or quick charger is used to charge the battery, the battery must be disconnected from the vehicle electrical
system and removed. This prevents damage to paintwork and upholstery.
Ideally, battery charging is performed with BMW-approved charging computers, refer to
SI 2 03 98 350
and
SI 2 06 02 854
.
Important!
In order to prevent the intelligent battery sensor from malfunctioning, the charging terminals in the engine
compartment must be used without fail in vehicles from E60 and should be used if possible in other vehicles.
Important!
Before charging the battery while it is installed, first carry out a closed-circuit current test. If here the voltage
is 10 V or less, one or more of the cells may be faulty or the entire battery may already be damaged. In this
case, always remove the battery as escaping gases during charging could damage the interior equipment and
trim. Attempt to regenerate faulty cells with low charging current.
If necessary, open existing plugs on the individual cells.
