Charging a vehicle battery

First read and observe the introductory information and safety warn-
ings on page 215.
A properly charged vehicle battery is essential for reliably starting the engine.
›
Switch off the ignition and all of the electrical components.
›
Only when performing a "quick-charge", disconnect both battery cables (first of
all "negative", then "positive").
›
Attach the terminal clamps of the charger to the battery terminals (red = "posi-
tive", black = "negative").
›
Plug the mains cable of the charger into the power socket and switch on the
device.
›
After charging has been successful: Switch off the charger and remove the
mains cable from the power socket.
›
Only then disconnect the charger's terminal clamps.
›
Reconnect the cables to the battery (first of all "positive", then "negative").
It is not necessary to disconnect the cables of the battery if you recharge the ve-
hicle battery using low amperages (for example from a mini-charger). Refer to the
instructions of the charger manufacturer.
A charging current of 0.1 multiple of the total vehicle battery capacity (or lower)
must be used until full charging is achieved.
It is necessary to disconnect both cables before charging the battery with high
amperages, so-called "quick-charging".
The vent plugs of the vehicle battery should not be opened for charging.
Replacing the vehicle battery
When replacing a battery, the new vehicle battery must have the same capacity,
voltage, amperage and be the same size. Suitable vehicle battery types can be
purchased from a specialist garage.
We recommend having the battery replaced by a specialist garage, where the
new vehicle battery will be installed properly and the original battery will be dis-
posed of in accordance with national regulations.
WARNING
"Quick-charging" the vehicle battery is dangerous and requires a special
charger and specialist knowledge.

General Maintenance
CAUTION
On vehicles with the START/STOP system, the pole terminal of the charger must
not be connected directly to the negative terminal of the vehicle battery, but only
to the engine earth » page 236, Jump-starting in vehicles with the START-STOP
system.
Note
We therefore recommend that vehicle batteries be rapid charged by a specialist
garage.
