A properly charged vehicle battery is essential for reliably starting the engine.
It is not necessary to disconnect the battery cables if you are recharging the vehicle battery using low amperages (for example from a mini-charger). Refer to the charger manufacturer's instructions.
A charging current of 0.1 multiple of the total vehicle battery capacity (or lower) must be used until full charging is achieved.
Both cables must be disconnected before charging the battery with high amperages, known as “rapid charging”.
The vent plugs of the vehicle battery should not be opened for charging.
WARNING
“Quick-charging” the vehicle battery is dangerous and requires a special charger and specialist knowledge.
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 165, Jump-starting in vehicles with the START-STOP system.
Note
We therefore recommend that vehicle batteries be rapid charged by a specialist garage.
Replacing
The new vehicle battery must have the same capacity, voltage, current and the same size as the original battery. Suitable vehicle battery types can be purchased from a specialist garage.
We recommend that the battery is replaced by a specialist garage, where the new vehicle battery will be installed properly and the original battery will be disposed of in accordance with national regulations.
