Charging The Battery
- Danger of fire or explosion
- → Avoid contact with hot parts or sources of ignition.
- → Use suction to remove ignitable vapours.
- → Attach warning sign in a clearly visible position.
- → Contain leaked media using non-flammable absorbent material and put it in a container designed for this purpose for disposal in accordance with local requirements.
- → Secure collection containers/vessels to prevent them from tipping over.
Information
- A battery charger is required.
- Read operating instructions for the battery charger.
- The battery must have a minimum temperature of 0°C.
- If possible, do not rapid-charge batteries as this can damage them.
- If exhaustively discharged batteries are charged quickly, they will not take up a charge current or they will be identified too early as full due to the so-called "surface charge".
- Switch off battery charging device.
- Switch off ignition and keep transmitter key outside of the transmission range (at least 2 m).
NOTIFICATION
A battery charger for providing an external power supply or for jump-lead starting is connected directly to the battery in the vehicle.
- Damage to battery sensor
- Battery sensor sends incorrect battery values to the vehicle electrical system.
Always connect a battery charger for providing an external power supply or for jump-lead starting to the defined connections in the engine compartment.

- Connect battery charger cables to the external power supply points.
- Set the charge current on the battery charger according to the battery capacity.
- Switch on battery charger.
Procedure for charging exhaustively discharged batteries:
Batteries that have not been used for a long time discharge automatically.
A battery is exhaustively discharged if the open-circuit voltage has dropped to below 11.6 V, see Open-circuit voltage measurement.
In exhaustively discharged batteries, the battery acid (sulphuric acid and water mixture) consists of virtually only water, as the sulphuric acid proportion is considerably reduced.
Exhaustively discharged batteries sulphatise, i.e. the entire plate surfaces of the batteries harden.
Totally discharged batteries must not be charged and must be replaced.
- Charge the battery.
