General notes

Attention! 

Risk of damage!

The charging voltage that is generated by existing chargers that are designed for the lead-acid battery or AGM battery is too high for the lithium ion battery.

This excessive charging voltage will result in damage to the lithium ion battery!

Therefore, the software for existing chargers must be updated prior to charging a lithium ion battery!

(Information regarding software updates: Contact the workshop equipment hotline)

Attention! 

The maximum voltage is 14.4 V. This voltage must not be exceeded. The voltage for charging procedure is 14.0 V.

Attention! 

Use chargers enabled by BMW (e.g. Deutronic charger DBL1200 and 1600).
