OBSERVE INSTRUCTIONS ON INTELLIGENT BATTERY SENSOR/BATTERY ELECTRONICS .
NOTE:
Use BMW-recommended charging computers to charge the battery.
Pay attention when charging the lithium ion battery!
Existing chargers that are designed for the lead-acid or AGM battery generate a charging voltage that is too high for the lithium-ion battery.
If the charging voltage is too high, the electronic disconnect switch of the Li-ion battery can open, which generates a CCM message in the instrument cluster.
Before charging a lithium ion battery, adjust the charging voltage of existing charger adapters once.
