WARNING: This page is about a different car, the 2016 BMW Z4, 2015 BMW Z4, and 2014 BMW Z4. However, it is still accessible from the selected car via links, so may be relevant.

WARNING: Read and comply with SAFETY INFORMATION FOR HANDLING VEHICLE BATTERY .

IMPORTANT: Lead-acid battery, AGM battery:
To prevent the intelligent battery sensor from malfunctioning, use the charging points in the engine compartment.

Observe instructions on INTELLIGENT BATTERY SENSOR/BATTERY ELECTRONICS .

Pay attention when charging the lithium ion battery!

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

This excessive charging voltage may in some cases result in that the separating switch of the lithium ion battery will be opened. This does not damage the lithium ion battery . The separator switch will close again when a charging voltage of < 14 V is applied at the battery terminals.

Before charging a lithium ion battery, adjust the charging voltage of existing charger adapters once.
