Battery care and maintenance
WARNING: This page does not describe the selected car, but rather 7 other vehicles, including the 2016 BMW 760Li, 2015 BMW 760Li, 2014 BMW 760Li, 2013 BMW 760Li, and 2012 BMW 760Li. However, it is still accessible from the selected car via links, so may be relevant.
In low-maintenance batteries, check the electrolyte level at least once a year. If necessary, top up with distilled water up to the top marking.
The increasing number of electronic control units in the vehicle reduces the self-discharging time of the battery (even in standby mode). To maintain the battery service life and to avoid exhaustive discharging, recharge laid-up vehicles every 6 weeks at the latest. The time for self-discharging depends on vehicle type and equipment specification.
