Disconnecting The Battery Terminals - Ford F-MAX User Manual

Batteries should always be charged as
required in order to have a long service life.
We advise you to use the circuit breaker
next to the battery tray to preserve the
service life of the battery when the vehicle
is not going to be used for a long time.
Check the battery voltage level if the
vehicle is parked for a long period of time.
12.2 V voltage level measured in a battery
indicates that battery charge level is too
low.
In this case, best method is to leave the
vehicle running in the shortest possible
time in order to charge the batteries.
