Battery charging (Maximum charging rate of 30
amps/14.8 Volt)
Wh en charging a t /ow voltages (e.g. with a trickle charger), t h e
battery cables do not have to be disconnected first. The battery caps
should not be opened w hen c ha rging a ba ttery.
It is not necessary to remove the battery from the luggage compart ­
