However, we recommend not using a
thawed battery aga in because the battery cas ing
can be cracked due to ice formation and can leak
battery acid.
Batte ry charging (Maximum charg ing rate of
30 amps / 14 .8 Volt)
When charging at
low
voltages (e.g. with a t rick-
le charger), the battery cables do not have to be
disconnected first . The battery caps should
not
be opened when charging a battery .
It is not necessary to remove the battery from
the luggage compartment,
and it is also not nec-
essary to disconnect the cables.
Fast charging the batt ery (charg ing rat e
above 14 .8 Volt s)
For techn ical reasons do not use a battery charg-
er that uses voltage greater than 14.8 Volts to
charge your veh icle's battery.
