thawed batte ry agai n because the batte ry casing
can be cracked due to ice forma tion a nd ca n leak
battery a cid.
Battery charging (Maximum charging rate of
30 amps /14.8 Volt )
When charging at low voltages (e.g. w ith a trickle
c harger ),
the battery cab les do not have to be
d isconnected first. The batte ry caps sho uld
not
be opened when charging a battery.
It is not necess ary to remove the ba tte ry from
t he luggage compa rtment.
Fast charging the battery (charging rate
above 14.8 Volts)
F or technica l reasons do no t use a ba ttery charg
e r that uses voltage grea ter than 14.8 Vol ts to
charge your vehicle's battery .
