A discharged battery can freeze at tempera
tu res of only 32 F
0 (0 °C). Allow a frozen bat
te ry to thaw completely before attempting to
charge it¢ & . However, we recommend not
us ing a thawed battery again because the bat
tery casing can be cracked due to ice forma
t ion and can leak battery acid.
Battery cha rging (M ax imum charging rate
of 30 amp s/14.8 Volt )
When charg ing at low vo ltages (e.g. with a
t rickle cha rge r), the battery cables do not
have to be disconnected first. The battery
caps should
not be opened when charg ing a
battery.
It is not necessary to remove the battery from
the luggage compartment, and it is also not
necessary to d isconnect the cab les .
282 Emergency situations
@ Tips
-The discharged battery must be properly
connected to the vehicle's electrical sys
tem. When jump starting or charging the
battery, never connect the negative
ground cable to the battery negative
post because the battery manager sys
tem must be able to detect the battery's
state of charge . Always connect the neg
ative ground cable to the negative
ground post of the battery manager con
trol unit.
