A discharged battery can freeze at tempera­
tures of on ly 32 °F (0 °C). Allow a frozen bat­
tery to thaw completely before attempting to charge it
c:> .&. However, we recommend not
using a thawed battery again because the bat- tery casing can
be cracked due to ice forma ­
tion and can leak battery acid.
Battery charging (Maximum charging rate
of 30 amps/14.8 Volt)
When charging at low voltages (e.g. with a
trickle charger), the battery cables do not
have to be disconnected first. The battery
caps should
not be opened when charging a
battery.
It i s not necessary to remove the battery from
the luggage compartment.
Fast charging the battery (charging rate
above 14 .8 Volts)
For technical reasons do not use a battery
charger that uses voltage greater than 14.8
Volts to charge your vehicle's battery.

- Always follow the operating instructions
provided by the battery charger manu­
facturer when charging your battery.
- Never charge a frozen battery. It may ex­
