Checking and Filling
A discharged battery can freeze at temperatures
of only 32 F
0
(0 °C). Allow a frozen battery to
thaw completely before attempting to charge it
¢ & . However , we recommend not using a
thawed battery again because the battery casing
can be cracked due to ice formation 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 trick-
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 battery (charging rate
above 14 .8 Volts)
For technical reasons do not use a battery charg-
er that uses voltage greater than 14.8 Volts to
charge your vehicle's battery.
.&_ WARNING
Charg ing a battery can be dangerous.
- Always follow the operating instructions
provided by the battery charger manufactur-
er when charging your battery.
- Never charge a frozen battery. It may ex-
plode because of gas trapped in the ice. Al-

- Do not reuse batteries which were frozen.
The battery housing may have cracked and
weakened when the battery froze.
- Charge the battery in a well ventilated area.
Keep away from open flame or electrical
spark. Do not smoke. Hydrogen gas generat-
ed by the battery is explos ive.
- To reduce the danger of explosion, never
connect or disconnect charger cables while
