A discharged battery can freeze at temperatures
of only 32 F
0 (0 °C). A llow a frozen battery to
thaw comp letely before attempt ing to c harge it
¢
.&. . However, we recommend not us ing a
thawed batte ry again because the battery casing
can be cracked due to ice formation and can leak
battery acid.
Battery charging (Ma ximum charging rate of
30 amp s/ 14.8 Volt )
When charging at low voltages (e.g. with a trick­
le charger ),
the battery cables do not have to be
d isconnected first. The battery caps should
not
be opened when charging a battery.
It is not necessary to remove the battery from
the lu ggage compartment, and it is also not nec­
essary to disconnect the cables.
250
Fast charging the battery (charg ing rat e
abov e 14.8 Volts )
For technical reasons do not use a battery charg­
er that uses voltage greater than 14.8 Volts to
charge your veh icle's battery.
A 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
low a frozen battery to thaw out first.
- Do not reuse batteries which were frozen.
The battery hous ing 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 batte ry is explosive .
- To reduce the danger of explosion, never
connect or d isconnect charger cables while
the charger is ope rating .
- Fast charg ing a battery is dangerous and
should only be attempted by a competent
technician w ith the prope r equipment.
- Batte ry acid that may spill during charging
should be washed off w ith a so lution of
warm water and baking soda to neutra lize
the ac id.
{[) Note
Never use a fast cha rge r as a booster to start
the eng ine. This will se riously damage sensi­
tive elec tronic components, such as control
u nits, re lays, ra dio, e tc., as well as the ba ttery
charger.
