A d ischarged battery can freeze at temperatures
of only 32 F

thaw complete ly before attempting to charge it
~ .&. . However, we recommend not using a
thawed battery aga in 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 trickl e
charger ), the battery cab les do not have to be
d isconnected first. The battery caps shou ld
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 nec ­
essary to disconnect the cables .
Fast charging the battery (charg ing rate
a bo ve 14.8 Volt s)
F or technical reasons do not use a battery charg­
er that us es voltage greater than 14 .8 Volts to
charge your vehicle's battery.
A WARNING
Charging a battery can be dangerous.
- Always fo llow the operating instructions
provided by the battery charger manufactur­
er when charging y our battery.
- Never charge a frozen battery. It may ex­
plode because of gas trapped in the ice. Al­
low a frozen battery to thaw o ut 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. Hyd rogen gas generat ­
ed by the battery is explos ive .
- To reduce the danger of explosion, never co nnect or disconnect cha rger cables while
the cha rger is operating .
- Fast charg ing a battery is dangerous and
should only be attempted by a competent
tec hnician with the p roper equipment .
- Battery acid that may spill during charg ing
should be washed off w ith a so lution of
wa rm water and baking so da t o n eutrali ze
t he a cid .
Checking and Fillin g
(D Note
Never use a fast charger as a booster to start
the engine . This will ser iously damage sensi­
tive electronic components, s uch as control
units, relays, radio, etc., as well as the battery
charger .
Battery replacement
