Charging the battery
Only use chargers with a maximum charging
voltage of
14.8 V. The battery connecting ca-
bles do not need to be disconnected. Do not
open the battery when charging.
Read all of the manufacturer's instructions for
the charger before charting the battery.
It is not necessary to remove the battery from
the engine compartment, and it is also not
necessary to disconnect the cables.
Normally, a battery should be charged at no
more than 10 percent of its rated capacity.
For example, a charging current of 4.5 amps
would be used on a battery rated at 4 5 Ah.
Rated capacity of the battery in your veh icle is
listed on the battery housing .
The battery caps shou ld
not be opened when
cha rging a battery.
_& WARNING
Charging a battery can be dangerous.
- Never charge a frozen battery. It may ex-
plode because of gas trapped in the ice.
Allow a frozen battery to thaw out first .
- Do not reuse batteries which were fro-
zen. They must be replaced. 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 elec-
trical spark. Do not smoke. Hydrogen gas
generated by the battery is explosive.
- To reduce the danger of explosion, never
connect or disconnect charger cab les
while the charger is operating.
- Fast charging a battery is dangerous and
should only be attempted by a compe-
tent techn ician with the proper equip-
ment.
- Battery acid that may sp ill dur ing charg-
ing should be washed off with a solut ion
of warm water and baking soda to neu-
tralize the acid.
{[) Note
- Make sure that the gas venting hose is
always connected to the original opening
on the battery side. Otherwise gasses or
battery acid could leak out.
- Never use a fast charger as a booster to
start the engine. This will seriously dam-
age sensitive electron ic components,
such as contro l units, relays, radio, etc.,
as well as the batte ry charger.
- The vehicle may be optionally equ ipped
with a gel battery, wh ich can only be
charged at a const ant current-lim ited
voltage . To prevent damage to the bat -
tery and the electronics system, a gel
battery that is connected must under no
circumstances be charged with a quick
charger.
{!) Tips
- The vehicle battery must not be charged
with a standard small charger that plugs
into the outlet.
- Only charge the battery through the con-
nections in the engine compartment.
Battery replacement
The new battery must hove the some specifi-
cations as the old one.
