Battery
Do not short circuit the battery termi-
nals. This creates a risk of personal in-
jury from high-voltage sparks.
A highly-explosive gas is
generated when the battery is
charged.
If you happen to get acid in
your eyes, rinse thoroughly for
15 minutes with clear water.
Consult a physician immediately. If you
get acid spray on your skin or clothing,
rinse with plenty of water. If electrolyte
is accidentally ingested, consult a phy-
sician immediately.
In order to protect the battery
case from ultraviolet radiation,
do not place it in direct sunlight.
A discharged battery can freeze. Store
the battery in areas where temperature
remains above freezing.
Car care
The battery is completely maintenance-
free, that is, the original electrolyte will
normally last for the service life of the
battery.

Charging the battery
Charge the battery in the vehicle only
when the engine is off. Charge the bat-
tery using the supplementary positive
terminal and ground (terminal) in the en-
gine compartment (refer to "Jump-start-
ing" on page 179).
On the BMW 750iL, there is an auto-
matic switch between the two batteries
during charging.
Before performing any work on
the electrical system, disconnect
the cable from the negative terminal. If
you do not, short circuits can create the
risk of fire or personal injury.
If a jump start is necessary, connect the
cables only to the auxiliary terminal for
jump starting and a ground in the en-
gine compartment in order to avoid
damage to the batteries (refer to
"Jump-starting" on page 179).<
