Battery - Mercedes-Benz 300 SL Owner's Manual

Battery

The maintenance-free battery is located
in the trunk behind the right-hand cover
panel.
The service life of the battery is
dependent on its condition of charge.
The battery should always be
sufficiently charged to last an optimum
length of time.
Therefore, we recommend that you
have the battery charge checked
frequently if you use the vehicle mostly
for short distance trips, or if it is not
used for long periods of time.
Only charge a battery with a battery
charger after it has been disconnected
from the vehicle electrical circuit.
When removing and connecting the
battery, always make sure that all
electrical consumers are off and the
key is in steering lock position 0.
While the engine is running the battery
terminal clamps must not be loosened
or detached, otherwise the alternator
and other electronic components would
be damaged.
Warning!
Never lean over batteries while
connecting or jump starting, you
might get injured,
Battery fluid contains sulfuric acid.
Do not allow this fluid to come in
contact with eyes, skin or clothing.
In case it does, immediately flush
affected area with water and seek
medical help.
A battery will also produce hydrogen
gas, which is flammable and
explosive. Keep flames or sparks
away from battery, avoid improper
connection of jumper cables,
smoking, etc..
Batteries contain enough
electricity to burn you. Never touch
uninsulated battery connections.
