Battery - Mercedes-Benz 1985 380SE Owner's Manual

Electrical System

Battery

Check fluid level in each cell appro­
ximately every four weeks, and more
frequently during the summer and in
hot climates.
Refill battery only with distilled
water. Do not use metal funnels or
push through the overfill-protection
diaphragms in filler holes.
The battery is completely filled when
the water stops draining through the
overfill-protection diaphragm.
To check the battery charge with a
hydrometer, push its tip through the
overfill-protection diaphragm and
take the electrolyte sample.
Coat battery terminal clamps with
acidproof grease. Keep battery
clean and dry.
The service life of the battery is also
dependent on its condition of
charge. It must be maintained suffi­
ciently charged for the battery 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 battery with a battery
charger when it is disconnected
from the vehicle electrical circuit.
Warning!
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, if neces­
sary seek medical help.
A battery will also produce hydrogen
gas, which is flammable and explo­
sive. Keep flames or sparks away
from battery, i.e. improper connec­
tion of jumper cables, cigarette
smoking, etc..
While the engine is running the
battery terminal clamps must not be
loosened or detached as otherwise
the alternator and other electronic
units would be damaged.
Only tow vehicle with the battery
connected.
