Battery - Mercedes-Benz 190 E2.3 1985 Owner's Manual

Battery

Check fluid level in each cell approxi­
mately every 4 weeks, and more fre­
quently during the summer and in hot
climates.
Refill battery only with distilled water.
Do not use metal funnels or push
through the overfill-protection dia­
phragms 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 acid-
proof grease. Keep battery clean and
dry.
The service life of the battery is also
dependent on its condition of charge.
It must be maintained sufficiently
charged for the battery to last an
optimum length of time.
Therefore, we recommend that you
have the battery charge checked fre­
quently 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 necessary seek medical
help.
A battery will also produce hydrogen
gas, which is flammable and explosive.
Keep flames or sparks away from bat­
tery, i. e. improper connection 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 con­
nected.
