PLYMOUTH SERVICE MANUAL
26. SERVICING BATTERIES.
193642
( 1)
Maintain the proper electrolyte
level by adding pure distilled water or any
water wh!ch is odorless, tasteless, colorless
and suitable for drinking, to each cell until
the solution is
%
inch above the plates.
( 2)
On batteries with ustar" level indi-
cators, fill until the solution reaches the star
level.
( 3)
On batteries with special vent
plugs, fill after removing the filler plugs and
attaching them to the vents. Fill each cell
to the top of the filler plug opening, then re-
move the plugs from the vents, and the elec-
trolyte will drop to the proper level which
is
%
inch above the top of the plates.
( 4)
Inspect battery level at least once
a month or every 1000 miles and fill as di-
rected on battery cover or until the solution
is % inch above the plates.
( 5)
Do not overfill or fill too fre-
quently.
( 6)
Check the state of charge of the
battery periodically with a hydrometer. The
following hydrometer readings show the
charge condition:
Fully charged .... 1.2 7 5 to 1.300
Half charged ..... 1.2 2 5
Dangerously low .. 1.150
( 7)
A fully charged battery will not
freeze in temperatures ordinarily encoun-
tered, but a battery with 1.15 0 specific
gravity will freeze at 5 °F above zero, while
a battery with 1.100 specific gravity will
freeze at l8°F above zero. For this reason,
the battery should be kept fully charged.
( 8)
Keep the battery securely fas-
tened in its carrier and clean and dry the
battery at frequent intervals.
( 9)
Remove the terminals at regular
intervals and clean and inspect them thor-
oughly. When installing connections, tighten
the terminals securely at both engine and
battery ends.
(10)
A loose battery connection will
cause excessively high generator voltage,
which is likely to burn out light bulbs, pit
and burn distributor breaker points and
cause damage to the generator and other
electrical equipment.
