POWER SOURCE CIRCUIT

l Inspection should be conducted with attention
paid to damage or abnormalties caused during
transportation (especially liquid leakage due to
cracks in the electrical container.
(2) Inspect the liquid level by removing the vent cap.
If any cell has a low liquid level, inspect for
breaks in the electrical container. If there are no
breaks, apply dilute sulfuric acid with the same
specific gravity as that of other cells.
(3) When more than two weeks have elapsed after
the inital charging, a supplementary charge should
be made to compensate for the self-discharged
electricity during the discharge period. It is desi-
rable that inspection be performed during supple-
mentary charge, level of cells and adjustment be
given to obtain equal levels; and records of vol·
toge, specific gravities, and ter:nperatures of cells
be taken upon completion of charging for reference
at a later date.
Caution required during use
( l l Periodical inspection should be performed. For
batteries employed in vehicles, inspection should be
performed weekly, twice a month, or every l 000
to 2000 km (620 to 1340 mil.
(2) Special attention is required during maintenance
concerning the liquid level surface. When the
liquid level is insufficient, distilled water should be
added so that the electrode plates and separators
are not exposed to air. On the transparent con-
tainer, the liquid level is indicated. Generally, the
liquid level should be from 10 to 13 mm (.39" to
. 51 "I above the separators. When the level is
lower and the electrode plates are 1:1xpased, the
exposed section is subject to oxidation ; white lead
sulfate is produced, capacity is decreased, and the
exposed section of the separators deteriorates in
performance causing internal shorts. This occurs
frequently and is the major cause of short battery
life.
(3) Proper charge should always be maintained. If a
battery is extensively used in a " low-charge "
state, sulfation results (sulfate cannot be returned
to its original properties). In such case, electrode
plates become curved and tend to cause shorts.
If a battery contains thin liquid at low specific
gravity due to over-discharge, the separators are
damaged. Therefore, it is necessary to discontinue
