Check the electrolyte level and add distilled water,
as necessary to raise the electrolyte to each cell's
MAX. level.
Check the battery for proper charge by taking an
electrolyte S.G. reading. If the reading is 1.22 or
less, as corrected to 20° C (68° F), it means that the
battery is still in a run-down condition and needs
recharging.
NOTE:
First, remove the
8
lead wire.
RECHARGING OPERATION
BASED ON S.G. READING
To read the S.G. on the hydrometer, bring the
electrolyte in the hydrometer to eye level and read
the graduations on the float scale bordering on the
meniscus (curved-up portion of electrolyte surface),
as shown in figure.
Check the reading (as corrected to 20°C) with
chart to determine the recharging time in hour by
constant-current charging at a charging rate of 1.4
amperes (which is tenth of the capacity of the
present battery).
Be careful not to permit the electrolyte tempera-
ture to exceed 45°C (113° F), at any time, during
the recharging operation. Interrupt the operation,
as necessary, to let the electrolyte cool down.
Recharge the battery to the specification.

CAUTION:
1.28 at 20° C (68° F)
Constant-voltage charging, otherwise called
"quick" charging, is not recommendable for
it could shorten the life of the battery.
