Charge
CAUTION:
ATTEMPTING TO CHARGE BATTERIES WITH LOW
ELECTROLYTE LEVELS IN ANY CELL MAY CAUSE
PERMANENT DAMAGE TO THAT CELL.
NOTE:
The battery must be allowed to cool 1-2 hours before charging the
battery following a discharge procedure.
(1)
Remove the cover (8), pad (9) and formed insulator (10).
(2)
Loosen, but do not remove, all vent valves (1).
CAUTION
: CHECK INDIVIDUAL CELL VOLTAGES AT THE
BEGINNING OF THE CHARGE. IF ANY CELL
INDICATES AN IMMEDIATE VOLTAGE RISE ABOVE
1.50 VOLTS, ADD ABOUT 10 CC'S OF DISTILLED OR
DEMINERALIZED WATER THROUGH THE VENT
VALVE OPENING OF THAT CELL.
(3)
Charge using one of the two methods shown in Figure 104.
(4)
During the last 15 minutes of the overcharge cycle, adjust the electrolyte level.
(5)
Verify all cell voltages are above 1.50 V
