8.3.1 Equalizing Charge Method
Constant voltage charging is the method for giving an equalizing charge. To perform an
equalizing charge, follow the procedure below:
1.
Determine the maximum voltage that may be applied to the system equipment.
2. Divide this voltage by the number of cells connected in a series.
This is the MAXIMUM VOLTS PER CELL to be used for the equalizing charge.
This number should NOT exceed 2.35 VOLTS PER CELL average.
3. Use Table 8.2 to determine the equalize charge time.
The times listed are the number of hours to charge the battery system AFTER the charge
current has been stabilized for three hours.
Stabilization occurs when the current level remains constant for three hours.
TABLE 8.2

During charge, if the cell/battery temperature exceeds 105˚F
(40˚C) stop the charge immediately and allow the temperature
to decrease below 90˚F (32˚C). Failure to follow this warning
may result in severe overcharge and damage to the cell/battery.
