Charging Information -

Single Battery Charging

Charger should be capable of delivering at least 60 amp rate of charge with adjustable charge rate.

1) Connect battery to charger.
2) Connect charger to power source.
3) Set charger to high setting and charge battery.
4) Monitor battery hourly for spewing, gassing or heat above 125~F. If this occurs and charging voltage is 16 volts or below, replace battery. If over 16 volts, allow to cool, then resume charging at reduced rate to avoid these conditions.
5) Check charge acceptance hourly. If voltage is below 16 volts, continue charging. If 16 volts or above, check charge rate in amperes. If 5 amperes or above, continue charging. If below 5 amperes, battery is sufficiently charged.
6) Unplug charger, then disconnect from battery.
7) Remove surface charge. See "State of Charge Check".
8) Load test battery.


Important - Age, capacity, state of charge and type of batteries
vary. Closely monitor batteries during any charging procedure.

Important - Clean all terminals and make sure all electrical
connections are tight.

Important - Battery should be charged at room temperature. After
charging battery, follow the load test procedure.


For batteries which have discharged and remain uncharged for a long period of time, it will be necessary to first remove sulfation from the battery plates. First apply a high rate of charge (30 amps) for 1 to 1-1/2 hours observing the precautions in step 4 of "Single Battery Charging". Following this, apply approximately a 6 amp charge until 3 successive specific gravity checks at 1 hour intervals reveal no increase in specific gravity readings. (May take as much as 20 - 24 hours with a 6 amp charger).
