(6) Adjust charging amperage. Use the ammeter charging rate control knob to
adjust ammeter amperage as near as possible to 5 amperes for each battery

(a) Check the cables on each battery showing low voltage. Check the
location where the cable goes into the charger.
(b) If any cable plug-in does not make connection to a receptacle, try
interchanging cables at the charger. It this is not successful with any
given cable connection, charger is defective. Turn in charger.
(7) Use the following as a guide to recharge 12 volt lead-acid military batteries.
a. Pretest Battery (ies).
(1) Check all batteries for voltages and/or specific gravity readings. Use
the hand held tester (Item 20, Appx. B) to check for voltage and Load
testing and/or use the Optical (Item 21, Appx. B) or hydrometer
(Item 19, Appx. B) for specific gravity readings.
(2) For open circuit voltage (OCV) you may also use a multi-meter
(3) Group batteries for charging as follows.
