BATTERY CHARGING OPERATION (12-Volt Batteries)

TM5-6130-301-13&P

2.9 BATTERY CHARGING OPERATION (12-Volt Batteries). The procedures in 2-8a through 1.

above, determine whether the battery is of high enough quality to accept a charge. If several 12-volt batteries

are to be charged, they may be charged using 24-volt, uncontrolled stations, as follows.

NOTE

Batteries will be charged in combinations of two, using this

procedure. Charge any odd battery on a controlled 12-volt station.

a. Perform the procedures of 2-8a through 1. above, for any even number of batteries.

b. Using an inter-battery jumper cable, connect the negative terminal of battery "A" to the positive terminal

of battery "B".

c. Connect the red clip lead of a charging cable to the positive terminal battery "A", and the black clip lead to

the negative terminal to battery "B".

NOTE

If the two batteries have different amp-hour ratings, the battery with

the lower rating will reach "soft" (or "hard") boiling before the other

in which case the early-boiling battery will control whether or not the

charging may be continued with this setup or whether the one

battery will have to be shifted to a controlled station.

d. Refer to paragraph 2-7 and follow the procedures for a 24 volt battery.

2-10. BATTERY CHARGING OPERATION (6-Volt Batteries). Although the Battery Charging

Distribution Panel is not specifically designed to charge 6-volt batteries, it is possible to do so using procedures

similar to those of paragraph 2-9. The more favored method for charging 6-volt batteries is to charge two

batteries in series using a 12-volt, controlled station (STA 1 or STA 4). However, four 6-volt batteries maybe

connected in series and charged using a 24-volt controlled or uncontrolled station.

NOTE

Batteries will be charged in combinations of two, using this

procedure.

a. Charging two 6-volt batteries in series (Figure 2-2).

(1) Using an inter-battery jumper cable, connect the negative terminal of battery "A" to the positive

terminal of battery "B".

(2) Connect the red clip lead of a charging cable to the positive terminal of battery "A", and the black clip

lead to the negative terminal of battery "B".

NOTE

If the two batteries have different amp-hour ratings, the battery with

the lower rating will reach "soft" (or "hard") boiling before the other

in which case the early-boiling battery will control whether or not the

charging may be continued with this setup or whether the one

battery will have to be shifted to a controlled station.

(3) Refer to paragraph 2-8 and follow procedures for a 12-volt battery,
