NOTE

Batteries will be charged in combinations of four using the following

procedure.

b. Charging- four 6-volt batteries in series (Figure 2-3).

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

terminal of battery "B", then

(2) Connect the negative terminal of battery "B" to the positive terminal of battery "C", then

(3) Connect the negative terminal of battery "C" to the positive terminal of battery "D".

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

to the negative terminal of battery "D".

NOTE

If the four 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.

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