c. As a pre-caution ensure that all batteries to be charged have the same rated
voltages, and that the constant charging voltage is matched to this rated
voltage. The charging voltage must be selected as follows:
13.5 volts to 14.5 volts for batteries rated at 12 volts
NOTE
Note the total loading current of the charger. When it
registers to 1% of the total capacity of the connected
batteries, then all the batteries are fully charged.
5-8 Vehicle Power System Charging.
a. By vehicle power system charging we mean the recharging via on-board power
systems, e.g., via the external starting sockets of tactical vehicles (Nato
Connector).
b. This form of recharging is possible without taking special measures. However,
it is necessary for the battery voltage to match the vehicle's system voltage as
follows:
(1) 12 volt batteries can be charged from 12 volt vehicle systems.
(2) 24 volt batteries and battery sets consisting of 12 volt batteries in series-
parallel can be charged from 24 volt vehicle systems.
5-9 Withdrawal From Use and Storage.
a. Sealed lead-acid batteries have very low self-discharge rates.
b. They must be stored in the fully charged condition.
c. No special storage conditions are needed for these batteries, although the
storage room should be cool and dry.
