The use of tap water or water from other sources may introduce
chemicals, minerals or other undesirable elements which could
appreciably shorten battery life or make it unusable.
Allowing a completely discharged battery to stand for an extended
period of time (more than a week) may cause the plates to become
sulfated and hardened, thereby ruining the battery.
b. After a battery has been cleaned, serviced, and outer surface completely dried, place it in position for
charging, making sure all caps have been removed.
NOTE
When not clearly marked on the battery case, the voltage rating of a
lead-acid battery can be determined by counting the number of
battery cells: 24 volts, 12 cells; 12 volts, 6 cells; 6 volts, 3 cells.
NOTE
While the following instructions minimize the occasions for its use, a
hydrometer is the fundamental method of determining charge in a
battery. Use the hydrometer in all cases of doubt and also in the final
check to determine that the battery is fully charged and ready to
release for service. A hydrometer reading of 1.280 indicates a fully
charged battery. Readings below this value indicate the degree of
discharge. A hydrometer reading of 1.20 indicates the battery should
be recharged.
2.7. BATTERY CHARGING OPERATION (Lead-acid, 24 volts dc).
b. Check and make sure the circuit breaker switch for the selected 24 volt station is in the OFF position.
c. Select one of the battery charging cables (Figure 1-2) for use in connecting battery to Distribution Panel.
d. Connect red alligator clip on end of battery charging cable to positive (+) battery terminal, and then
connect black alligator clip to negative (-) battery terminal.
e. Insert polarized connector on battery charging cable into the selected polarized receptacle connector (9 or
16, Figure 2-1) and then twist the connector clockwise to securely lock in position.
NOTE
If the Distribution Panel is not already in service, it will be necessary
to place the POWER ON/OFF SWITCH (20, Figure 2-1) in the ON
position to apply operating power. While the Distribution Panel is in
continuous service, additional batteries may be connected to or
disconnected from the Distribution Panel with the POWER ON/OFF
SWITCH in the ON position provided the selected STA CIRCUIT
BREAKER is in the OFF position.
