COMPONENT MAINTENANCE MANUAL
1606-l
(2) Ground charge
Do all battery maintenance or overhaul steps in a workshop.
WARNING: REMOVE THE COVER TO CHARGE THE 1606-l TYPE BATTERIES ON
THE GROUND. THIS IS TO MAKE SURE THAT GAS WILL NOT
COLLECT IN THE BATTERY BOX.
- Constant current charge
- Battery fully discharged:
To charge a fully discharged battery, do one of these
procedures:
- Charge at 0.1 CIA (1.6 amps) until the battery voltage is an
average of 1.5 volt for each cell (30 volts for a 20-cell
battery).
Then continue to charge at this same current rate
for 4 more hours. When you do this procedure, the total
charge time must be between 14 hours (minimum) and 16 hours
(maximum).
or
- Charge at 0.5 C A (8A) for not less than 2 hours. It is
possible that t e battery voltage is not an average of 1.55 il
volt for each cell (31 volts for a 20-cell battery) after
this time. Then continue to charge at this current rate
until you get the correct voltage. But do not charge at
this rate for more than 2 hours and 30 minutes (refer to
the NOTE). When you get an average of 1.55 volt, charge at
0.1 ClA (1.6 amps) for 4 more hours.
or
- Charge at ClA (16 amps) for not less than 1 hour. It is
possible that the battery voltage is not an average of 1.57
volt for each cell (31.4 volts for a 20-cell battery) after
this time. Then continue to charge at this current rate
until you get the correct voltage. But do not charge at
this rate for more than 1 hour and 15 minutes (refer to the
NOTE). When you get an average of 1.57 volt, charge at 0.1
CIA (1.6 amps) for 4 more hours.
NOTE: If the battery voltage does not increase sufficiently
during the maximum charge time: Refer to "TESTING
AND FAULT ISOLATION"..
