B. Regular check
1) At the time of a second periodical check OR AFTER A MAXIMUM OF SIX
MONTHS, do this battery test (also do the steps given in paragraph
2.A):
- Discharge the remaining capacity at 16 amps down to a voltage of
20 volts at the battery terminals.
- Measure the time from the start of discharge to the time when the
voltage is 20 volts.
- Connect a resistor of approximately 1 Q across each cell and
continue to discharge. Resistors with crocodile clips attached to
their leads can be easily attached to the cell terminals.
- Let the resistors stay in position for the night.
2) Remove all resistors, charge the battery (Refer to "DESCRIPTION
AND OPERATION" for a fully discharged battery).
- Adjust the electrolyte level in the cells (Refer to paragraph
2.A (1)). Then measure the voltage of each cell during the last
hour of the charge. Also write the quantity of distilled water
added to each cell.
- Immediately after the charge and the level adjustment, discharge
the battery again at 16 amps down to 20 volts ; measure the
terminal voltage of each cell.
Write the time that is necessary
for this second discharge.
- Results of the above tests:
The battery operates correctly if:
- The time necessary for the first discharge (paragraph 2.8 (1) is
more than 30 minutes
- The time necessary for the second discharge (paragraph 2.B (2)) is
not less than 51 minutes
- The voltage of each cell measured during the last hou
charge at 1.6 amps is not less than 1.50 volt (Precis
r of the
ion 0.5%)
- The quantity of distilled water added to each cell 's
approximately equal to or less than 20 cm3 (1.23 in
