COMPONENT MAINTENANCE MANUAL
NOTE
(5)
When the battery terminal voltage reaches 1.0 volts per cell (20.0 V), stop the
discharge, and record the time.
(6)
Interpretation of the Initial Discharge Results.
Based on the amount of time to discharge the first cell to 1.0 V the following
will apply:
(a)
The first cell discharged to 1.0 V in greater than the minimum time
listed in Figure 103, the battery and all cells are considered above rated
capacity. Proceed to with maintenance per Fig 102.
(b)
The first cell discharged to 1.0 V in less than the minimum time listed
in Figure 103, (indicating that there is a problem with at least one cell
in the battery). These results can be due to any of the following:
1
2
3
Proceed with Residual Discharge, Charge and Second Discharge as
described in TESTING and FAULT ISOLATION. Performing a deep
cycle will often correct any imbalance or temporary loss in capacity.

It is not a cause for concern if a cell goes to zero volts or
reverses polarity during the battery discharge. Simply short out
the cell's terminals for the remainder of the discharge.
The battery was used to power equipment after the last landing.
The battery cells have temporarily or permanently lost
electrochemical capacity.
A condition of cell capacity imbalance has developed.
It may be necessary to perform a deep cycle several
times to correct a severe imbalance or loss of capacity.
