SAFT
COMPONENT MAINTENANCE MANUAL
1606-l
- If the first discharge time is less than 30 minutes but the second
discharge time is correct: the battery is in good condition but
was not fully charged when removed from the aircraft.
This condition can be caused by:
- An incorrect charge in the aircraft
- And/or a discharge caused by an unusual operation of the battery
after landing.
Do a full overhaul of the battery (paragraph 3) if:
- The second discharge time is less the correct one or one cell has
a voltage of less than 1 volt (or incorrect polarity before 1 hour
of discharge)
- The voltage of each cell measured during the last hour of charge
at 1.6 amps is less than 1.50 volt
- The quantity of distilled water necessary for one or more cell(s)
is much higher or smaller than for the other cells.
NOTE: The consumption of water by a SAFT nickel-cadmium cell is in
proportion to the unwanted charge.
Thus, the consumption must be the same for all the 20 cells in the
battery.
The quantity of water necessary for one or more cell(s) (in the same
battery) can be much higher (or smaller) than the other cells. Then
there is a defect:
- High consumption is usually caused by a leakage.
- Low consumption is caused by a damaged separator.
- The consumption is incorrect when it is 25 % more or less than the
average.
