COMPONENT MAINTENANCE MANUAL
1606-l
CHECK
1. Regular checks
You must do the checks which are necessary to use the SAFT 1606-l
batteries in flight and on the ground.
But you must also do these
maintenance steps during operation:
- Periodical check (in a workshop):
adjustment of electrolyte levels
- Regular check (in a workshop):
electrical treatment, adjustment of
electrolyte levels, and capacity test.
2. Maintenance steps in workshop
A. Periodical check
Periodically (at flight hour intervals such that the allowable water
consumption is not exceeded):
- Clean the battery (See "CLEANING")
I -
Adjust the electrolyte level (Refer to (1)).
(1) Charge of the battery and adjustment of the electrolyte level:
- Discharge the remaining capacity at 16 amps down to a voltage of
20 volts at the battery terminals.
- When the battery temperature is +2O"C to +25OC (+68OF to +77OF)
(usual temperature range),
charge the battery (Refer to one of
the procedures given in
"DESCRIPTION AND OPERATION" for a fully
discharged battery).
- During the last hour of the charge (while the charge current
continues to flow), adjust the level of the electrolyte in the
cells. Then measure the voltages of each cell (precision 0.5 %).
Write the quantity of water that is added to each cell.
- The electrolyte level changes with the battery charge. Thus you
do not get the maximum level until the battery is fully charged.
The level changes as if the plates absorbed a part of the
electrolyte during the discharge and released it during the
charge.
