COMPONENT MAINTENANCE MANUAL
1606-l
- Battery not fully discharged and discharge condition unknow.
- Discharge the remaining capacity at 1ClA (16 amps) down
to 20 volts. Then charge again as above.
- The battery can also be charged at one of the constant
current values given in section 2 (2). Do this procedure
until you get the correct voltage at the battery
terminals (30, 31, or 31.4 V).
- Constant voltage charge
You can charge the battery with a constant voltage source
(you can use an aircraft generator that has a voltage
regulator).
At the usual temperature of +20°C (+68"F), adjust the
regulator to 28.5 volts (precision 0.5%) and charge the
battery for 4 to 5 hours.
B. Discharge
The specified capacity (ClAh) of the battery gives a discharge time
of 1 hour ;
when fully charged,
the battery can thus supply a current
of 16 amps for one hour. But the battery can supply currents that are
much higher than the specified discharge, for short times and without
damage.
For example, a battery with a specified capacity of 16Ah can
supply peaks of current that can be twenty-five times the usual
capacity.
C. Precautions
- You must usually supply regular current and do regular maintenance.
Thus it is only necessary to use these precautions to get correct
operation of the battery:
- Do not install the battery in an aircraft location which is too hot
- Carefully obey the instructions that give the procedure to get a
good flow of air
- Do a charge level check regularly.
Charge the battery on the ground
when the discharge is not caused by an incorrect adjustment of the
recharger.
- Regularly do these checks:
- Electrolyte level (specially when the weather is hot)
- Tightness of the connection nuts
- Adjustment of the recharger.
