08 BATTERIES
All batteries are in the pylon area. Battery maintenance is covered in the Technical
Manual. It is necessary that the batteries be checked during the Preflight for security,
leakage, and any obvious mechanical defects. The state of the batteries electrically can be
determined from the voltmeter on the Pilots Main Electrical Panel. This should be checked
prior to engine start.
Two 24 Volt NiCad (d.c.) batteries are connected to give 24V d.c. Operating voltage. This
is a nominal voltage and can be up to 28 V D.C. when the batteries are fully charged and
the generators are charging.
If Ground Power is used for starting, the aircraft generators will then recharge the
batteries. To stop overloading (max 35 amps), the charge rate checked on the Pilots Main
Panel. The correct position on the selector switch must be used to obtain the charge rate
for each generator
