Battery Service
Access to the 24 volt Battery 1 is gained by removing the upper cowl.
It is mounted to the forward right side of the firewall. The battery vent
is connected to an acid resistant plastic tube that vents gases and
electrolyte overflow overboard.
The battery fluid level must not be brought above the baffle plates.
Until experience indicates a longer interval is justified, the battery
should be checked every 30 days to determine that the fluid level is
proper and the connections are tight and free of corrosion. Do not fill
the battery with acid use distilled water only.
If the battery is not properly charged, recharge it starting with a rate of
four amperes and finishing with a rate of two amperes in accordance
with Airplane Maintenance Manual (AMM) procedures. The battery
should be removed from the airplane for charging, and quick charges
are not recommended.
Battery 2 is a maintenance free, rechargeable, sealed, lead acid
batter. Mounted in the empennage just aft of bulkhead 222, there is no
need to check the specific gravity of the electrolyte or add water to
these batteries during their service life.
Refer to the Airplane
Maintenance Manual (AMM)
for Overhaul and Replacement
Schedule.
The external power receptacle is located on the left side of the
fuselage just aft of the firewall.
Refer to the Airplane Maintenance
Manual (AMM)
for battery servicing procedures.
