Battery Service - Piper Cherokee Arrow II Pilots Operating Manual

For maximum service from the tires, keep them inflated to the proper pressure of 30 psi for
nose tire and 27 psi for main tires. Interchange the tires periodically for even wear. All wheels
and tires are balanced before original installation, and the relationship of tire, tube and wheel
should be maintained upon reinstallation. In the installation of new components, it may be
necessary to rebalance the wheels with the tires mounted. Unbalanced wheels can cause extreme
vibration in the landing gear.
BATTERY SERVICE
Access to the 12-volt 25 ampere-hour battery is gained through the baggage compartment.
It is located just aft of the baggage compartment. The battery container has a plastic drain tube
which is normally closed off. This tube should be drained periodically to remove battery acid
which may have collected in the tube.
The battery fluid level must not be brought above the baffle plates. It should be checked
every 30 days to determine that the fluid level is proper and the connections are tight and free
of corrosion.
If the battery is not properly charged, recharge it starting with a rate of four amperes and
finishing with a rate of two amperes. The battery should be removed from the airplane for
charging, and quick drains are not recommended.
The external power receptacle, if installed, is located on the right side of the fuselage aft of
the baggage compartment.
Refer to the Arrow I1 Service Manual for battery servicing procedure.
WINTERIZATION
For winter operation, a winterization kit is installed on the inlet opening of the oil cooler
plenum chamber. This kit should be installed whenever the ambient temperature is 50°F or
less. When the kit is not being used, it can be stowed on a bracket provided for this purpose on
the outboard side of the oil cooler plenum chamber.
