H. Charge battery until all cells are
gassing freely
voltage and specific
electrolyte are constant over three
successive readings taken at one-
hour intervals. (This procedure may
take 18 - 24 hours with a constant
current charger.) During the period
of charging,
temperatures shall be maintained
between 60F and 110F (15.6C
and 43.3C). Charge rate is 3 amps.
Reduce rate by 1/2 when cells start
gassing.
I. When the battery is completely
charged, the specific gravity should
read between 1.285 and 1.295. At
this point, if electrolyte level needs to
be adjusted,

BATTERY OPERATION

Battery operation is controlled by a battery
switch, placarded BATT-ON-OFF, located
on the switch panel in the cockpit.
battery is capable of assuming the complete
electrical load for a limited time at 70 amps
max.
The batteries are located on the battery
plate assembly on the engine mount aft of
the engine. They are installed with two-
battery hold down rods through the battery
cover. The battery case is vented overboard
to dispose of any electrolyte or hydrogen
gas fumes discharged
charging operation. Air enters the battery
compartment from an air scoop located in
the left cowl shin skin, circulates throughout
the battery compartment, and exists through
a vent in the battery and drains overboard
through a vent located on the belly skins.

BATTERY REMOVAL

A. Verify that the BATT-ON-OFF switch is
off. Disconnect external power.
B. Remove R.H. aft cowl skin.
C. Disconnect the battery and remove all
safety wire.
D. Disconnect vent tubes.
E. Remove nuts from battery hold down
