G. Clean and neutralize any spilled
electrolyte on battery.
H. Charge battery until all cells are
gassing freely and the charge
voltage and specific gravity of
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, the electrolyte
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, remove or add
electrolyte to proper level and
recharge for one hour.
1.285 - 1.295
CHARGED
1.275 or Less
RECHARGE
Gasses given off by a
battery under charging
conditions are flammable.
*NOTE*
For more detailed
instructions, see Gill Service
Manual.
SERVICING BATTERY INSTALLED IN
AIRCRAFT
The 24-volt battery is installed aft of the
engine on the engine mount lower
longerons and is accessible through the
removable cowling skins (see figure 4-8
&10-1 D). Check the battery electrolyte
level frequently, especially during hot
weather. If a visual check shows low cell
level, and no electrolyte is available at
this time, add distilled water to bring the
cell(s) up to the proper lever. (See
battery-servicing instructions)
BATTERY OPERATION
Battery operation is controlled by a
battery switch, placarded BATT-ON-
OFF, located on the switch panel in the
cockpit. The battery is capable of
assuming the complete electrical load for
a limited time at 70 amps max.
The battery is located on the battery
plate assembly on the engine mount aft
of the engine. It is installed with battery
hold down rods through the battery
cover. The battery case is vented
overboard to dispose of any electrolyte or
hydrogen gas fumes discharged during
normal charging operation. Air enters
the battery compartment from an air
scoop located in the right cowl shin skin,
circulates throughout the battery
compartment, and exists through the
vent in the battery case and drains
overboard through an outlet located on
the belly skin.
CAUTION
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
rods and remove battery from
compartment.
