MAINTENANCE MANUAL
I. Repairs, Storage, and Service Tips
The internal parts of the battery have been designed to wear at approximately the same rate,
making it uneconomical to replace any of the parts with new ones. Replacing the entire battery is
simpler and cheaper.
Before storing the battery, it should be properly charged, the vent plugs put tightly in place, and the
leads disconnected to prevent use during idle periods. The battery should be charged at intervals
during the idle period. Before returning the battery to service, it should be thoroughly charged. The
battery will be sufficiently charged when, after a 3-hour period, the specific gravity does not rise any
higher with the electrolyte gassing and a charging rate of 1-1/2 amperes.
Long battery life and trouble-free service is obtained from the battery if the following simple tips are
observed:
(1) Keep it clean.
(2) Keep it charged.
(3) Maintain proper electrolyte levels.
(4) Keep specific gravity equal among all cells.
J. Preparing New Dry-Charged Battery for Installation
CAUTION: PRIOR TO INSTALLING A NEW DRY-CHARGED BATTERY, FOLLOW THE
PREPARATION INSTALLATION INSTRUCTIONS FURNISHED WITH THE BATTERY
BY TELEDYNE.
The Teledyne, dry-charged, Model GILL/G-243 Battery shall be stored as received from Teledyne.
Do not remove vent seals, add acid, nor attempt to charge a dry-charged battery until the time
arrives to install the battery into an airplane.
9. Battery (Valve-Regulated Lead-Acid - Gill Model G-250S) ( S/N’s 4636375 and up )
Gill valve-regulated lead-acid (VRLA) non-maintainable batteries are fully charged when they leave the
factory. Service includes the entire battery system consisting of the battery and battery compartment.
These services shall be completed every 50 operating hours or 30 days, whichever occurs first, and at
every 100 hour inspection.
A. Troubleshooting
See Chart 2.
B. Removal
(1) Remove battery access plate from floor of forward baggage compartment.
CAUTION: REMOVE NEGATIVE CABLE FIRST, BEFORE EXPOSING AND LOOSENING
POSITIVE TERMINAL WING NUT, TO AVOID SHORT CIRCUITS AND
ELECTRICAL BURNS.
(2) Pull back rubber battery terminal boots, loosen wing nuts and disconnect battery cables.
(3) Remove vent hose at battery manifold.
(4) Remove battery hold down bolts. Lift battery manifold cover off battery and place cover away
from carpeting etc, due to acid contamination on inside surface.
(5) Lift battery out of compartment.
(6) Remove the vent hose that connects through the firewall.
