(d) Inspect the battery box for corrosion and spilled electrolyte. If the battery box, battery
cables, or battery terminals need to be cleaned, use a solution of bicarbonate of soda and
clean fresh water. Do not allow bicarbonate of soda to enter the battery cells.
CAUTION: When cleaning a battery, never allow bicarbonate of soda to enter the bat-
tery cells or permanent battery damage will result.
(e) Rinse the battery with clean fresh water and wipe clean with a dry cloth.
(f) Check battery vent for any obstructions.
(g) Install the battery. (Refer to 24-30)
(2) Removal - Battery 1
WARNING:
All electrical circuits must be off, prior to disconnecting battery cables.
Always remove the negative battery cable first, then remove the positive
cable and insulate both cable ends to prevent accidental reconnection. After
insulating cable ends and battery terminals, disconnect the battery vent
tube. Always wear a face shield and remove all jewelry before servicing the
battery. Metal objects may fuse to electrical connections and cause severe
burns.
Because acid does not evaporate, acid should never be added unless the
electrolyte has been lost by spillage. When it is necessary to add acid, the
battery should be fully charged, on charge, and gassing freely. Specific
gravity then may be adjusted by adding acid or distilled water, or drawing
off electrolyte.
Note: The battery should be removed from the airplane prior to inspection. The battery
box should be washed out thoroughly and dried each time the battery is removed.
The battery vent hose should be inspected periodically for obstructions. If adding
distilled water in freezing weather, charge battery long enough to mix electrolyte
and water. Use a bristle brush to clean the battery.
(a) Verify Start/Ignition Key Switch is in “OFF” position and remove key. (Refer to POH)
(b) Ensure BAT 1, BAT 2, and AVIONICS master switches are in the off position.
(c) Pull BAT 2 circuit breaker to the off position.
(d) Remove the upper engine cowling. (Refer to 71-10).
CAUTION: After battery disconnection, insulate battery terminals to prevent accidental
connection.
(e) Remove the negative battery cable first and then the positive battery cable.
(f) Insulate battery terminals. (Refer to 24-30)
(g) Remove the battery vent hose.
(h) Remove cotter pins from the hold-down bolts.
(i) Remove the battery hold-down bracket, and remove the battery from the airplane.
