An authorized operator should inspect the engine battery
monthly. At this time, the battery fluid level should be
checked using a load tester and distilled water added if
needed. Battery cables and connections should also be
inspected for cleanliness and corrosion.
Once every six months, an IASD should inspect the
battery system. At this time, the battery condition and
state of charge should be checked using a load test
battery. The battery should be recharged or replaced as
required.
Battery service is to be performed or supervised by
personnel knowledgeable of batteries and the required
precautions. Keep unauthorized personnel away.
Observe the following precautions when working on
batteries:
• Remove watches, rings, or other metal objects.
• Use tools with insulated handles.
• Wear rubber gloves and boots.
• Do not lay tools or metal parts on top of battery.
•
Disconnect charging source prior to connecting or
disconnecting battery terminals.
NOTE: Spilled electrolyte is to be washed down with an
acid neutralizing agent. A common practice is to use a
solution of one pound (500 grams) bicarbonate of soda
(baking soda) to one gallon (four liters) of water. The
bicarbonate of soda solution is to be added until the evi-
dence of reaction (foaming) has ceased. The resulting
liquid is to be flushed with water.
• Discharge static electricity before touching battery
by first touching a grounded metal surface.
