Electrolyte level -- In hot climates, check electrolyte level daily.
Specific gravity -- Batteries should have a weaker electrolyte in hot areas (1.200 to 1.225 at full charge). Have
specific gravity level checked by unit maintenance.
Self--discharge -- A battery will self--discharge faster if left standing for long periods in high temperatures. If
the vehicle is parked for several days, have the batteries removed by unit maintenance and stored in a cool
2. Hull and Crew Compartment.
In hot, damp areas, corrosion will occur on all parts of the materiel. It will appear as rust and paint blisters on
metal surfaces and mildew, mold, or fungus growth on fabric and glass. Protect all unfinished, exposed metal
surfaces with a film of preservative lubricating oil. Cables and terminals should be protected by silicone
Frequently inspect inactive vehicles. Remove corrosion from exterior with abrasive
paper or cloth and apply a protective coating of paint, oil or suitable rust preventative.
Inspect parts often for moisture or corrosion. Thoroughly dry all exposed, unpainted surfaces such as machine
gun bore, breech and firing mechanisms, and oil as prescribed in TM 9--1005--213--10. In dry, dusty, or sandy
areas, leave exposed surfaces, such as recoil slides, free of oil or preservative. Combining the oil with sand
makes an abrasive paste far more damaging than no oil at all. At other times keep these surfaces lubricated to
4. Vision Devices.
Inspect parts for moisture, corrosion, or fungus growth. In dry, dusty or sandy areas, keep exposed optical
surfaces protected from blowing sand and dirt.
