Batteries
Warning
Do not smoke or allow any flames or
sparks in the vicinity while checking
or filling the battery. The battery
generates
hydrogen,
a
highly
explosive gas.
Warning
Battery acid (electrolyte) is extremely
dangerous.
Serious
injury
to
personnel may result if battery acid
contacts skin or eyes.
Inspect the batteries for corrosion, cracks, leaks,
or damaged vent caps. Check for loose battery cables
by hand. Remove vent caps and ensure that the
electrolyte level is about X in. above the plates (figs.
47 and 48). Refer to TM 9-6140-200-14.
