WARNING

Do not smoke or allow flame or sparks in the vicinity while servicing, removing, or installing

batteries. Never disconnect any charging unit circuit or battery circuit cable from battery when the

charging unit is operating. Batteries generate hydrogen, a highly explosive gas. Severe personal

injury could result.

To avoid sparks when removing battery cables, always begin by removing negative battery cable

first.

Batteries are filled with acid electrolyte solution. Always wear protective clothing, rubber gloves,

and eye protection when servicing, removing or installing batteries.

Always check electrolyte level with engine stopped. Do not smoke when checking the battery. Do

not use an exposed flame to check battery levels. Protect eyes when checking battery level.

Do not overfill batteries so that water splashes acid from cell openings. Battery acid can cause skin

irritations or burns.

NOTE

Battery voltage test can be performed on engine. If the on-engine test shows a defect, remove batteries

for further testing. Refer to STE/ICE battery voltage test. For additional testing requirements refer to

TM 9-6140-200-14.
