Battery Post Repair

TM 9-6140-200-14

b. Battery Post Repair (2HN, 4HN and 6TN Only).

WARNING

The melting, sawing and use of pig lead must be performed

in accordance with local SOP complying with OSHA

requirements.

Fumes from molten lead and dust size lead particles can be

injurious to health if ingested (taken into the body by month or

through breathing). Use protective clothing and equipment to

prevent injury to personnel.

To protect personnel from lead and acid fumes, batteries must

be placed on work bench having an overhead exhaust in

operation before repairing battery posts.

To avoid danger of explosion, steps (1) through (4) below

must be followed carefully. Pay special attention to step (2)

below. A low battery electrolyte level creates a potential

for hydrogen gas to be trapped in the battery and when

subjected to open flumes, sparks or other ignition sources

can explode and cause injury to personnel and cause

equipment damage.

(1) Remove all filler caps from battery.

(2) Make sure electrolyte level is up to ledge in filler opening. Add distilled

water as necessary.

NOTE

Do not add electrolyte at this time.

(3) Let battery stand for 5 minutes to permit explosive hydrogen gas to escape

and dissipate.
