Disassembled Battery

A. Visually check each cell carefully for evidence of electrolyte leakage, cracks,
corrosion, burns, holes, or cross threaded terminals. Excessive salt around a terminal
post indicates leakage. Refer to REPAIR for replacement of lower terminal o-ring if
leakage is evident.
B. Visually check each cell vent valve assembly (3) for defective o-rings, cracks, or other
physical damage. Replace defective o-rings (4). Vent valves that visually appear
damaged should be tested in accordance with the procedures in TESTING and
FAULT ISOLATION and/or discarded if necessary.
C. Inspect intercell terminal links (11-15) for bends, tarnish, loss of nickel plating,
corrosion or burns. Tarnish can be polished off with a fine wire brush. Replace any
defective intercell links.
D. Spacers (27) should be clean and free of cracks or holes. Replace any that are
defective.
CAUTION: A DEFECTIVE BATTERY CONNECTOR RECEPTACLE CAN
E. Check the battery connector receptacle (16) for evidence of arcing, corrosion, cracks
or cross threaded terminals. Using the same methods described in the cell to case
testing, test the battery connector receptacle by measuring the resistance between the
positive pin and the connector shell, and the negative pin and the connector shell.
Replace with factory new if found to be defective (DISASSEMBLY, ASSEMBLY).
