MALFUNCTION
TEST OR INSPECTION
CORRECTIVE ACTION
THE BATTERY FAILS TO CHARGE (Continued)
(1)
Remove the cell caps and check the electrolyte level. Add distilled water it the level is below the
top of the plates.
(2)
Check the specific gravity.
(3)
If the specific gravity is between 1.250 and 1.280, the cells are ok. Go to Step 2.
(4)
If the specific gravity is between 1.225 and 1.250, the cells are still in fair condition. Go to Step
2.
(5)
If the specific gravity is below 1.150 in any one cell, replace the battery and go to Step 2 if the
new battery fails to charge.
(6)
If the specific gravity in one cell is 0.050 more or less than the other cells, and charging does not
bring the charge to a 50% charge, replace the battery and go to Step 2 if the new battery fails to
charge.
