C. Check for signs of wetness or leakage on the top
of the battery which might indicate a loose or mis-
sing filler cap, overcharging, loose terminal post or
overfilling. Also, check the battery case for dirt and
oil. Clean the battery with a solution of baking soda
and water, then rinse it with clean water.
D. Check that the cover seal is not broken away.
Replace the battery if the seal is broken or leaking.
E. Check the electrolyte level in each cell. If the lev-
el is below the tops of the plates in any cell, fill all
cells with distilled water to the bottom of the cap
tubes. Charge at 15 to 25 amps for 15 minutes to al-
low sufficient mixing of the electrolyte.
