Step 1.
VISUAL INSPECTION
Check for obvious damage such as cracked or
broken case that shows loss of electrolyte,thermal
damage,etc.
Obvious damage No obvious damage
Replace battery
Electrolyte level is below top of
plates in one or more cells
Add water up to just above separators.
Charge for 15min.with 15.25 amp
Check electrolyte level
Electrolyte level is above top of
plates in all cells
-proceed to step 2
Step 2
Hydrometer test
50 points or more variation
between highest and lowest cell
Less than 50 points variation
between highest and lowest cell
Specific gravity 1.225 or above
Proceed to step 3
Recharge battery and if 50 points
variation persists,replace battery
Specific gravity:Below 1.225
Charge until all cells are at least
1.225
Turn on head lamps (or 15-A
load)for 15seconds
Proceed to step 3
