BATTERY SPECIFIC GRAVITY - CHECK
Battery testing includes two basic procedures.
1.
Visual Inspection
2. State of charge (a. Specific gravity & b. Open circuit voltage)
Visual Inspection -
Battery service should begin with thorough visual inspection. This inspection may
reveal simple and easily correctable problems.
1.
Check for cracks in the battery case and broken terminals which allows electrolyte leakage.
Replace the battery if necessary.
2.
Check for corrosion on terminals and dirt/acid on the battery case top. Clean the terminals
and the battery case top with mixture of water and baking soda. A battery wire brush tool
can also be used to clear heavy corrosion on the terminals.
3.
Check for a loose battery hold down and tighten it if necessary.
4.
Check the electrolyte level by viewing through the translucent plastic case or removing the
vent caps and looking directly into the battery. Top up required amount of distilled water.
5.
Check for cloudy or discolored electrolyte caused by overcharging or vibration of the battery.
This will cause high self discharge. Correct the cause or replace the battery if necessary.
