CHECKING ELECTROLYTE SPECIFIC
GRAVITY
CAUTION: Battery gas can explode. Keep
sparks and flames away from batteries. Use a
flashlight to check battery electrolyte level.
Never check battery charge by placing a metal
object across the posts. Use a voltmeter or
hydrometer.
Always remove grounded (-) battery clamp first
and replace it last.
Sulfuric acid in battery electrolyte is poisonous.
It is strong enough to burn skin, eat holes in
clothing, and cause blindness if splashed into
eyes.
Avoid the hazard by:
1. Filling batteries in a well-ventilated area.
2. Wearing eye protection and rubber gloves.
3. Avoiding breathing fumes when electrolyte is
added.
4. Avoiding spilling or dripping electrolyte.
5. Use proper jump start procedure.
If you spill acid on yourself:
1. Flush your skin with water.
2. Apply baking soda or lime to help neutralize
the acid.
3. Flush your eyes with water for 15--30
minutes. Get medical attention immediately.
If acid is swallowed:
1. Do not induce vomiting.
2. Drink large amounts of water or milk, but do
not exceed 1.9 L (2 quarts).
3. Get medical attention immediately.
Check the specific gravity of electrolyte in each battery
cell.
