Battery Acid Specific Gravity
Density is a measure of mass per unit volume. While on the other hand, specific gravity is a measure of the relative density of a fluid with respect to another liquid. Density being a ration between weight and volume is measures in gm/ cm 3 (grams per cubic centimeter), Kg/ m 3 (kilogram per cubic meter), lb./ft 3 (pound per cubic feet)

How Does Lead-Acid Batteries Work?
Lead-acid batteries are prone to a phenomenon called sulfation, which occurs when the lead plates in the battery react with the sulfuric acid electrolyte to form lead sulfate (PbSO4). Over time, these lead sulfate crystals can build up on the plates, reducing the battery''s capacity and eventually rendering it unusable.
