Lead-Acid Battery Specific Gravity. When a lead-acid battery is in a nearly discharged condition, the electrolyte is in its weakest state. Conversely, the electrolyte is at its strongest (or greatest density) when the battery is fully charged. The density of electrolyte related to the density of water is termed its specific gravity.

Lead–acid batteries are comprised of a lead-dioxide cathode, a sponge metallic lead anode, and a sulfuric acid solution electrolyte. The widespread applications of lead–acid batteries include, among others, the traction, starting, lighting, and ignition in vehicles, called SLI batteries and stationary batteries for uninterruptable power supplies and PV systems.
Figure 4: Comparison of lead acid and Li-ion as starter battery. Lead acid maintains a strong lead in starter battery. Credit goes to good cold temperature performance, low cost, good safety record and ease of recycling. [1] Lead is toxic and environmentalists would like to replace the lead acid battery with an alternative chemistry.
How Does a Lead-Acid Battery Work? To put it simply, the battery''s electrical charge is generated when the sulphate in the sulphuric acid becomes bonded to the lead. The electrical charge is replenished by reversing this reaction. That is, the sulphate goes back into the sulphuric acid and, thus, the battery is recharged. ...
Car battery acid is an electrolyte solution that is typically made up of 30-50% sulfuric acid and water.

Each cell produces 2 V, so six cells are connected in series to produce a 12-V car battery. Lead acid batteries are heavy and contain a caustic liquid electrolyte, but are often still the battery of choice because of their high current density. The lead acid battery in your automobile consists of six cells connected in series to give 12 V.
A lithium-ion battery, for instance, often has a larger capacity than a lead-acid or nickel-metal hydride battery of the same size. Temperature : A battery''s capacity is temperature-dependent. Higher temperatures often cause rapid aging at the price of momentary capacity increases.
