A lead-acid battery cell is fully charged with a specific gravity of 1.265 at 80° F. For temperature adjustments, get a specific gravity reading and adjust to temperature by adding .004 for every 10° F above 80° F and subtracting .004 for every 10° F below 80° F.
For temperature adjustments, get a specific gravity reading and adjust to temperature by adding .004 for every 10° F above 80° F and subtracting .004 for every 10° F below 80° F. A fully charged lead acid battery used in todays car has a specific gravity of 1.265 fully charged. Use this handy guide to perform this test using a battery hydrometer.
The lead-acid battery used in today's automobile is made of plates, lead, and lead oxide in an electrolyte solution. This solution consists of 65% water and 35% sulfuric acid. This solution's specific gravity or weight increases as the battery charges and decreases as the battery discharges.
A typical lead–acid battery contains a mixture with varying concentrations of water and acid. Sulfuric acid has a higher density than water, which causes the acid formed at the plates during charging to flow downward and collect at the bottom of the battery.
However, it has been demonstrated that battery acid when the battery is fully charged has the maximum density at 800F or 26.670C as the temperatures drop below 800F, the battery will contract increasing the specific gravity of the acid. As temperatures raise above 80 0 F, the battery acid expands lowering the specific gravity of the acid.
According to a 2003 report entitled "Getting the Lead Out", by Environmental Defense and the Ecology Center of Ann Arbor, Michigan, the batteries of vehicles on the road contained an estimated 2,600,000 metric tons (2,600,000 long tons; 2,900,000 short tons) of lead. Some lead compounds are extremely toxic.

The lead–acid cell can be demonstrated using sheet lead plates for the two electrodes. However, such a construction produces only around one ampere for roughly postcard-sized plates, and for only a few minutes. Gaston Planté found a way to provide a much larger effective surface area. In Planté''s design, the positive and negative plates were formed of two spirals o…
