What are lead-acid batteries? Lead-acid batteries are used in motorized vehicles, for storage of energy generated by photovoltaic cells and wind turbines, and for back-up power supplies.
If the battery was filled and now there''s electrolyte on the floor, the real problem is someone filled the battery when it was discharged. When the battery discharges the fluid level drops, if you add water it will overflow. That will decrease its life significantly because now there''s a lower concentration of acid in the battery.

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 of

This comes to 167 watt-hours per kilogram of reactants, but in practice, a lead–acid cell gives only 30–40 watt-hours per kilogram of battery, due to the mass of the water and other constituent parts. In the fully-charged state, the negative plate consists of lead, and the positive plate is lead dioxide.
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.
