Internal view of a small lead–acid battery from an electric-start–equipped motorcycle. 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.
A 12V VRLA battery, typically used in small uninterruptible power supplies and emergency lamps.. A valve regulated lead‐acid (VRLA) battery, commonly known as a sealed lead-acid (SLA) battery, [1] is a type of lead-acid battery characterized by a limited amount of electrolyte ("starved" electrolyte) absorbed in a plate separator or formed into a gel, proportioning of the negative and ...
A typical 12 V, 40 Ah lead-acid car battery. An automotive battery, or car battery, is a rechargeable battery that is used to start a motor vehicle.. Its main purpose is to provide an electric current to the electric-powered starting motor, which in turn starts the chemically-powered internal combustion engine that actually propels the vehicle.
Lead–acid batteries powered such early modern EVs as the original 1996 versions of the EV1. There are two main types of lead–acid batteries: automobile engine starter batteries, and deep-cycle batteries which provide continuous electricity to run electric vehicles like forklifts or golf carts.

The lead–acid battery, invented in 1859 by French physicist Gaston Planté, is the oldest type of rechargeable battery. Despite having a very low energy-to-weight ratio and a low energy-to-volume ratio, its ability to supply high surge currents means that the cells have a relatively large power-to-weight ratio .
Large-scale recycling facilities for these batteries are already available and 96% of lead acid batteries used in the US are recycled. [19] Battery manufacturers recover and separate the lead, plastics and acid from VRLA batteries. The lead is smelted and refined for reuse. Plastic parts are cleaned, ground, extruded and moulded into new ...

For instance, a typical 12 V lead–acid battery has six galvanic cells connected in series, with the anodes composed of lead and cathodes composed of lead dioxide, both immersed in sulfuric acid. Large central office battery rooms – in a telephone exchange to provide power for subscribers' land-line telephones, for instance – may have many ...
