Lead–acid batteries, invented in 1859 by French physicist Gaston Planté, are the oldest type of rechargeable battery. Despite having a very low energy-to-weight ratio and a low energy-to-volume ratio, their ability to supply high surge currents means that the cells maintain a relatively large power-to-weight ratio. These features, along with their low cost, make them attractive for use in motor vehicles to provide the high current required by automobile starter motors.

As they are very inexpensive compared to newer technologies, lead-acid batteries are widely used even when surge is not important and other designs with higher energy densities. Large-format lead-acid designs are widely used for storage in backup power supplies in cell phone towers, high-availability settings like hospitals, and stand-alone power systems. For these roles, modified versions of the standard cell may be used to improve storage times and reduce maintenance requirements, gel-cells and absorbed glass-mat batteries are common in these roles.

Lead-acid batteries sales accounts for 40-45% of the value from batteries sold worldwide (1999, not including China and Russia), a manufacturing market value of about US$15 billion.[1]

History

Main article: History of the battery

In 1859, Gaston Planté's lead-acid battery was the first battery that could be recharged by passing a reverse current through it. Planté's first model consisted of two lead sheets separated by rubber strips and rolled into a spiral.[2] His batteries were first used to power the lights in train carriages while stopped at a station. In 1881, Camille Alphonse Faure invented an improved version that consisted of a lead grid lattice into which a lead oxide paste was pressed, forming a plate. This design was easier to mass-produce.

In the 1970s the valve-regulated lead acid battery (often called "sealed") was developed; it used a gel electrolyte instead of a liquid, allowing the battery to be used in different positions without leakage.
