KEY POINTS[ edit ]
Lead-acid batteries, also known as lead storage batteries, can store a lot of charge and provide high current for short periods of time.
The basic design of lead-acid batteries has not changed significantly since 1859 when Planté designed them, although some improvements were made by Faure.
Lead-acid batteries are capable of being recharged, which is important for their use in cars.
Discharging the stored energy relies on both the positive and negative plates becoming lead(II) sulfate and the electrolyte losing much of its dissolved sulfuric acid.
