A lead-acid battery is a type of rechargeable battery that uses a combination of lead plates and sulfuric
acid to produce electrical energy. It is the oldest type of rechargeable battery and is commonly used in
automobiles, boats, motorcycles, and other vehicles. Lead-acid batteries were first developed in 1859 by
French physicist Gaston Planté and are still the most widely used type of battery today.
Lead-acid batteries are built up of several cells that are connected in series and parallel depending on the
voltage and capacity needed. Each cell consists of two electrodes (positive and negative) and electrolyte,
which is a mixture of sulfuric acid and water. When the battery is discharged, the lead plates in each cell
react with the sulfuric acid to form lead sulphate, releasing electrons and generating electrical current.
When the battery is recharged, the lead sulphate reverses back into lead and sulfuric acid, and the
electrons are absorbed by the plates.
Lead-acid batteries are relatively inexpensive and have relatively good energy density and cycle life. Lead
acid batteries can be recharged many times, and they’re also capable of providing high current discharges,
which makes them ideal for applications like starting automobile engines. However, lead-acid batteries are
also relatively heavy and have a low voltage output, which makes them unsuitable for many applications.
Overall, lead-acid batteries are a reliable and cost-effective option for many applications. They offer good
energy density and cycle life and can be easily recharged. However, Lead acid batteries are also relatively
heavy and have a low voltage output, which limits their use in some applications.
