A lead-acid battery is a type of rechargeable battery used in many common applications such as starting an automobile engine. It is called a “lead-acid” battery because the two primary components that allow the battery to charge and discharge electrical current are lead and acid (in most case, sulfuric acid). Lead.

Customer ServiceThe lithium-ion batteries in our mobile phones have a pretty good self-discharge rate of around 2–3 per cent per month, and our lead-acid car batteries are also pretty reasonable—they tend to lose 4–6 per cent per month. Nickel-based batteries lose around 10–15 per cent of their charge per month, which is not very good if you plan to
Customer ServiceIn 1859 a French physicist, Gaston Planté, discovered that pairs of lead oxide and lead metal electrodes, when immersed in a sulfuric acid electrolyte, generated electrical energy and could subsequently be recharged. A series of further technical improvements by other investigators led to commercial production of lead-acid storage batteries by 1889.

It is important to note that lead-acid batteries do not produce an electrical charge. They are only capable of receiving a charge from another source and discharging it later. The battery uses chemical reactions between the lead and acid to both store and discharge electrical current. Batteries are divided into cells.
