The lead-acid battery is a type of rechargeable battery first invented in 1859 by French physicist Gaston Planté. It is the first type of rechargeable battery ever created. Compared to modern rechargeable batteries, lead-acid batteries have relatively low energy density. Despite this, they are able to supply high surge currents.

Every part of each UltraBattery – lead, plastic, steel and acid – is virtually 100% recyclable for later reuse. 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.
Even if a cell is brought to a fully discharged state without reversal, however, damage may occur over time simply due to remaining in the discharged state. An example of this is the sulfation that occurs in lead-acid batteries that are left sitting on a shelf for long periods. For this reason it is often recommended to charge a battery that is ...
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 ...
Lead–acid batteries did not achieve the safety and portability of the dry cell until the development of the gel battery. A common dry cell is the zinc–carbon battery , sometimes called the dry Leclanché cell , with a nominal voltage of 1.5 volts , the same as the alkaline battery (since both use the same zinc – manganese dioxide ...
Conventional lead–acid batteries consist of a number of plates of lead and lead dioxide suspended in a cell filled with weak sulfuric acid. Lead oxide reacts with the sulfur and oxygen in the acid to give up an electron, leaving the plate positively charged and producing lead sulfate. Lead reacts with the acid by taking in two electrons ...
A deep-cycle battery powering a traffic signal. A deep-cycle battery is a battery designed to be regularly deeply discharged using most of its capacity. The term is traditionally mainly used for lead–acid batteries in the same form factor as automotive batteries; and contrasted with starter or cranking automotive batteries designed to deliver only a small part of their capacity in a short ...
