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.

The active material is usually made into a paste by adding sulfuric acid and water. The paste acts like a sponge soaking up the electrolyte that is added later and keeping this electrolyte close to the plates to improve the battery''s performance. Figure 1: each cell is connected to the next in series. The plates are then assembled in alternating order – positive,
The more common method these days to describe the internal resistance of a lead-acid battery is the AC imped-ance measurement. The battery will not be discharged under load like in the DC resistance measurement method, but a small AC current is imposed on the battery and the response signal for amplitude and voltage phase shift is measured.

When a cell discharges, the lead and diluted acid undergo a chemical reaction that produces lead sulfate and water. When a cell is subsequently charged, the lead sulfate and water are turned back into lead and acid. In all lead–acid battery designs, charging current must be adjusted to match the ability of the battery to absorb the energy.
Lead-Acid Battery Construction. The lead-acid battery is the most commonly used type of storage battery and is well-known for its application in automobiles.

The Internal resistance of the battery in this instance is A: .52 ohm. B: 2.52 ohms. C: 5 ohms., 8086: If electrolyte from a lead-acid battery is spilled in the battery
AGM batteries use a fiberglass mat to hold the electrolyte in place, making them more resistant to vibration and shock. Gel batteries use a gel-like electrolyte that is less prone to leakage and can be used in any orientation. Both AGM and Gel batteries are popular in applications that require reliable backup power, such as telecommunications, UPS systems,
Lead and sulphuric acid are extremely hazardous and pollute soil, water as well as air. Irrespective of the environmental challenges it poses, lead-acid batteries have remained an important source of energy. Designing green and sustainable battery systems as alternatives to conventional means remains relevant.
Lead acid batteries typically have coloumbic efficiencies of 85% and energy efficiencies in the order of 70%. Depending on which one of the above problems is of most concern for a
Lead–acid cells consist of two plates of lead, which serve as electrodes, suspended in an electrolyte consisting of diluted sulfuric acid. VRLA cells have the same chemistry, except the electrolyte is immobilized. In AGM this is accomplished with a fiberglass mat; in gel batteries or "gel cells", the electrolyte is in the form of a paste like gel created by adding silica and other gelling age

The lead-acid battery represents the oldest rechargeable battery technology. Lead acid batteries can be found in a wide variety of applications including small-scale power storage such as UPS systems, ignition power sources for automobiles, along with large, grid-scale power systems. The spongy lead act as the anode and lead dioxide as the cathode.
The production and escape of hydrogen and oxygen gas from a battery causes water loss and water must be regularly replaced in lead acid batteries. Other components of a battery system do not require maintenance as regularly, so water loss can be a significant problem. If the system is in a remote location, checking water loss can add to costs.
The battery may also fail as an open circuit (that is, there may be a gradual increase in the internal series resistance), and any batteries connected in series with this battery will also be affected. Freezing the battery, depending on the type of lead acid battery used, may also cause irreversible failure of the battery.
