A lead acid battery is a type of battery that uses electrodes of lead oxide and metallic lead, which are separated by an electrolyte of sulphuric acid. Its energy density ranges from 40-60 Wh/kg. In an Absorbent Glass Mat (AGM) Lead Acid Battery, the separators between the plates are replaced by a glass fibre mat soaked in electrolyte.
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.
The term “battery acid” refers to the electrolyte used in batteries. For lead acid batteries this is sulfuric acid (H 2 SO 4). Sulfuric acid is colorless, odorless, and strongly acidic. Why measure the density / specific gravity of battery acid? Knowing the specific gravity of the electrolyte in batteries gives insight into the level of charge.
Lead Acid batteries have an energy density of approximately 40-60 Wh/kg. AGM (absorbent glass mat) Battery – the separators between the plates are replaced by a glass fibre mat soaked in electrolyte. Cold cranking amps (CCA) is the rating that measures a battery’s cranking power.
A deep-cycle lead acid battery should be able to maintain a cycle life of more than 1,000 even at DOD over 50%. Figure: Relationship between battery capacity, depth of discharge and cycle life for a shallow-cycle battery. In addition to the DOD, the charging regime also plays an important part in determining battery lifetime.
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 particular application, appropriate modifications to the basic battery configuration improve battery performance.
