Free QuoteThis concentration of sulfuric acid is characteristic of a nearly fully charged battery. For partially or fully discharged battery, the sulfuric acid concentration and sulfuric acid–specific gravity are lower. Lead–acid batteries are characterized by a direct dependence of battery open-circuit voltage on the state of charge.
The limitation voltage for most lead–acid batteries is around 2.4 V. The next stage (after the limitation voltage is reached) is to continue charge at the limitation voltage value (also called set voltage).
One of the most important properties of lead–acid batteries is the capacity or the amount of energy stored in a battery (Ah). This is an important property for batteries used in stationary applications, for example, in photovoltaic systems as well as for automotive applications as the main power supply.
A lead–acid battery cannot remain at the peak voltage for more than 48 h or it will sustain damage. The voltage must be lowered to typically between 2.25 and 2.27 V. A common way to keep lead–acid battery charged is to apply a so-called float charge to 2.15 V.
A typical lead–acid battery contains a mixture with varying concentrations of water and acid. Sulfuric acid has a higher density than water, which causes the acid formed at the plates during charging to flow downward and collect at the bottom of the battery.
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.
