Therefore it is noteworthy to study the important characteristics of this battery. Terminal Voltage - When the battery delivers current, the voltage terminal voltage is less than its EMF due to its internal resistance. Lead acid cell has less lead sulphate that will clogged the pores of the battery once there is continous flow of current.
Reactions of Sealed Lead Acid Batteries When the lead acid battery is discharging, the active materials of both the positive and negative plates are reacted with sulfuric acid to form lead sulfate.
When the lead acid battery is discharging, the active materials of both the positive and negative plates are reacted with sulfuric acid to form lead sulfate. After discharge, the concentration of sulfuric acid in the electrolyte is decreased, and results in the increase of the internal resistance of the battery.
The charging voltage for the valve regulated lead acid battery should not be in excess of the gassing voltage, which is 2.4~2.5V/cell. The gassing voltage varies with temperature, and is decreased as the temperature is increased. Its temperature coefficient is –5.0mV/°C/cell.
Lead–acid batteries were used to supply the filament (heater) voltage, with 2 V common in early vacuum tube (valve) radio receivers. Portable batteries for miners' cap headlamps typically have two or three cells. Lead–acid batteries designed for starting automotive engines are not designed for deep discharge.
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.
