Charging of a lead acid battery can be done in various ways: Constant voltage charging is most commonly used for a sealed lead acid battery. The initial charging current in a constant voltage battery charger is limited by a resistor. Figure 1 below shows the charging over time for a constant voltage charger. Figure 1 Credit BB Battery
In the multi stage charging of a lead acid battery, the charger goes into a bulk charging state where the current and voltage are at a higher rate to get a majority of the battery charged. The next stage of the charging process is also known as absorption charge.
In this method the charging current is high in the beginning when a battery is in discharged condition, and it gradually drops off as the battery picks up charge resulting in increased back emf. Charging at constant voltage may be carried out only when the batteries have the same voltage, for example, 6 or 12 or 24 V.
For charging the valve-regulated lead-acid battery, a well-matched charger should be used because the capacity or life of the battery is influenced by ambient temperature, charge voltage and other parameters. Cycle use is to use the battery by repeated charging and discharging in turn.
(a) Constant Voltage Charging: In this method, the charging voltage is kept constant throughout the charging process. In this method the charging current is high in the beginning when a battery is in discharged condition, and it gradually drops off as the battery picks up charge resulting in increased back emf.
