Comparison of Voltage Charging Techniques to Increase the Life of Lead Acid Batteries

Batteries are an integral part of stationary applications either as primary source or back-up. Lead acid batteries are predominantly used for this. The main function of secondary batteries is charging and discharging. Sulphation is the main problem of lead acid batteries. The voltage charging techniques are proving to be effective for reduction of sulphation and increasing the life of lead acid batteries. This paper compares the two types of voltage charging: constant voltage and pulse voltage. The pulse voltage charging is shown to charge faster and reduce sulpahtion in lead acid batteries.
