The factor limiting the charging speed of lead–acid batteries is often the dissolution of the sulphate crystals in the negative active mass. This greater resistance means that the cell reaches the constant-voltage stage at a lower state of charge. As such, the cell needs longer in the constant-voltage stage to reach a full state of charge.
Periodically fully charging a lead–acid battery is essential to maintain capacity and usability. In traditional UPS or cyclic use, full recharge normally occurs following any discharge. This is in contrast to partial-state-of-charge use. In this use case, multiple shallow cycles of less than 50% of the battery capacity occur before a full charge.
The Eq. (5) is used to describe the B (x) life of lead-acid batteries, where p is the failure probability and γ is the respective hazard rate . (5) B x p = γ + θ − ln 1 − p 1 / β The B (1) life of the lead-acid battery is calculated as 1157 cycles.
The effect of fast charging on the cycle life of lead-acid batteries used for e-rickshaw is demonstrated. The average coulombic efficiency of 93 %, maximum top of charge voltage of 2.6 V, and temperature rise of 5-6 oC. The predicted life of lead-acid batteries subjected to fast charging coupled with periodic equalizing charge is 1296 cycles.
Abstract. The traditional methods of charging lead-acid batteries depend on stabilizing the current or voltage through simple electronic circuits, which causes the shorten the life of the batteries due to damage to the electrodes or the hot and dry batteries.
An approach to increase the life span of standby lead–acid batteries is to reduce the deterioration of the positive grid. The use of a low potential on a positive electrode allows it to be within the minimum zone of corrosion (Armstrong et al. 2008; Bhatt et al. Oct. 2005).

The Ultimate Guide To Optimal Charging Current For A New Lead Acid Battery
If you use a lower charging current than recommended, the charging time will be longer. However, it will not cause any harm to the battery. It is better to charge a lead acid battery at a slower rate rather than risk damaging it with a higher current. Why is it important to follow the recommended charging current for a new lead acid battery?
