What Causes Charge Imbalance in a Lead Acid Battery? Charge imbalance in a lead-acid battery occurs due to various factors that disrupt the equal distribution of charge among the cells. The main causes of charge imbalance in a lead-acid battery include: 1. Overcharging 2. Undercharging 3. Cell aging 4. Temperature variations 5. Poor maintenance 6.

The stepwise procedure for an equalizing charge is as follows: i. Charge the battery by using constant current-constant voltage (CC-CV) till a voltage of 2.4 VPC. ii. In order to ensure each cell is equalized to full charge, i.e., 100 %SOC, a voltage setting of 2.7 VPC is needed for flooded lead-acid battery cells.
Consequently, when conventional lead–acid batteries are used in such configura- tions, the continuous cycling encountered in normal driving will almost certainly lead to divergence in the states- of-charge of the unit cells and thereby demand periodic equalization charges.
In the realm of battery maintenance, equalizing charge is a crucial procedure, particularly for flooded lead-acid batteries. This specific maintenance technique ensures optimal performance and extends the lifespan of batteries by addressing common issues such as sulfation and voltage imbalances.
