The theoretical charging of a lead acid battery operates in three phases

graph of lead battery operation



- Phase 1: the current is limited to a rate of about 1/5 of the rated capacity. The voltage increases gradually until it reaches its maximum regulated threshold to 2.35 V / element.

- Phase 2 : the charging voltage is regulated to 2.35 V / element, the charging current then decreases to less than C/100. This phase should last up to 20 hours, the voltage must not stay above 2.26 V longer. The battery is chargedat the end of this phase

- Phase 3: once the battery is charged (after about 20 hours of charging) it switches to trickle charge (Floating) to keep it at 100% load. Then the voltage applied to the battery is around 2.26 V / element.
