Lead-Acid Battery (LAB) is a secondary type battery that can work on static and dynamic electrolyte treatments. Dynamic batteries are a popular type of wet batteries recently due to high capacity storage, long life cycles, and simple designs. Dynamic Lead-Acid batteries have been chosen for this study to explore the characteristics of a lead-acid battery system consisting of 3 cells, 30% H2SO4 and a peristaltic pump. Twenty cycles of charge-discharge tests were carried out with a constant charging current of 1A until fully charged and the discharge current with variations of 0.2A; 0.3A; 0.4A and 0.5A. Experiments show that a smaller discharge current results in a longer duration of electric discharge. The cycle duration, capacity, and efficiency have decreased proportionally to the increase in the number charge-discharge cycles. Batteries with 0.2 A discharge current have shortest battery life. Batteries with 0.5 A discharge current have the greatest capacity performance. © 2019 IOP Publishing Ltd. All rights reserved.
