Electrolyte concentration is one of the important parameters on Lead-Acid Battery (LAB) outcome. Lead-acid battery has been made with static and dynamic electrolyte treatment where 4 variations of electrolyte concentration (20%, 30%, 40%, and 50%) and 1A current applied in the system during charging-discharging test to analyze the relationship of the electrolyte concentration to the battery characteristic and compare static and dynamic lead-acid battery performance. The experiment results that the capacity of dynamic lead-acid battery increases along with the higher concentration from 20% to 40% but decrease at 50% compared to 40% for 3 first cycle charge-discharge test. The static lead-acid battery unwork at concentration 20% and show the increases capacity along with increases concentration. In capacity and efficiency point of view, dynamic lead-acid show better performance compares to a static lead-acid battery. Both electrodes show that there is a new phase form during the discharge process.
