Charging time is one of the important things for secondary batteries due to the effectiveness of the battery on charge storage, especially on the dynamic battery. A dynamic battery is a new type of secondary battery with an electrolyte flow from an outside chamber into the battery by using a pump. Dynamic flow battery has been built using Pb and PbO2 with a size of 22.5 × 7.5 cm2 as electrodes and 30% H2SO4 solution as an electrolyte. Variations of charging time was conducted on a dynamic lead acid battery with variation 0.5 h, 1.0 h, 1.5 h, 2.0 h, and 2.5 h at constant electric current 1 A. The result shows that dynamic lead acid battery single cell has secondary battery character that can be charged at voltages of 1.92-2.17 V and discharged at voltages of 1.97-1.81 V. Experiments show a linear relationship between charging time and battery capacity. The longer charging time, the larger the charge stored in the battery. Charging time of 0.5 h can hold charges until 630 mAh and a discharge time until 0.55 h while a charging time of 2.5 h can hold charges of 3838 mAh and a discharge time 3.83 h. © 2018 Author(s).
