Dynamic lead acid battery (DLAB) as a breakthrough design compared conventional lead acid batteries offers a solution to these problems. Two Dimensional (2D) DLAB simulations with surface area variations of 8 cm 2 , 12 cm 2 , 16 cm 2 and 20 cm 2 were successfully build using the principle of tertiary current distribution and Nerst-Planck Interface. The results for one cycle charge-discharge test showed that the increase in surface area succeeded in increasing the final charging voltage with a value of 2.16 V; 2, 21 V; 2.30 V and 2.32 V and increase the initial discharging voltage by a value of 1.58 V; 1.59 V; 1.60 V and 1.62 V respectively but did not affect the electrode surface concentration. Dynamic lead acid battery has high energy efficiency of 70.6% -71.5%. %U https://jurnal.unej.ac.id/index.php/RTR/article/view/23850 %J ROTOR %0 Journal Article %R 10.19184/rotor.v14i1.23850 %P 12-17%V 14 %N 1 %@ 2460-0385 %8 2021-04-30
