This article examines lead-acid battery basics, including equivalent circuits, storage capacity and efficiency, and system sizing. Stand-alone systems that utilize intermittent resources such as wind and solar require a means to store the energy produced so the stored energy can then be delivered when needed and the resources are unavailable.

The lead acid battery uses lead as the anode and lead dioxide as the cathode, with an acid electrolyte. The following half-cell reactions take place inside the cell during discharge: At the anode: Pb + HSO 4 – → PbSO 4 + H + + 2e – At the cathode: PbO 2 + 3H + + HSO 4 – + 2e – → PbSO 4 + 2H 2 O. Overall: Pb + PbO 2 +2H 2 SO 4 → 2PbSO 4 + 2H 2 O. During the
Lead acid batteries are built with a number of individual cells containing layers of lead alloy plates immersed in an electrolyte solution, typically made of 35% sulphuric acid (H 2 SO 4) and 65% water (Figure 1). Pure lead (Pb) is too soft and would not support itself, so small quantities of other metals are added to get the mechanical strength and improve electrical properties. The

Lead acid battery comes under the classification of rechargeable and secondary batteries. In spite of the battery''s minimal proportions in energy to volume and energy to weight, it holds the capability to deliver increased surge currents. This corresponds that lead acid cells possess a high amount of power to weight proportions.

3.3 Battery Self-discharge The lead acid battery will have self-discharge reaction under open circuit condition, in which the lead is reacted with sulfuric acid to form lead sulfate and evolve hydrogen. The reaction is accelerated at higher temperature. The result of self-discharge is the lowering of voltage and capacity loss.
When the lead acid battery is discharging, the active materials of both the positive and negative plates are reacted with sulfuric acid to form lead sulfate. After discharge, the concentration of sulfuric acid in the electrolyte is decreased, and results in the increase of the internal resistance of the battery.
