Voltage of lead acid battery upon charging. The charging reaction converts the lead sulfate at the negative electrode to lead. At the positive terminal the reaction converts the lead to lead oxide. As a by-product of this reaction, hydrogen is evolved.
The battery should not, therefore, be discharged below this voltage. In between the fully discharged and charged states, a lead acid battery will experience a gradual reduction in the voltage. Voltage level is commonly used to indicate a battery's state of charge.
Lead acid charging uses a voltage-based algorithm that is similar to lithium-ion. The charge time of a sealed lead acid battery is 12–16 hours, up to 36–48 hours for large stationary batteries.
A lead acid battery consists of a negative electrode made of spongy or porous lead. The lead is porous to facilitate the formation and dissolution of lead. The positive electrode consists of lead oxide. Both electrodes are immersed in a electrolytic solution of sulfuric acid and water.
Figure 4 : Chemical Action During Discharge When a lead-acid battery is discharged, the electrolyte divides into H 2 and SO 4 combine with some of the oxygen that is formed on the positive plate to produce water (H 2 O), and thereby reduces the amount of acid in the electrolyte.
Lead acid batteries must always be stored in a charged state. A topping charge should be applied every six months to prevent the voltage from dropping below 2.10V/ cell. With AGM, these requirements can be somewhat relaxed.

The six cells are connected together to produce a fully charged battery of about 12.6 volts. That''s great, but how does sticking lead plates into sulfuric acid produce electricity? A battery uses an electrochemical reaction to …
In the discharged state, both the positive and negative plates become lead(II) sulfate (PbSO 4), and the electrolyte loses much of its dissolved sulfuric acid and becomes primarily water. Negative plate reaction Pb(s) + HSO 4(aq) → PbSO 4(s) + H (aq) + 2e The release of two conduction electrons gives the lead electrode a negative charge. As electrons accumulate, they create an electric field which attracts hydrogen ions and repels s…
