AI Customer ServiceA battery with highly sulphated negative plates will eventually only accept a surface charge, resulting in a false positive high state of charge readings. In this condition, a battery may appear fully charged but have a very low capacity, as expressed in Amp Hour (AH) or Reserve Capacity (RC).
When the battery is recharged, a current (conventional direction) is made to flow into the positive electrode of each cell. This current causes the lead sulfate at the negative electrode to recombine with hydrogen ions, thus re-forming sulfuric acid in the electrolyte and Spongy lead on the negative plates.
The battery consists of two lead plates, one coated with lead dioxide and the other with pure lead, immersed in an electrolyte solution of sulfuric acid and water. When the battery is charged, a chemical reaction occurs that converts the lead dioxide into lead sulfate and the pure lead into lead sulfate as well.
When a lead-acid battery is charged, a chemical reaction occurs that converts lead oxide and lead into lead sulfate and water. This reaction occurs at the positive electrode, which is made of lead dioxide. At the same time, hydrogen gas is produced at the negative electrode, which is made of lead. During discharge, the reverse reaction takes place.
In a corroded battery, much of the current gets lost to resistance (in the form of heat) as the grid wires become exposed and/or disconnected from the active materials.
When the battery is discharging (i.e., supplying a current), atoms from the spongy lead on the negative plates combine with sulfate molecules to form lead sulfate and hydrogen. As always, electrons are left behind on the negative plates so that they maintain a negative potential.
