MAINTAINING LEAD ACID BATTERIES

What is the use of 4 volt lead acid battery

In the discharged state, both the positive and negative plates become (PbSO 4), and the loses much of its dissolved 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. Common applications for 4V batteries include telecommunications, UPS, medical equipment, aerospace, and more. [pdf]
