1.4.1 Lead Acid Battery – Basic Description And Electro-Chemical Reactions
1.4.1.1 A Lead Acid battery consists of a number of 2 V nominal cells (actual voltage of the cell is around 2.105 V)
that are connected in series e.g. a 12 V nominal battery will have six, 2 V nominal cells in series (actual approximate
voltage of the 6 cells will be 2.105 x 6 = 12.63 V). Each 2 V nominal cell in this battery consists of an independent
