When a battery is constructed such that all the positive terminal of the cells are connected to a same point and all the negative terminals of the cells are connected to another point then the grouping of cells in this manner is called the Parallel Grouping of cells. The two end terminals of the construct where all the positive and negative terminals of the cells are connected act as the corresponding terminal of the battery.
