A closer look at the internal battery, which is actually several groups of series-parallel circuit the battery, in general, by a single laptop battery battery capacity and voltage requirements of the constraints, notebook batteries are generally connected in series with the first approach to ensure parallel voltage and battery capacity, analogy, if a nominal 12.5V, Battery laptop battery 4000MAh laptop batteries, in general, this is composed of: start with three single voltage of 4.2V, 2000MAh batteries in series to achieve the standard said the 12.5V voltage, and then as a group composed of the battery cell and then in parallel circuits, increase the overall capacity of the battery to 4000MAh, this battery is generally referred to 6CELL battery pack.
