Many 14-inch notebook, you may use 2 and 4 stringsof 8-cell hybrid mode, the voltage will still be 14.4V, capacity is doubled to4400mAh, to ensure a longer usage time.
而很多14寸以上笔记本，则可能采用2并4串的8芯混联方式，电压依然为14.4V，容量翻倍达到4400mAh，保证更长的使用时间。
If the resistance is doubled without changing the voltage, the current bees only half as strong.
如果电压不变，电阻增加1倍，电流就减小二分之一。
