what does mAh mean
Best Answer: mAH means mili ampere hour. It is a measure of the energy storage capability of the battery.If the battery is rated for say 1000mAH, then it is capable of delivering 1000mA for 1 hour. If the battery were rated for 2000mAH then it could deliver 2000mA for 1 hour, so it would have twice the energy capacity of the first battery.If you know what your load takes-for example 100mA, then a 1000mAH battery could sustain this load for 10 hours (1000/100).f the battery were rated for 2000mAH then it could deliver 2000mA for 1 hour, so it would have twice the energy capacity of the first battery. If you know what your load takes-for example 100mA, then a 1000mAH battery could sustain this load for 10 hours (1000/100).
