How Many Hours Does A 1500 Mah Battery Last. The determining factor is the number of shots that you fire. Up to 5 hours max depending on laptop battery consumptionrate.
As you might remember from our article on Ohms law the power P of an electrical device is equal to voltage V multiplied by current I. Therefore if a battery has a battery capacity rating of 2000mAH it can supply 2000 milliamperes of current during its lifetime. The only way to really find out is to time it and the simple calculation dividing the mAh capacity by the mA supply 1500500 3 hours is a pretty good rule of thumb and a far more pragmatic way of estimating the time.
This is a car battery not a deep-discharge marine battery.
If the load is 500mA the cells usable capacity actually drops to approximately 1500 mAh and 1500500 is only 3 hours. This is a car battery not a deep-discharge marine battery. If the load is 500mA the cells usable capacity actually drops to approximately 1500 mAh and 1500500 is only 3 hours. 10000 mAh - 4 days.
