How to calculate the life of a 3000 mAh battery?
For example, if you have a 3000 mAh battery that runs at 0.2 Amps (0.2Amps = 200mA), then the time that the battery will last for is (3000)/ (0.2*1000) = (3000)/ (200)= 15 Hours. If instead of the current you have voltage and watts, then the formula is (mAh*Volts)/ (Watts*1000) = (hours).
What does Mah stand for in a battery?
