How Long Is 2.5 Amp Hours. This means that the 40V trimmer will operate for a little over three times as long on a single charge as the smaller 20V unit. For the sake of this explanation lets say you have a 12 volt fridge with a compressor motor and this fridge draws 5 amps while its compressor motor is actually running now if the compressor motor ran continuously for the whole hour the fridge will have drawn 5 amps in total for that hour and we express this as 5 Amp-Hours 5Ah and so if it ran like this continuously for 24 hours it.

For example if you have a 2 Ah battery rated at 5 V the power is 2Ah 5V 10Wh. Batterycapacityexplained whatisbatterycapacity whatisamphour whatiskilowattho. So no more confusion on how to calculate battery life.
Nominal Voltage X Amp Hours Watt Hours.
KWh 2400 1000. Nominal Voltage X Amp Hours Watt Hours. For example lets convert 20 Ah at 120 V to kWh. 20 x 0333 667AH.
