How Many Watts Does A Aa Battery Have. A typical AA battery contains about 39 watt-hours or 00039 kilowatt-hours which is plenty of energy to keep your small flashlight bulb lit for hours before you have to change the batteries. AAA batteries can be measured using voltage for the most part.
So volts times mAh is energy in milliWatt hours. The AA battery or double-A battery is a standard size single cell cylindrical dry batteryThe IEC 60086 system calls it size R6 and ANSI C18 calls it size 15. I suspect that youll get 12V which is why youre considering a 12V gel cell.
They are rated at 15 volts each and depending on the battery will depend on how much wattage is produced from those volts.
It seems on average that AAA batteries have a measurement of a bit less than 2 watts per battery. If you arrange them in parallel it will provide you with the same energy as a single cell. So volts times mAh is energy in milliWatt hours. The Open Circuit Voltage no load voltage of the 15V AA Duracell Alkaline batteries is 16V though it quickly drops to 15V under load.
