how much is a large energy storage battery per watt
Watt Hours Per Battery-Calculation, Lithium Battery and cr2032
A 4400 mAh battery with ll.1volt means divide the rating mAh by 1000. It means you must first get the Ah rating. So divide the mAh rating by 1000. It is 4400/1000= 4.4ah. Now calculate as 4.4Ah x 11.1 volts = 48.8 Wh. While a 12V 50Ah battery calculation is 50 Ah x 12 volts = 600Wh.
