WebJoules is a direct relationship, one Joule here equals one watt-second not watt-hour so to get your energy in joules you have to multiply your watt-hour in the figure by 3,600 because it’s 3,600 seconds in an hour. So if you do that and you look at a double a triple a and a double a better you triple a battery 1.4 watt-hours. green world company sas
