Triple-A batteries are smaller and slimmer, usually getting used for smaller gadgets that do not want as a lot energy. Conversely, double-A has extra power and is used for bigger electronics that require it. However outdoors of their dimension and energy functionality, these batteries are comparable sufficient to be interchangeable so long as we are able to make the battery match into the slot — which is the place aluminum foil comes into play.
Aluminum foil is a conductor, that means electrical energy can cross by it. Due to this nifty truth, aluminum foil will can help you bridge the hole left between a triple-A battery and the double-A battery slot.
