why are there different sized batteries (aaa-D, etc) if they all put out the same 1.5v?
In: 394
A bigger battery won’t fit in smaller device, and a smaller battery won’t provide as much power for as long as a bigger one.
Or with bigger words: Energy storage capacity (Watt-hours) is affected is mainly by size, whereas potential (voltage) is affected mainly by battery chemistry (e.g. Alkaline 1.5V, NiMH 1.2V, LiPO 3.7V etc.)
