eli5: Why do seemingly all battery powered electronics need at least 2 batteries?
In: 107
Also, a single alkaline battery at 3v, if in the same form factor as a AA batter would have double the voltage, but half the capacity. You’d still want two batteries.
Essentially, 1.5v is a legacy voltage that we keep. Higher voltage, assuming same chemistry, would be at the expense of capacity, assuming the form factor stays the same.
Or simply put, watt-hours would be the same regardless.
