Reply to comment by ToxiClay in eli5: Why do seemingly all battery powered electronics need at least 2 batteries? by OneGuyJeff

That's interesting because I have two wireless mouse. One of them requires two AA batteries and the other one requires one AA battery.

So if one mouse can work on 1.5 volt why can't the other one, given its basically the same product.

Different electronic componets operate at different voltages. If you use only 1.5v components you can build a mouse that only needs one.

Or you could step up the voltage to 3V (or 5V or whatever you need) internally. But these days you can probably get stuff like Bluetooth/wifi chipsets that can run on very low voltage for exactly this kind of usage.
