Odd numbers of batteries… AAARGH!
I have a question for those who design electronic devices which are powered by disposable batteries. Why do you design your products to use three batteries?! Do you actually shop for batteries? If not, you won’t know that you cannot buy batteries in packages with odd numbers of cells. You can get two packs, four packs, and any of a number of other packs with an even number of batteries. What the hell am I supposed to do with the odd battery that’s left over? Should I wait until I’ve bought three packages of batteries and then use the three “left-overs?” There’s not something you could cut out or redesign to drop the voltage requirement just enough to use two batteries?
