Most devices & gadgets are rechargeable nowadays. The only thing I have that still requires batteries is a headlamp but even those are available in rechargeable varieties. House smoke detectors need a battery too.

That does raise another issue: some of the retail-grade chargers are pretty terrible and may have led some people to a bad impression of how rechargeable batteries perform.
A charger should charge cells individually, at a reasonably fast rate, and terminate correctly to prevent overcharging. Yours hits two points out of three: it’s individual and correct, but slow.
