Ha! Same thought at pretty much the same time. Good to see you fellow elder.
Yeah, I remember having to put extra batteries in some devices, because the 1.5v AA alkalines vs. 1.2v AA NiCads add up when you need 10 of them.
That makes me wonder if there's more modern versions of the AA and AAA batteries that use the newer tech to last longer (and hopefully not leak if left alone for a while). All the ones I have here just say "alkaline" and I'm not sure if that's a category that includes newer lithium batteries or if it's just the same old tech.
Yes, you can get rechargeable lithium batteries in the standard form factors like AA or AAA. They should work for most things, but the voltage is a bit different and of course you must use the right charger. They’ve been out for quite a few years and even the main brands sell them now
