This, entirely. I remember back 10, 15 years ago, rechargeable batteries were trash. Gave them a second shot recently, and I'm genuinely surprised. They're as good, possibly even better than, non-rechargeables
One thing to note is that many of the cheaper rechargeables do not work very well with older electronics.
This is because the nominal voltage on alkalines tend to hover around 1.6 volts when they're fully charged whereas on rechargeables they tend to hover closer to 1.4, and that may not seem like a lot but when you've got something that uses six AA's and you short it out the equivalent of nearly one full battery then things are bound to get a little wonky.
I've been using NiMH batteries for a long long time now. Very few devices dislike them at this point. Some will show the "battery low" icon but keep working as they typically have much higher charges than alkalines.
The set I have (Duracell) is at least 10 years old - the charger has "copyright 2009" on it fwiw. Not sure they hold a charge for quite as long as originally, but they work for what I need (TV remote, RGB lighting remote, beard trimmer). I can only imagine how much better they have gotten!
