I use rechargeable batteries in everything now - with the exception of smoke detectors. As time goes on, I have to keep buying more batteries because I keep accumulating battery-powered devices. It seems that more devices are using AAA. I bought about a dozen little LED flashlights that take three AAA each. That was probably a mistake, although they work great.
In ordering another sixteen AAA batteries I was surprised at the choices. Eneloops are about twice the price of generics, and I've had good luck with the Amazon NiMh batteries, so I avoid the Eneloop brand. Amazon weren't available, so I ordered sixteen Bonai 1100 mAh AAAs. The more mAh, the fewer charges the battery will take. Some go down as low as 500 charges before failing.
I just looked on Amazon, and they have lots of their batteries for sale today, although they don't say they're NiMh, but they must be.
What someone has to develop is a replacement for the explosive Li-Ion battery.
I use eneloops exclusively. They will hold a charge for a long time, where most others I have tried over the years will self-discharge over a week or two. To me that is well worth the additional cost.
Looks like batteries have gotten a lot better since I switched (I’ve been using eneloops exclusively for pushing 10 years if not more), but the eneloops are still holding their own.
I went to eneloops several years ago and have only had to add to my supply due to the increasing number of devices I have. Never had one go bad or refuse to recharge. Highly recommend eneloop.

I agree. I don't use a lot of rechargeable batteries but have tried several brands through the years. I bought a set close to a year ago and put them in my camera bag as a backup for the Die-hards already in use. The other day I decided to check them just to see how well they held a charge. They were still 75% charged after somewhere between ten months and a year.
One of the problems with LiON is that if you try to charge them when they are too cold, you destroy them. You also MUST have voltage over/under charge circuitry (typically built in to the battery itself), or you will destroy them that way as well...

I’m not quite there — I believe I have had 2 fail in a decade or so — out of hundreds (yes, really! a quick mental tally has me at about 140 and I am sure I am overlooking quite a few).

They are not cheap but in my experience, LiON is the way to go they hold a charge a LONG time!
Part of the issue is whether they will be used right away. Much of the advantage dissipates if you charge them just before you use them.
Lion batt are not the explosive ones LiPo are the explosive ones
Don’t run a nimh dead you will never get it to take a charge
