Yeah, it's a shame how many electric toothbrushes I've had to throw out when the batteries go bad. Good brands also, but they don't make them serviceable. Since I'm in a hurricane zone, I have flashlights with 18650 cells. more cells than flashlights. Worst case scenario is that I can't get gas for the generator and the power is out for a week or whatever (and if you read my previous posts I'll solve that problem soon) I can charge batteries from my off grid backyard solar. My current problem is that comcast/xfinity goes out more than the power flickers. I can't wait for buried fiber on my street to come one day.

Correction on that, the lithium polymers such as in modern cellphones are a fair bit different. NMC was used in non-LiPo cells for early mobile devices, however, was a thing in many variants.
NMC can still be found in things like handheld power tools.
Today, Li-Po (Lithium Polymer) and LCO (Lithium Cobalt Oxide) are typical options for mobile devices.
I was thinking more along the lines of things like early laptops that switched off nicad/nimh while looking at devices on my desk
Back when we spent quite a bit of cash on camcorders, we experienced plenty of NiMH batteries. It's quite an inferior battery, but it served its purpose well, at the time.
I still find NiMH batteries shipping in modern gear today, e.g., low-end electric toothbrushes. I generally avoid these where possible, and buy Lithium-based toothbrushes :-).
