If you use a “fast” charger with typical rechargeable cells, you’ll shorten their lives rather quickly.

Spend just a little more money on a better charger, and you’ll save a lot of money on your cells.

I have one of these: https://www.lacrossetechnology.com/bc700/index.php

Not only does it recharge AA’s and AAA’s, it will even bring some “dead” cells back to life (well, somewhat…)

However, the OP is primarily about Lithium-ion batteries, like you find in cell phones, laptop computers and electric cars.

I’d check your charger OKIsItJustMe Jul 2016 #2

So far, I've found rechargeable batteries only useful for remotes. For that they are great! brewens Jul 2016 #3

They work great for me! (Your mileage may vary.) OKIsItJustMe Jul 2016 #4

It was suggested to me to buy some enloops too. passiveporcupine Jul 2016 #7

Eneloop. Amazon. (n/t) thesquanderer Jul 2016 #9

Reportedly, the Amazon Basics cells are rebranded Eneloops OKIsItJustMe Jul 2016 #12

Good info, thank you. I have a handful of led flashlights that I use AAA batts in, jtuck004 Jul 2016 #8

The charger I linked to above will tell you the capacity of your cells OKIsItJustMe Jul 2016 #15

Only useful for remotes? iPhones, laptops and the like wouldn't work without them. thesquanderer Jul 2016 #11

Brewens is likely thinking of NiMH’s or NiCd’s OKIsItJustMe Jul 2016 #13

I'm just talking about a cheap charger for AA and AAA that I got like nine brewens Jul 2016 #16

Today’s Low Self-Discharge NiMH cells are much better than your old rechargeables OKIsItJustMe Jul 2016 #17
