What do you refuse to get generic versions of?
Definitely! For electronics, Eneloop batteries are worth every penny. I think I have ~10 AA and AAA, and I haven’t bought disposable batteries in years. I try to make sure I have 4 of each available at all times so I don’t have to wait for them to recharge. I’ve tried cheaper (Amazon) batteries, and they fail much more quickly, and sometimes swell to the point where I have a hard time removing them.
Some people say IKEA’s batteries are just rebranded Eneloops, but I haven’t had a chance to try them
