I'll admit right of, I do not. Most my battery needs are met with donations from my mother. She literally brings me a freezer bag full of AA batteries that are mildly used when I need some. I think she gets them from the hospital where she works. They work great in the few things I use batteries in which amount to game controllers, remotes, and my toothbrush. For other sources of batteries I usually just buy disposable alkaline ones. For instance, last night I needed to replace the 9v battery on my IR thermometer.
Anyway, I ask this because I've been thinking of at least replacing the non AA batteries I use with NiMH batteries. I just found out that
Harbor Freight carries
these things now, and of course, being from there, they aren't incredibly expensive either IMO.
So, what do you guys do?
