I’m slowly switching to rechargeable ones (Ikea Ladda ones), but we still have lots of other batteries around.
Do you have a favourite device to test them with? Ideally it could test many different types (regular, coin), but I’m ok with just AA/AAA if there is a cheap/reliable option.
When I did a search just now, I saw recommendations both for and against multimeters/voltmeters. Some said it was easier, and others said that it wasn’t accurate because of testing under load.
Thanks :)
I don’t have a recommendation for a tester, but after about a decade of vaping and dealing with 18650s, I will say it can be beneficial to keep batteries paired together (on devices that require more than one cell) during their lifespan so that you don’t have one sagging from old age while the other is still performing well. This probably isn’t as big of an issue on normal electronics that don’t have a massive current load like an ecig, but something to keep in mind. I typically never break up a pair but when I used to have several pairs of batteries, I would just use a sharpie to mark a full set “A” or “1” while the next set is “B” or “2” to avoid mixing them up.
