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’ve always used a multimeter and never had any problems with it
Batteries can show good voltage on a multimeter but then drop immediately once a load is applied if they’re failing.
I was going to say this as well. A multimeter is good to have in the house for certain situations and since they’re pretty cheap (~$20) it’s a good investment if you ever need to test fuses or voltage, continuity, etc.
