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 :)
If you want to just test voltage (and not capacity) a standard volt meter will suffice. If you are wanting to test rechargable batteries for their capacity then you will want to cycle them with recordable device that will count the AmpHour (or miliamphour) for discharge and then charge. For this I use an opus3100 tester. Or RC battery charger /discharger
