I have a tester for AA/AAA/PP3 batteries and fuses, but it does not test button batteries.
I know you can get them on Amazon & e bay etc. I've recently got a card of AG7 batts for my magnifier. I don't know if the batteries are old stock or the tiny bulb has gone.
I tried to test the button batteries using an LED. It lights up using a 9v PP3 batt but not 3xbutton batts.
