- Have a bunch of button/coin batteries and don’t know if they are any use? Well, watch this video and know for yourself how to test one and make sure you’re confident that you wanna throw it away.
Please be mindful that the button cells come with two different voltages. 1.5V or 3.0V.
You know nothing about this and come out with this misleading video.
Ok
Thanks for the video
It might work, but it doesn't tell if the battery is weak or fully charged. It' important since charged batteries are held sometimes for a while and weaken and perhaps the button battery is put into something more crucial - like a car key fob to start it.
It is usefull vedeo .It is what light and what volt tell me .
Crap!
3:00 testing batteries.
