Today I've tested two 9 volt batteries by using my tongue. I wonder if I'm the only person that does that 🤔 😛 🔋

Lol, glad to hear I'm not the only one 😊

@vbradio I've been doing it all my life. Recently I found USB-rechargeable 9Vs that actually cost just a little more than throwaways.

@the_turtle Oh nice, gonna have to look that up

@vbradio Only when I need to know if my 9v battery is dead or not!

@vbradio no. I was curious, and did a blind bench test. I found out I was able to guess a 9V batteries voltage to within 0.5v.

I think that precision is amazing, I was..... shocked....

I would not want to be called out on this, could I do it again? so much pressure.
