Invention of the day: The ABC Holder

[RoGeorge]

Tadaaam!!!  Proudly presenting ... [drumroll] ...  The ABC (Any Button Cell) Holder! 



Proof that it can hold any button cell:



Almost forgot about this one, was very useful while measuring the mAh left in various types of button cell batteries after a couple of years of shelf storage.  (Or for trying out of curiosity to recharge them, and guess what, they didn't  .)

I recently needed an ABC clip.  Since I'm lazy, I didn't build anything, I just used a Kelvin clip.

That's a nice hack. 
(I don't have any Kelvin capable instruments, so no Kelvin clips either)
