Near Death Experiments in... Batteries?

[NT2C]

So, while moving some stuff in the garage today I came across the empty kitty litter pail I'd used to clean out the cab of my old white truck when I traded it.  Pawing through long-forgotten (and replaced) items I came across a pack of batteries at the bottom.



Wait, does that date say what I think it says?



Yep, some nearly 11-year-old 123A lithium batteries.  I wonder how well they held their charge?  They spent at least 7 years in the cab of my truck, in temps from well below freezing to well over 100F, then spent the last few years in my garage. 

Let's find out!





How about that?  Full bars on both of 'em!
