15 year expired battery, 5.5 month update

Some of you might remember that I came across a battery from 2004 that somehow still had charge. I decided to do what any logical person would do, find out how long it would last for. So I decided to use it to power my mouse. This was back in May, so is it still working?

You bet it’s working! While it’s lost some of its charge, it’s still plenty of power for my mouse.

So I’m going to keep using it and we’ll see just how long it lasts for.
