Back in May of 2019, I came across this battery that was set to expire in 2004. Seeing as it still made 1.5 volts, I deiced to use it to power my mouse. Well, after almost 13 months, it still works.
Looking at this voltage over time graph, we’re about here.
So it looks like I might still have a few months of the battery powering my mouse.
I missed the exact year mark as I was on vacation that week and have been busy since then. Wonder how many more updates I’ll get to provide before it’s ultimate demise.
