I needed new batteries for my pepper grinder, and ended up going down a vast rabbit hole.
First, I purchased 15 different brands/models of Alkaline AAA batteries from Amazon. (This cost about $150, which means that I strongly overpaid to run a pepper mill.)
The spreadsheet with the raw data and calculated results for the tests is available on Google Docs:
And you can watch me further discuss the spreadsheet as well.
YouTube user autismspeaks brought up a good point about name-brand batteries having a lower self-discharge rate than cheaper batts.
So I decided to set a pair of each type aside for a few years (except for the Rayovac Industrials because I’d only bought an 8-pack and used all of them).
Whether I’ll ever get back to it? That’s another matter entirely.
