Which AA Battery Last The Longest?

Harbor Freight sells two store-brand batteries. The Thunderbolt Magnum came in last place, and the Thunderbolt Edge came in first place. I saw another video with similar results.

Most of these are likely made in China or other countries.  Any brand could change the materials or even the manufacturer from one year to the next.
