Jade738 really changed my mind on the free money angle here.

Have you ever noticed how those knockoff batteries also seem to swell up after a few weeks? I made that mistake once with a cheap battery for an old camera, and it literally got stuck inside the thing. Had to pry it out with a butter knife, which was terrifying. It's like these companies just slap any old lithium cells together without any safety circuits. Definitely learned my lesson about going cheap on anything that holds a charge.

I keep mine for years until they crack or melt in the microwave.

Read somewhere grief is love with nowhere to go - makes more sense than any checklist.

Used to swear by label makers but that sounds brutal.
