My dremel's battery stopped working 🪫and the battery packs are no longer sold so I rebuilt it 🔋 I have had this dremel forever, it's not my main dremel which is corded but it's nice to take to the hobby shop build nights. I've had it for many years, every few years I'd buy a new battery pack for it when it would stop holding a charge but I can no longer find them anywhere so I rebuilt it.

Nice work. I always try to repair rather than replace when I can. 👍
