Put in for a replacement power pack on Friday. Just had to enter the order number from Amazon, and upload two pictures of the power pack including the model and serial number. Bought the recalled one in 2018, and it was still working fine when I charged and used it last month. Oh well, I’ll drop it off for recycle next trip to the county waste facility.

I usually use epoxy or 3M double sided adhesive tabs. This time the holes in the model I downloaded ended up being undersized, so heat setting seemed like a good plan. Guess not.
