Ella’s above-referenced portable and foldable keyboard stopped charging around near its third birthday. Since its manufacturer warranty had elapsed and it was broken and the manufacturer doesn’t sell or recommend any replacement parts, I found it free game to open up and inspect. While inside, I started a guide for others. Please help improve the guide, I didn’t take enough pictures and didn’t write enough describing what I did.

The great thing about gaining access to the inside of the keyboard is that I found a location to repurpose one of the hundred or so vape batteries I’ve accumulated over the last couple years. The vape battery I put in doesn’t use all the space that it could use, but that’s ok. It’s sort of a proof-of-concept and if it seems to work I’ll find a better matching battery later. Optimally I’ll find a 403525 (that’s 4.0 mm x 35 mm x 25 mm).
