Whee, another PRS-950 owner, and the new/replacement battery doesn't charge. US model with PRS+ 2.0.18 and Device 2.0.00.11300. Thank you to who posted the Hackaday link gives me something to think about while I wait on a reply from the seller for this battery.
For disassembly of the 950, it's pretty easy IMHO, but I have a little experience and the right tool. If you have a glasses screwdriver and a thin "spudger" (something to pry with, my pocket knife uses utility/box cutter blades and I used that), you have the tools. The service manual is already posted here:

If you remove the 4 screws on the left side, that trim piece slides Down (with some force the first time) and then simply lifts away. The back cover has 2 screws that are hidden by the left edge piece. The manual makes it look like the back cover slides, but it doesn't. This is where you pry, gently and little by little, around the edges. I think I did the top edge first, then the bottom. The back then lifts away/sort of hinges on some tabs along the right side (from the front, left as you're working on it with the reader face down). The battery is then front and center. The connection comes straight up, though it's hidden by a foam block (to keep it pressed in place?). The battery itself is held in place by double-sided tape, and it's STICKY. This was the worst part, I suggest using something wide to pry under the edge and then Lift with... a 2" putty knife would work, plastic would be even better but those tend to be thicker.
The chrome bezel that runs around the outside, which the video shows coming off the PRS-650, STAYS IN PLACE. Similarly, there's no reason to remove the screw found under the stylus.
I've never done video before, but maybe I'll give it a shot and post it up (for the dozen PRS-950 owners still left).

Here's my attempt at a video showing the disassembly of the PRS-950 to gain access to the battery.
