Okay, I have taken the "kindle battery surgery" pictures requested in another thread, and here they are..
Not sure which kindles these fit, other than PW2 and PW3. Unlike earlier kindles with 4-pin battery modules (some with labelled clock and data wires, these are 3-pin battery modules (perhaps using "1-Wire" protocol?).

This is the battery from a PW2 (identical to that in my PW3), with the outer label peeled off, and the metal "tray" removed. It was inflated (like most dead LiPo batteries). I tore the foil pouch opening it. I hope the gases I inhaled were not TOO toxic. :o

Here is a cropped closeup from that the photo above, showing circuit details.

This is with the internal LiPo battery flipped up to reveal more of the circuit board inside the battery module. The metal battery tabs are spot-welded.
EDIT: The wrinkles you can see on the deflated battery foil jacket (above) give an indication of how puffed up it was when still inflated.

This is a closeup of the circuit board, taken from another viewing angle, so you can see under one of the battery tabs. I could not get a good focus (cellphone camera) when I tried to photograph the text on the ICs. The sunlight needs to hit it "just right" to even see the text on the chips (too small to read with MY naked eyes). That blue-marked black band on one battery tab just looks like a shrink-wrapped label to me.
The battery in your Oasis photos looks different to me. However, I suspect that the same method may be useful to replace its INTERNAL LiPo cell with a cheap replacement, keeping the circuit board and battery module frame intact.
BTW, instead of uploading photos to Imgur (or wherever) as in the past, this time I uploaded them to my MobileRead profile, where I created a photo album in my user control panel. Those photos are embedded above. No worries about external links suffering bit-rot (as in some of my OLD posts here, now with dead photo links in them) this way, eh?
