This is a 4-cell battery; before opening it up, I was under the impression that it was a 3-cell.
The charge controller circuit board has "LIP8198" and "1-867-277-11" markings in the silkscreen, along with a strip of Kapton tape over the top of the PCB.
This is a nice item that I found today at Princess Auto... A grey box hiding on the bottom of a grey shelf. The phrase "Demo Kit" caught my eye, and I had to take a peek inside. I was blown away by the beautiful innards, and I just had to have it.

Ok, so not really a project, but just to show off, here's the newest addition to the party going on in my camera bag.
Well, this was funny for me solely because my laptop's battery lasts less than 60 minutes. So, 60 minutes / 100% = 0.6 minutes (or 36 seconds) for 1%. At 0%, I really don't know how much time is left. Yet I was able to take the pic, and save it in paint before the laptop died.
Funny how those things go.
