Rebuilding a Laptop Battery

I have not tried this myself, but this video sure is intriguing. It shows how some guy pulls his laptop battery apart, replaces the cells and brings his laptop battery back to life. For the price of a generic laptop battery on eBay I probably would not try this, but if I had a battery and could not find a replacement I think that I'd give it a try. You'll need a soldering iron, some goggles and maybe a bit of luck to do this!
