1. Crack the sucker open.
2. Check out what cells it uses
3. Buy suitable cells for replacement(online or somewhere)
4. Have local person spot-weld the new cells to some tabs(or the existing stuff) or do it yourself if you are capable.
5. Stuff it all back in the battery's case.
6. Place battery in computer & charge & test.
7. Be happy! (optional)
I don't know how common re-celling battery packs is in the PC world but a number of Mac users have been known to do it for their portable machines that range from a couple to a dozen or so years old. I would like to assume that since Mac users have been known to do this that at least some PC users have done it before as well and you might find information for your specific hardware if you look.
*Edit
Oh, and try not to resort to soldering the cells together. Spot-welding is really the best option for things like this.
I would find out what the part number is, for your particular battery and then go to pricenetwork.ca and shopbot.ca and see who has the best price...then I would pricematch it with NCIX, should they carry it. :clap:
