Rebuild TiBook's Battery

Well, after this thread: http://www.applefritter.com/node/4555 I got interested in the idea, and since my old battery only holds a charge of around 20 minutes figured It'd be worth wile. But I have a few questions before I even attempt to rip the old battery apart.

Will this (http://batteryspace.com/index.asp?PageAction=VIEWPROD&ProdID=945) 2400mAh cell work with a TiBook? Or is there something better/more appropriate?

Assuming that that cell would work would the old battery recognize the new cells correctly as they would be bigger than the I believe 2000mAh cells that were in the old battery? Or would only part of the new ones be used?

Also, pretty simple question, how many cells actually are there in a TiBook's battery? 4, as that would equal the 14.4V or is it 8 or something more? (Wondering for cost considerations.)

And lastly at this point, aside from having a fire extinguisher next to me and being careful soldering, (would buy the cells with tabs already..), are there any other major safety considerations to take into account? Yes, I've read up on Li-ion batteries plenty, but no site I've found specifically lists the necessary precautions.

Thanks!

Wow, those are some crazy pic

Wow, those are some crazy pics, thanks!

Guess it's a bit more complicated than I thought with 8 cells all crammed in there, but what else is there to do with an old now useless battery?

One question though. How did you get the battery apart? Seems pretty solid to me.

Razor blade and a lot of forc

Razor blade and a lot of force. Like I said it didn't go back together. They put glue on the cells too. Everything is glued together. About the only thing to do with it would be to take out the circut board that has the leds on it. They might be usefull for something down the road....

the problem with those....

The problem with those batteries is that they are highly tempramental. To make shure that the battery is not under or over charged, the circut board in the battery monitors the cells carfully. This board is pretty spicific on which cells it will use, and the only thing I could recomend is to put new cells with the exact specifications as the old ones. Ones w/ more mAH may be not charged correctly, or discharged too much (with the possible side affects being: heat, fire, and smoke; not good!). Good luck, but also be carfull.
