Rebuild G4 TiBook battery

[timoog]

Before I order the cells, has anyone had success with this? looks possible going through the threads but not explicitly called out. Have to reset the eprom as Techknight mentions? This is for the M8244G/B M8511 type.

According to Chans Battery Rebuild in Canada, it can be rebuilt. The one I sent them had a bad board, though, and was not rebuildable, so I cannot confirm what they told me.

I, too, would like to know if the eprom needs to be reset, and also how to go about doing this.

Hi, my first post and the rules aren't readable because the server's having kittens so I hope I'm not breaking any rules by necroposting.
I've got a 1MHz DVI TiBook and stupidly I threw the duff battery away. It seems to be throttled because of this, according to what I was told on Macrumours PPC forums, running at 667MHz instead of 1GHz.
I've built ebike batteries, have got a spot welder, qualified in electronics and would like to get a duff battery to rebuild to get the max out of my PowerBook.
I do have a 3s2p battery from an iBook with what looks like the same connector, but the TiBook wants 4s2p so I suspect the pcb will be different. Anybody out there got an old battery, or info on how to fool the TiBook into thinking there's one connected?
Thanks.
