Just bought some new batteries for my PowerBook Duo 2300c, and they're probably bad anyway, but I can probably recell (replace the NiMH cells inside them) them if someone knows how. I found a good tutorial for type Is, but I think these are type IIIs. Are they mainly the same, or completely different. I also found the cells in the type III batteries are 1600mAH, but would it be bad to replace them with 1850mAH (or greater), or would I not get any more time out of them anyway?
