Battery Cell Compatability??

I have a 2004 Prius and need a battery rebuild, I see where there are some battery cells being sold and listed as being for various years of gen 2 and gen 3 Prius. I have available a 2012 Prius C for a donor battery, (totaled, but still has the battery) So the question is are the cells or battery packs the same across the gen2 & gen 3 cars.?

 

I just found an informative thread on here for this topic.. Now my question would be how many cells are in a prius C battery pack?

 

Thanks a lot for clarifying that, I looked everywhere to try to find out how many cells were in a Prius c. I definitely did not want to mix gen 2 and gen 3 cells, I was attempting to find out how many more I needed of the gen 3 cells to make a whole set of 28 for my gen 2 Prius. Another thread mentions not to mix 2 & 3 cells because there is a diffence in them, not in fitting but in their resistance or something. I couldn't check the c battery until I get it to take it apart, which I was holding off on just to do the math to see how this would work out.
