Thanks for the replies.

The GP3700's could have been sitting around for ages. I bought them from a local hobby shop and they had been re-packaged from another store. The price had been dropped from the original packaging.

The Intellect ones on the other hand were from a store near the city and were only received just before I got them. (I had to wait for them) I have not heard of NiMH cells going short circuit. I thought this was only common with NiCD cells.

As for the Japanese made Sanyo RC3600HV, I have downloaded the data sheets and according to the data sheets they are quite comparable if not better than equivelent capacity cells from China. After I pre-condition them I will do some tests and see how they hold up. I know when I used the standard Sanyo RC3000 cells after they were zapped and matched they were extreamly good. The new Sanyo RC3600HV cells are already High Voltage cells the same as the chinese ones.
