I do one cycle to start the battery, but it was not enough for this battery. Being a 8 cell battery it has a rather high voltage. There is a small capacity difference between the two batteries.

Conclusion

Using 8 cell 9V gives the highest voltage of any 9V batteries, but NiMH do not have very impressive capacity at 9V. The battery is not specified for low self discharge, this means that it will selfdischarge in a couple of months.
These cells are good for application that needs high voltage and has frequent battery replacement.
