9V SSD NiMH battery recomendation needed

[captianworkbench]

I would like some input from the people here on 9V NiMH rechargeable batteries.

And first let me limit the conversation to NiMH only. I know there are several lithium 9V batteries out there now, but I would really like to stick with the SSD NiMH.

Also, In the past, I have had several different 9V NiMH batteries. The earliest ones were only 7.2V and were quite dissapointing. A couple of years ago I invested in a couple of the Powerex SSD 9V battereis that were 9.6V (8-series). They have worked well, but a few devices I have do not like the higher voltage. Off the charger, these batteries can be over 12V.

So, I am leaning toward the Powerex/Maha 8.4V (7-series) 9V battery for my next purchase.

I am looking for thoughts on something similar, such as other brands to try or something like that.

Thoughts?

7 cell seem to be best compromise. I have some in meters and vintage pocket radios. As they die off i have been getting 2s li ion .do not get the usb ones if you are putting them in radios or any other rfi sensitive equipment.
