Are the 9v batteries lsd (low self-discharge)? more importantly, are they 9.6v or 8.4v? only respond if you know.

Yes, they're low self-discharge (LSD). They're 7-cell units (8.4 V nominal).

Is it 10000mAh in total, or per individual battery?

D capacity is 10000mAh per battery. if you put two in parallel you get 20000 at 1.2 volts, if in series you get 10000 at 2.4 volts.

How would these perform in low temperature? I would need them to reliable work close to 0C (32F)

according to a chart here http://nordicgroup.us/battery/ a NIMH battery at 0C will have 80% of its room temperature (25C) capacity.

For the 9V battery - what are the exact dimensions (without posts) and how many recharge cycles are they rated for?

The ones I received measure 48.3 (45.3) x 26.5 x 17 mm (the 45.3 is the shoulder dimension you requested; full dimension offered for other readers). Oops: Description says 1,000 cycles (as "times"). I'd last thought it unspecified.

best getest

diverse merken getest waaronder ook Duracel en Varta. Deze steken er kop en schouders bovenuit. Al 2 jaar doen ze wat ze moeten een gaan duidelijk langer mee dan alle concurrenten. Aanrader dus.

Rechargeable batteries

Good batteries, had some charge in them when delivered. Take about 8 hours to charge fully using the power owl charger. Saves me so much money, not having to buy batteries for my daughter’s toys. Last about the same time as regular batteries before needing to be charged up.
