After studying other reviews I chose this one, the - was yet rated better - albeit more expensive.
I have now compared the two batteries (original, but exhibition camera) on several occasions and had to realize that this stops here a lot longer, which should of course be that this one has more capacity than the original. We had a whole day and I could do with this battery about 100 photos over the other. Is of course to other settings, etc., but you can tell the larger capacity but very fast.
Charged the battery is in a short time, which lasts depending on the discharge 2-4 hours, I have not measured accurately. So is comparable to the original.
If appreciable things crystallize at continuous operating out, I will update my Rezi.
Conclusion:
So far, I'm impressed by the spare battery, especially since he has more "juice" than the old. From me 5 stars.
