Sony NP-FV70 vs NP-FV70A
 

Does anyone have real-world data comparing Sony's NP-FV70 and NP-FV70A batteries? I have the former myself and wondering if it would be worth switching to the latter.

From documentation I have found, the 70 is rated at 6.8 to 8.4V and 1960mAh. But the 70A is 7.3V (a bit under the average of the 70) and only 1900mAh. B&H's specs are also a bit strange regarding weights. 51g for the 70, but 89g for the 70A. From these specs, one would assume the 70 is better.
