I just got a new pair of Wasabi Power NP-BX1 batteries for the HDR-AS30V helmet camera, charged them up, and ran them through the CBA:
The new ones (H and I) cost near twice as much as the 2-1/2 year old previous pair (F and G), while delivering less energy at a lower terminal voltage. Tested ’em twice to be sure and the curves overlay just about perfectly, so it’s not a fluke.
The rep assures me the replacement cells will deliver their promised capacity. We shall see.
