The battery was almost fully charged at me and seems to be comparable to that of the capacity forth with the original battery.
/ Update after about half a year: have now several case had these batteries on a several month trip through South America, they have properly doing its job - any of these batteries, I have now determined a dozen times with the Patona charger via USB Power Adapter charged - in between time and again the original Sony battery. I can see so far neither wear (less charging power) still make a difference for the Sony battery. Here, then, can be accessed without hesitation not only in view of the much lower price.
