Originally posted by BigMackCam The capacity is highly unlikely to be as advertised, and the resulting battery life will almost certainly be quite considerably lower than that of a genuine D-Li90.
What he said ^^^
I use two Wasabi in rotation with a Pentax D-Li90 with my K-3 and with my use patterns, all three work well. That being said, I have noticed that the Wasabi have lower capacity, especially if I am doing a lot of live view or video work. My original pair of Wasabi from when I bought the K-3 (2014) sort of petered out and were replaced this last summer. I am still using my original Pentax battery.
