Why purchase ExtremeWolf?
It has the same dimensions and best quality. Many "no name" rechargable batteries promise high capacity. This capacity loses, however, often immensely after some loading cycles. Our battery was designed and concepted in Germany. We promise you sustainable performance at a reasonable price. We would like to wish you many happy hours with your camera!
I use them in Sony A7R II and they work as good or better than original Sony batteries that came with a camera. I liked them so much I ordered 4 more. AND GUESS WHAT? One of the 4 batteries was defective. So I write to seller asking to replace defective battery and they just ignore me. Batteries are good but seller sucks. I'll return whole package for refund although 3 of 4 batteries are good.
Was worried the batteries wouldn't work because they weren't OEM, but just what I wanted and no problem's.
Work well and no issues, would be 5 stars but battery life seems a little less than with the original Sony packs and these are supposed to have better capacity.
