Weigh it - how does it compare to the original? Take it through a full discharge cycle and see how much charge it holds; a typical trick by shady companies is to use smaller or fewer cells. It is VERY unlikely that Sony sells cheap batteries through "YHR store", which must be at a little shady, since they probably counterfeited or stole the ID chip. And if the battery catches fire on an airplane and melts a hole through the fuselage, you must buy the airline a new plane ... if you survive. :-) Seriously, we should do some testing, review collecting, and xray imaging and learn where the various knockoff battery companies land on the good-to-garbage spectrum, and buy from the good ones ... if any. In a plug post a few years ago, I wrote about rebuilding laptop batteries with new cells. I learned that TSA takes a Very Dim View of user-rebuilt batteries (which can hide a deadly amount of explosive) and will prosecute amateur rebuilders. Sigh. We can wish for a TSA-certified laptop battery rebuild company, but we should wish for a nation of ambitious hardware entrepreneurs first.
