This review is from: STK's Sony NP-FW50 Battery 1500mAh - for Sony Alpha NEX-5, NEX-3, NEX-C3, Alpha A55, Alpha A33 (Electronics)
I was looking for a backup battery... not too expensive! I got it! This is a quality product
that works as well as the original. I have never had problems with 3rd party batteries. I
never buy the real cheap-o batteries, because they don't have enough profit to put good
stuff in the battery. These batteries have the good stuff: Japanese cells, precision made
cases, and chips that work.
