MQ Power Battery NP-FW50 FW 50 f. SONY NEX-3 NEX-5 NEX-6 NEX-7 Alpha SLT-A33 SLT-A37 SLT-A55 (Electronics)
The Sony Alpha had many problems to recognize the battery. Lost after a relatively short time (about ten times charging) quite a bit of life and was after a year ready for disposal.

I see no difference between this "no-name variant" and the original battery by Sony. The term corresponds to that of Sony batteries. Bleit seen whether he quickly gives up the ghost.
