I got an email this morning from Glenn Pugh sharing this article, and I wanted to pass it along. I had no idea how bad the Canon, Nikon and Sony counterfeit battery situation was. Be careful when buying “brand name” because you may be buy a total fake. For more info check out this article from The Digital Picture’s website.
I can’t speak for other camera batteries but I have found this off brand battery to be the a great compatible chipped LP-E6 battery.
Thanks for the heads up Glenn!
