I ordered some Samsung batteries off eBay and, even though I haven't read about them being cloned, think I received clone batteries. I've had them charging for 6+ hours and they haven't taken a charge. Also, the sticker that's on my older batteries is silver with black printing and was at one time a single sticker. The sticker on the new battery is white, the printing is off-center, and looks like it was cut out by hand. I'm wondering if I got taken. I emailed the seller who has reputable feedback but haven't heard back. Has anyone heard of fakes being made?
