Refurbished Canon DSLR batteries are selling on eBay claiming the same performance as brand-new batteries. I took a chance and purchased one of these because it was selling for less than 1/2 the price of a brand new one. When I got it in the mail today, I immediately inserted it in my camera (Canon 6D). I went to the menu and it showed the battery was 93% charged, shutter count was at 7, but the recharge performance was red instead of green. I'm wondering if that's an issue ?
