Good afternoon, I recently picked up an 80D bundle and with it came a couple aftermarket batteries. For whatever reason the aftermarket batteries will not power the camera. No lights, lcd, or anything. Pop in the OEM battery and the camera comes to life. The batteries were all charged with the canon charger and reflect having a full charge. These are the Green Extreme GX-LP-E6N batteries. Has anyone else had trouble with aftermarket batteries in the 80D? I use a pair of aftermarket batteries in my 20D and they've been working great, but they are a different brand. Thanks.
