I have a Canon 7D, original version. I have a pair of Canon EP-E6 batteries and a pair of Wasabi LP-E6 batteries. I use a Mieke MK-7D with my 7D. Today, put my freshly recharged Canon batteries back into the battery pack and found my recharge performance only one bar. Does that mean that my Canon batteries are due for replacement. My Wasabi batteries shows three bars when I recharge them. Is it bad to leave batteries in the camera when not in daily use or for a couple of weeks? I am not sure why my Canon batteries drop down to one bar so soon.
