I'm new to photography and just got my first dslr less than a month ago. After some random shooting sessions and getting to know more about the camera, i wanted a battery grip so that portrait mode shooting can be done comfortably. Being a student and wanting to save some money, I bought a used original canon battery grip from a person in this forum today. Battery grip as stated in the thread was mint condition bought a month ago. During the deal he installed the battery grip for me and showed me that it's working. After seeing that I checked the physical condition of the battery grip, found scratches so he gave me a discount and bought it from him. I checked it again when I reached home and realised that the camera couldnt commnicate with the left slot from the grip, battery level couldnt be shown. I did some research on the net and found out some others have this battery communication problem too. I tried both original and third party battteries but only works on the right slot. I asked him if he knew about it and he said yes and told me it isn't a problem and doesnt affect the performance. I asked for a return as the item isnt in the condition as stated in the thread and I wanted a perfect working grip but was rejected and ignored.
Moral of the story: buy brand new if possible.
Can this battery communication problem be solved or repaired?
Thanks in advance!
