5d mark iii battery error

[gacemite]

Please I need help my 5d mark iii showing battery error while the battery is fully charged, and I tried the same battery with 7d its work fine

I later put CF card and the camera work fine, immediately SD card was added it off again, so I have decided to be CF card till the time that I will send the camera for repair. I think SD slot has issue and a technician said I should not insert SD again till I av it repair so that the board will not be damaged.

The camera is not working fine with CF card inserted into the camera, but when I insert SD card, the camera off and didn't come up, so the camera only work with CF card and I test shoot some footage and play back with CF card which work fine but SD card still don't allow the camera to come up,
