Hi everyone,

I have two Canon LP-E4N batteries for my 1D X, I calibrated them whenever I got the recommended message, one of them started to show the "calibration message" even after I did the calibration. Does any one know how I can get rid of that message, and how important is calibration? My 1D X is 4 years old, with very low mileage about 15000 clicks and I alternate between the two batteries and both of them still have 3 bar performance level with no drop on battery performance.
