Calibrate Canon Battery 1DX MK II ?

I have a Canon 1DX MK II with the Canon LP-E19 batteries. One battery shows a message that the battery needs calibration. When I put the battery in the Canon charger (LC-E19) and press the calibrate button it doesn't seem to want to calibrate. The calibrate light blinks a few times goes out and then quickly blinks the 14 hour, 4 hour, 2 hour lights and then is lights steady indicating fully charged. The long discharge process doesn't occur. What is the best method to calibrate a battery? I have another Canon LP-E19 and it doesn't give the calibrate message. Also both batteries show fully charged when viewing the battery info data. Thanks for any help.

I have this same exact problem with the same battery, been trying for months to sort it, I put it in the charger and waited for the green light to blink, tried pressing the calibrate button, nothing, I ten tried it by holding it down and it then finally did the whole discharge and take 18 hours to recharge, stuck it back in the camera and it still gives me the message to calibrate it, any help would be appreciated here too.

That happens routinely with my 1D Mark 4 (same battery), and also happened with my buddy's 1Dx2 that I used for a while. . The best thing, I've found, is to just ignore the stupid calibration recommendations.

When I put a battery into the charger, and it starts giving me that red light blinking thing, I just unplug the charger, take the battery out, plug the charger back into the wall outlet, put the battery back into the charger ... and then normally just the green "charging progress" lights blink. . If the red light still blinks, I just repeat the unplugging process until just the green lights blink.

In all my years of using 1D series cameras, I have always completely ignored any kind of recalibration recommendations, and have never had any problems as a result. . I suspect that the whole recalibration thing is mainly just something to discourage people from using 3rd party batteries, and not something that is integral to the actual performance of the camera or the batteries.

Canon is strangely over-protective of their batteries and wants them to be proprietary. . They even go so far as to refer to 3rd party batteries as "counterfeit". . Ha ha ha! . They go to strange lengths to try to make it so that 3rd party batteries won't work in their cameras, and sometimes these odd measures make it more complicated to use the Canon brand batteries, too.

Have not experienced this. Guess the alternative is to buy a new battery ?

Im wondering if this is an Age thing and amount of times its been charge thing that canon has built into their programming

First I have heard so thanks for posting

I believe that canon is overly protective of their batteries as well. This is a "pro" battery so maybe canon needs to be extra protective as it gives them less liability.

This thread is old, but I can add anyway that the calibration sequence is there to improve the ability of the camera to predict the battery's charge life. Today's cameras have battery meters indicating the remaining capacity in percent, not just full, not so full and empty. For the percentage to be reasonably accurate you need to calibrate now and then. Apart from that, the battery itself works the same.
