MacBook Pro Battery Calibration

Is it normal to have to calibrate the battery more than once? I have performed the calibration procedure at least 5 times now and what happens is during the discharge, it will get ~63%, then jump to 7%. I am getting about about 3 hours, 47 minutes of usage before full discharge. Is this normal? Of course, SMC and PRAM resets have been performed. https://d3nevzfk7ii3be.cloudfront.net/ig...

However, the recharge shows a nice, incremental charging percentage.

I just can't get the hang of uploaded screen shots here. I have noticed that each time I do this calibration procedure, the percentage gets close to actual before dive bombing to 7%. Today, it made it to ~ 43% before diving to 7%

Thanks, Mayer! The image from Battery Health 2 is posted. The red bars are hours using the battery, Yellow is charging and Green is fully charged. Of course, Grey is powered off.

@mayer I had no idea Coconut was free. As requested, the image from Coconut has been posted.

Well that battery looks to be in good shape and is lasting about the standard time.
