MacOS – New battery installation in the Macbook Pro

It sounds like you've got a bad battery, no doubt, and should have it replaced, gratis. While this shouldn't be a problem, it won't hurt to have the most ammunition possible when you arrive at the store or have to place a call to Apple Care. Take a screenshot of the "Service Battery" menu icon (Shift + command + 3), and collect all the data you can (like the kind you've included in your question). I've had three defective batteries replaced by Apple, two of them close to the 300 cycle mark, which is what Apple guarantees 80% battery health to. The screenshots and data have been instrumental in getting a rapid, no questions asked replacement. Of course, if your battery is showing the health problems that it is after only six (!?!) cycles, then you've got a good shot at it anyway.
Good luck!

Something like

system_profiler SPPowerDataType | grep "Cycle Count" | awk '{print $3}'

should do the job.

system_profiler SPPowerDataType | grep "Condition" | awk '{print $2}'

will get you the battery condition, for example: Normal.

If you want more output, run:

system_profiler SPPowerDataType | grep -A3 -B7 "Condition"

to get something similar to this:
