I recently replaced the battery of my Macbook Pro (Ventura 13.7.1) 2017 model. A new battery A1708 was installed. Do I need to calibrate the battery? If yes, how do I actually calibrate the battery? I tried googling for answers but they are long time ago. Thank you in advance.
MacBook Pro 13″, macOS 13.7
The "fixit" sites say that it should be calibrated by charging it fully, waiting a couple of hours, draining the battery completely, and then charging it fully again. I cannot verify that such a procedure is necessary or advisable. Perhaps someone else here with more detailed knowledge can say for certain.
Regards.

For a third party battery that procedure is absolutely essential or the battery may degrade very quickly. In fact when the laptop powers off at 0% charge, it is essential not to leave it sitting unplugged for too long as that can degrade the battery especially on the first time. Once the battery is charged to 100% the second time, it is essential to leave the power adapter connected for another two or three hours before using the battery normally.
An original Apple OEM battery repair does not require this calibration/exercise. I think Apple does this at the factory so the battery is ready to go, but the third party battery manufacturers do not (probably to save time & money, after all why not make the user work for it).
If you had an Apple OEM battery installed by Apple or an AASP, then no calibration or exercise is required.
If you purchased & installed a third party battery, then yes you need to calibrate/exercise the battery properly or the battery will likely quickly degrade. @varjak paw correctly listed the procedure although I did add a few extra notes to my other reply to @varjak paw.
FYI, the quality of third party Lithium batteries is extremely poor. The best options are from OWC or iFixIt, but even those batteries are not always perfect.
I would suggest running the Apple Diagnostic after you finish the calibration procedure to see whether the third party battery is able to pass the diagnostic while it is still brand new & presumably as healthy as it will ever be. Some third party batteries may not pass the diagnostic even when brand new because they may not be reporting certain information to the system or perhaps is reporting incorrect information. If the diagnostics passes now, then later on if you run it & it fails the battery, then that may be a useful indicator (maybe...).
Do I need to calibrate a new battery A1708 installed in my Macbook Pro?
