The quickest way to see whether your MacBook's battery is in good health is by clicking the battery icon in the upper-right corner of your computer's screen while holding the option key. But if you want a deeper dive on your battery's status, the System Report will provide an overview with information like the number of cycles your battery has left and its full capacity.
Does it actually show cycles remaining? I can only see cycles already used. IIRC the batteries are usually good for about 1000 cycles but obviously there's variation in that; my first battery on this laptop only lasted about 300 before needing replacement under warranty.
