Read this support article and the links off it for details about your Mac, Determine battery cycle count for Mac laptops - Apple Support and where it says, "Use the table below to see the cycle count limit for your computer's battery. The battery is considered consumed once it reaches the limit." Yours has a 1000 cycle capacity so with only having use 16% you're still a long way off from needing to consider getting it replaced. Even rechargeable batteries have a finite lifespan and how long they last will partly depend upon how much you use them.
The health number is an estimate and people tend to obsess about it. Use it as a general guideline but decrease may not be linear so don't worry about a couple of percentage drop. When your computer thinks it needs a new battery it will probably tell you that.

That's pretty good. Whatever you're doing, keep it up.
