I keep my MacBook 12" plugged in at all times except when I'm not on the computer then I unplug it from the outlet. I drain the battery once a month since getting my MacBook June of last year. I'm wondering about the 92% health and also about the age 1.8 years is that really the date the battery was put in my MacBook?

My MacBook is exactly 12 months old. The battery is showing 90% Health, I leave it plugged in all the time at the moment. I am thinking of getting that app that tells you when to unplug to get better battery longevity.

Better to unplug it when the battery is full. Let is go up and down a bit. Don't drain it (if you mean to zero). I let mine go down to about 20% (not frequently) and don't leave it plugged in when battery is full.

I use Coconut battery to monitor my battery and to compare it with other MacBooks.

Your questions:

92% health is fairly normal. It will likely go up and down a bit.

Age 1.8 years: Sounds like the MacBook and battery was manufactured long before you bought it. Maybe sat in the seller's store room. My MacBook (2016)'s battery is about a month older than the MacBook which was built a few days before shipped - but I did buy it from Apple and that may help.
