Hi,
I keep thinking about this a lot, and I've actually remembered this time to post!
I have a 13" rMBP from 2014, that still has the original battery. It spent much time on power, and then about a year sat from fully charged to discharged. It recharged fine, and I continued to use it. I then was a bit more careful and switched it off at 80%. It sat another 6 months like this.
It was then used on mains, so fully charged, and has spent the last year just sat.
Given how old this unit is, I'm starting to get paranoid about the battery. It hasn't done that many cycles (a couple of hundered at most I think). I'm going to dare to try and power it sometime today and see what the status is.
If the Mac reports good battery health, is this accurate, given the age of the system? I will charge it outside as a precaution, and because I have become increasingly paranoid about battery fires in general.
Is it worth considering changing the battery purely based on age, or is battery failure mostly predicated upon charge cycles and chemical condition from use? I know Li-Po (I think that is what is in this one) degrades with time, but it is unclear as to what causes a dangerous condition, or whether they are all incendiary devices just waiting to fail.
There is otherwise nothing wrong with the unit, so if I can keep it going another decade, I'll be quite happy!
