AppleCare covers the replacement of a MacBook Pro battery if it drops below 80% capacity before 1000 cycles. I have until the end of the year and I'm at 81% and 300 cycles. It would be nice to get a new battery in exchange for the $379(?!!!) I spent for AppleCare. I'll get an extra year of warranty since I purchased it on my American Express, but I would like to get something out of what I paid for AppleCare+ rather than pay $200 for a new battery and harass my credit card company into reimbursing me.

Any thoughts on what to do? Will Apple give me a new battery if I tell them I'm 1% away?

What’s the harm in asking them to diagnose your battery and not even say anything about wanting a free swap? See what they say and document they had a chance to diagnose things before the warranty ends.

My feeling and expectation is Apple would not offer to replace things unless you have them perform diagnostics and they see something amiss or feel it’s about to fail. I also see +- 5% FCC estimate when I run things from day to day, so I wouldn’t worry about +- 1% either to be eligible for a swap on the pooled plan (you are pooling risk - so it’s not free, it’s paid for out of the pool). It’s also not free since you would waste a 80% good battery that might last for years if your assumption that the only thing wrong would be measured capacity below 80% FCC within 3 years of delivery.

The 80% FCC is the standard, so it’s understandable for you to look at things around that as a line, since Apple established that design line and goal, but in practice, 60% FCC still gives a lot of run time and sometimes it’s not even worth paying for batteries below 40% or less. For some needs 40% FCC is perfectly serviceable and causes no real harm.

AppleCare plans are pro-rated and you’re paying for the term benefit (just like paying in for insurance of any kind) and no one gets to collect for “close to needing care” or a refund if you don’t use the benefit. Of course, you can cancel the coverage any time before it ends (and then the return is pro-rated). If you really think through the coverage, I think you’ll join me in “not wanting to get something for your payments” since the FCC is just one aspect of performance.

I would hope Apple wouldn’t replace the battery unless they feel it’s not performing, so I would just get it service diagnosed now and then about 2 weeks before the end of the coverage (or anytime you see 75% FCC). Since Apple can run diagnostics remotely , you can get a quick diagnosis and chance Apple would want to swap out parts (maybe something other than the battery needs service).

In the end, I gladly pay for battery service when it’s needed and if it takes 3 years to get to 80% FCC you might have another 1-3 years before the charge falls off and only have AppleCare and a $90 or so service for 6 years of productive use of a Mac spanning one original battery.

So in the end I would recommend:

  • read up and learn what the numbers mean
  • talk about the trade offs - some are being green, some are being frugal and not wasting time / resources / materials
  • balance the potential harm if you don’t get it serviced - your time is also valuable - driving in or having to go back for a repeat test also wastes resources
  • my experience is that when batteries are just being exhausted, they don’t fall sharply and any 5 to 9% change is meaningless to the eventual out of service date.
  • my experience is that when batteries fail, they plummet in days or weeks and Apple still covers them even after since they were at 85% and now are at 45% within a short period of the end of warranty.
  • My MBP's battery is at 78.5% (6874 of 8755 mAh; shown by ioreg -brc AppleSmartBattery), 3 days before the protection plan expires, but apple is not willing to replace it. The diagnostic tool of the Apple Authorized Service Provider shows 81% without showing any concrete values.

I had a similar situation: Apple's diagnostics revealed that battery was failing, but not failing enough to warrant a replacement.

However, by smiling sweetly, and asking nicely, and joking with the Store guy, he went to his boss to ask if they could take it in anyway. They did.

So, that's worth a shot.
