MacBook – 2015 MacBook Pro battery replacement at Apple store

Typically Apple will replace (instead of repair) a computer that has required 3 repairs for the same issue.

It may require a call to Apple Care (800-273-2273) and ask to have the case escalated. If you have taken it to the store already, and the store has refused to replace, then Apple Care will probably back the store's decision. If however you call Apple Care first, and when they say to take it to the Apple Store for repair, you question the need for 3 repairs on the same computer for the same reason, ask to have it escalated, you will probably get offered a replacement.

If that gets you nowhere, You may also try a EECB (Executive Email Carpet Bomb) to various service level contacts. sjobs@apple used to get results, may try tcook@apple.com now? Or do google/consumerist search for EECB and Apple. http://consumerist.com/2007/05/11/how-to-launch-an-executive-email-carpet-bomb/

Most likely, the battery is the issue. However, there is no way a battery should last only 65 cycles before it died. Most likely you have a defective battery.

Even if you don't have a warranty, Apple will probably give you a new battery if you complain, since the current battery died way before it should have. They usually cover obvious defects even if the computer is out of warranty.

The other possibility is that the previous owner had something done to the battery at some point, and the work was done incorrectly. 65 cycles seems abnormally low for a 2012 laptop, unless the previous owner never used the computer.
