If your Apple AirPods or AirPods case have short battery life or no longer holds a charge, Apple now offers battery service for the AirPods, AirPods Pro, and AirPods Max. Apple can fix or replace the battery on your AirPods or case. If you are under warranty or have AppleCare+, it is free, and if you are not covered, it will cost a fee depending on your AirPods model (see chart).
To start an AirPods battery service request, schedule an appointment with your local Apple Store or schedule service online through Apple support. Apple support is pretty quick and AirPods service are usually completed within a week.
