AirPods 1 and 2 have cylindrical batteries that plug directly into the body. We need to use Hot Air Gun with helical wind to heat the metal cap to remove the battery.

Please be noted that vertical wind can’t be used since it is too concentrated and can easily damage the case.

Set the temperature of the Hot Air Gun to 100℃ and airflow to 7. Switch to helical wind.

Place the AirPods 20mm around the Hot Air Gun and heat the metal cap for 3 minutes. During the heating process, we need to flip the AirPods constantly to heat it evenly.
