Inserting and Removing PRO's Lithium-ion Batteries
Align and insert the battery in the battery slot on the underside of the Theragun PRO with the flat side of the battery end facing the circular release button. Battery life is displayed on the PRO’s OLED screen when the device is turned on. The PRO is fully charged when the OLED screen shows 100% and the battery icon is full. To remove the battery, press the circular release button above the battery slot and pull the battery out.

Charging
Plug the charging wire into the port on the charging dock. Insert the battery into the charging dock and press down until the light flashes. Charging is complete once the light stops flashing.
