Official Replacement Theradome Battery – UK Delivery Only

If your Theradome has stopped working or is only lasting for a treatment or two per charge, it’s quite likely you need to replace the battery. Theradome GB are one of few suppliers of the official Theradome battery in Europe. Our batteries contain a safety cut off chip that detects power surges, generic batteries don’t have this.

Please be aware that fitting your Theradome with the wrong battery (even if it looks similar) may damage your helmet and render it unrepairable.

The Lithium Ion battery comes complete with Theradome connection clip and wires attached. We include instructions on how to change the battery correctly. Batteries are guaranteed for minimum of 12 months.

How to Change a Theradome Battery

Step 1: Disconect your helmet from the charger.

Step 2: Locate the two screws that fasten the battery door on the blue underside. Remove them and don’t lose them.

Step 3: Carefully remove the battery door. The battery is attached via two wires and a white plastic connector. Disconnect them by holding the wires close to the connector and pull up. Slide the battery out.

Step 4: Connect the new battery to the white connector.

Step 5: Once the new battery is plugged in, the helmet will say “system error” and the master switch light will flash red. Click the master switch and it will say “system resume.”

Step 6: Reinstall the battery door. Take care not to pinch the wires. Fully charge the helmet before using.

Step 7: Recycle old battery.

If your Theradome is still not functioning correctly after replacing and charging please contact us for troubleshooting or possible repair.
