Official Replacement Theradome Battery – UK Delivery Only

If your Theradome has stopped working or is only lasting for a treatment 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 chip that can detect if there has been a helmet safety issue and prevent current being suppled. This is an extra safety measure on top of many others which enables us to deem this device safe to place on your head.

The Lithium Ion battery comes complete with Theradome connection clip and wires attached. It is not possible to fit a standard battery to your helmet. We include instructions on how to change the battery correctly. Batteries are guaranteed for minimum of 12 months.

What If The Battery Doesn’t Rectify The Problem

If you should purchase a replacement battery and find it does not rectify your Theradome, we are happy to give a refund (minus postage) on return. We are also able to fault diagnose and in many cases offer a repair solution if changing the battery is not the issue. Please get in touch if you need fault diagnosis or servicing.

We cannot send batteries outside of UK by airmail. If you live outside of UK please contact the manufacturer for batteries, chargers, troubleshooting and repairs.

We include a replacement Micro USB with all batteries. Micro USB Cables wear out with use. If you have been using your Theradome for more than 2 years, please throw away the old cable when you get the new one as worn out cables can cause ineffective charging or damage to your helmet.

If you need advice or troubleshooting please don’t hesitate to get in touch.

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. Press 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.

Step 8: Charge with your new Micro USB cable, included in your service pack and throw the old cable away.

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