Understanding how to replace your Theradome battery

Step 1: Make sure your helmet is disconnected from the charger.

Step 2: On the rear of the helmet, you’ll locate two screws that fasten the battery door. Remove them with a Phillips screwdriver and set aside in a safe place.

Step 3: Carefully remove the battery door from your helmet. You’ll see the battery is attached to the helmet via two wires and a plastic connector. Disconnect them by pinching the wires on the base of the connector and pulling the wires out gently. Slide the battery out and set aside.

Step 4: Connect the new battery to the connector. Make sure the two connector ridges are facing outwards. Slide the battery connector into the board connector and slide the battery into the slot.

Step 5: Once the new battery is plugged in, the helmet will say “system error” and the master switch light will flash red. To get out of this mode, you will need to press the master switch one second and helmet will say “system resume.”

Step 6: Reinstall the battery door. Do not turn on the helmet until the battery door is shut and the two Phillips screws are reinstalled. Your battery replacement is completed.

Step 7: Recycle old battery.
