What to Do When You Hear a "Battery Low" Message

If your Theradome PRO or EVO announces a "Battery Low" message outside of normal use, follow the steps below to determine whether the issue is related to the battery, charger, or both.

1 Step 1: Inspect the Charger and Charging Port

Before troubleshooting further, visually inspect the following components:

  • AC adapter
  • USB charging cable
  • Theradome charging port

Look for any visible damage, loose connections, bent pins, or worn cables that could affect charging performance.

2 Step 2: Verify the Charging Status

  • Plug your Theradome into the charger and check the master switch indicator.
  • The master switch should eventually turn solid green when the helmet is fully charged.

A Scenario A: The Helmet Reaches a Solid Green Light

  • If the master switch becomes solid green, but you continue hearing the "Battery Low" message, the charger is working correctly.
  • In this case, the battery may need to be replaced.

Replacement Needed

New Battery

New Charger

B Scenario B: The Helmet Never Reaches a Solid Green Light

  • If the master switch does not change color after approximately 30 seconds, or it never becomes solid green after 4 hours of charging, the issue may involve both the battery and charger.

Replacement Needed:

New Battery

New Charger
