Quick Answer

To replace the battery in your Radiant RH1 or RH2, open the battery compartment, remove the old rechargeable lithium ion battery, insert the new one with correct polarity, and close the compartment securely.

Why Battery Replacement Matters

Over time, all rechargeable batteries lose capacity. Replacing the battery in your Radiant RH1 or RH2 restores full runtime, ensuring your headlamp is ready for expeditions, emergencies, or everyday tasks.

Using the correct replacement battery is important. The Radiant RH1 and RH2 are designed to work with the Nite Ize Rechargeable Lithium Ion Battery, which is lightweight and built specifically for these models.

Before You Start: Safety and Preparation

Always turn off the headlamp before opening the battery compartment. This prevents accidental activation and reduces the risk of short-circuiting.

Work in a clean, dry area. Avoid touching the battery contacts with wet or greasy hands, as this can affect performance.

Step-by-Step Battery Replacement

  1. Turn off the headlamp: Make sure the headlamp is switched off before you begin. This prevents accidental light activation and reduces electrical risk.
  2. Open the battery compartment: Locate the battery compartment on the back of the headlamp and open it according to the manufacturer's instructions. If it's secured with a screw, use the appropriate tool. Check for any debris or corrosion inside the compartment before proceeding.
  3. Remove the old battery: Gently slide or lift the old rechargeable lithium ion battery out of the compartment. Avoid pulling on any wires. Dispose of the old battery properly—do not throw it in regular trash.
  4. Insert the new battery: Align the new battery with the correct polarity (matching the + and – markings) and slide it into place. Ensure it sits flush and makes solid contact. Double-check the polarity before closing—reversed polarity can damage the headlamp.
  5. Close and test: Close the battery compartment securely, ensuring it is sealed properly. Turn on the headlamp to confirm it works. If the light doesn't turn on, reopen the compartment and check the battery orientation and contact.
