Fenix E25UE Troubleshooting StepsUpdated 4 hours ago

If your light won't turn on or won't charge, be sure to remove the plastic insulation disc (please watch video) inside the flashlight body as soon as you get the light. Confirm that your batteries are good. Try using the battery in another device. Confirm that the battery/batteries are inserted into the light facing the correct direction. The Positive (+) side should be toward the head (LED) of the flashlight. Confirm that there is only one o-ring on the light. The o-ring that comes in the box is a spare. The light already has an o-ring on it when you first remove it from the box. If you put on the spare o-ring, please remove it as this will prevent the light from making a full connection with the batteries. Click and hold the power switch for .5 seconds. A single click will not turn the light on, you must hold the button down. If the light flashes twice when you press the side switch the light is in Lockout Mode. Click the side switch twice quickly (double-click) to deactivate Lockout and turn the light on. Confirm that the head piece is completely tight on the body of the flashlight. If the light only works while plugged in and/or if the charging indicator is showing constant green while it is plugged in but it is not working when not plugged in, the battery may be bad. Lubricate the o-ring using a small amount of petroleum jelly on the end of a cotton swab. After you have completed the above troubleshooting steps, if your light is still not working, visit our Warranty and Repair page (https://fenix-store.com/pages/warranty-info) to review the policy and submit a claim.
