Why is my Fenix flashlight not working with new batteries?
A flashlight can stop working for many different reasons. There could have been a manufacturing error, a circuit could blow, the switch could break, or it could be caused by damage during use. If your flashlight is not turning on we recommend that you first check the batteries in another device if you have one available. Even if the batteries are new, they could still be defective. If you confirm that the batteries work in another device then the problem is being caused by something in the flashlight. Please visit the troubleshooting page for your model and try any available troubleshooting steps. If the light is still not working, please contact our customer service department. Thank you!
