The BatteryLock™ system on a Coleman® Divide™+ 225L LED Headlamp stops battery drain, so you'll have the power you need when you need it most. On a normal headlamp, there is typically some residual drain as long as the battery is connected in the circuit, even when the light is off. With a simple pull on the front of the face, you can completely disengage your batteries, so they can be stored in your headlamp for years (up to their inherent shelf life). You’ll also reduce the toxic corrosion that can damage your headlamp. Using your headlamp is as easy as protecting it. Just slip on the fully-adjustable head strap and use the single-button to easily cycle through five modes - high and low spot to see off in the distance, high and low flood to view a wide area, and a red mode for night vision. No matter the situation, from power outages to roadside emergencies, a headlamp with the BatteryLock™ system is ready, even when you aren't.
