A full charge on the battery is rated for 6 hours with the white light on high, 20 hours on low, 60 hours for the red light, and 48 hours for the SOS.

I have had all sorts of headlamps over the years, but none have impressed me as much as the Mantus Headlamp from Mantus Marine. It’s built around a rugged, watertight, aluminum-alloy case that houses a rechargeable and replaceable battery. The included 2600 mAh, 3.7-volt lithium-ion battery takes a full charge in about 3 hours. The single LED light, mounted in the middle of the housing, has a high output of 770 lumens, a low output of 150 lumens, an SOS beacon light, and a red light setting for preserving night vision.
The head strap can be switched out for a smaller strap to attach the lamp to a wrist or a PFD.
