Conventional headlamps experience residual power drain as long as batteries are connected to the circuit, even when the device is off. With Battery Guard, the batteries are automatically disengaged from the circuit when the headlamp is turned off to extend their life by as much as 25%. This technology also reduces the chance of damaging corrosion so batteries can be stored in the device for years (up to their inherent shelf life).
