Petzl's Headlamp Comparision Chart Petzl rechargeable battery Unlike alkaline cells, which fade gradually, the Petzl rechargeable battery maintains its intensity until it fails. It may be recharged up to 1000 times, so it's much kinder to the environment. And it's the world's best for reading in a tent, or a bed, even with a hood or a hat on. It uses just two AA alkaline cells, and comes with a standard bulb and a spare mounted on board. Halogen bulb optional.
