Abstract

A battery recharger that can be used with a standard flashlight having a flared head and a generally cylindrical body includes a recharger unit that accepts flashlight batteries for recharging and a clamping structure that grasps the flashlight where the flashlight head joins the flashlight body and exerts enough clamping force to support the weight of the recharger unit when it contains the batteries. Substantially all of the flashlight body is free to be used as a carrying handle and also to be used as a lever arm to remove the flashlight from the grip of the clamping structure. The recharger includes recharging circuitry that can fully charge high-performance battery sticks up to their rated power of 4.4 amp-hours. The recharger accepts both two-cell and three-cell size battery sticks, and can be moved about to whatever locations are necessary.
