A battery life extender for a portable lighting device employs a reconfigurable mechanism operable to selectively electrically isolate one or more batteries from a circuit having a parasitic power drain. For example, a lighting device includes a light generating element, at least one battery, a user operated switch configured to control delivery of electrical power from the at least one battery to the light generating element, and a housing assembly supporting the at least one battery and the light generating element. The user operated switch can impart a parasitic power drain. The housing assembly is reconfigurable to: (a) a first configuration in which the user operated switch is electrically connected to the at least one battery, and (b) a second configuration in which the at least one battery is electrically isolated and the at least one battery is retained by the housing assembly.
