Abstract
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 ().
