Abstract
A flashlight includes a battery compartment configured to alternatively receive a rechargeable battery or a non-rechargeable battery, a battery-type indicator located within the battery compartment, the indicator movable between a forward position and a rear position, wherein the indicator is biased to the rear position, and a switch that is closed by the indicator in the forward position, wherein the closed switch allows a battery inserted in the battery compartment to be recharged. With a rechargeable battery inserted in the battery compartment, the rechargeable battery engages the indicator and moves the indicator to the forward position, thereby closing the switch and allowing the rechargeable battery to be recharged while in the battery compartment. With a non-rechargeable battery inserted in the battery compartment, the indicator is in the rear position and the switch is not closed, thereby preventing the non-rechargeable battery from being recharged while in the battery compartment.
