ABSTRACT:
A rechargeable flashlight is also provided. The flashlight includes a housing having a battery compartment and a light source adjacent a first end of the housing. A rechargeable lithium-ion battery provides power for the flashlight. A controller circuit serially connected with the battery is operable to control the flow of electricity to and from the battery. Specifically, the controller circuit is operable to disconnect the lithium-ion battery cell from the light source in response to the charge in the lithium-ion battery depleting below a pre-determined lower threshold. The control circuit is further operable to disconnect the lithium-ion battery cell from electrical connection with the first charging contact when the lithium-ion battery is connected with a battery charger and the charge in the lithium-ion battery reaches a pre-determined upper threshold.
