ABSTRACT:

BACKGROUND OF THE INVENTION
The present invention relates to a battery charging, and more particularly, to a battery charger which charges an extra or stand alone battery as well as a battery within a flashlight.
Rechargeable batteries systems are well known in the art. Also, rechargeable flashlights to charge the batteries within the flashlight are likewise well known in the art. Several battery recharging systems include housings to place the batteries within the housing to charge the batteries. While these systems are satisfactory for recharging batteries, these systems do not indicate when a power failure or loss is present. Also, these systems do not provide illumination of the charging flashlight when the power failure occurs. Further, these systems only recharge the permanently enclosed rechargeable batteries.
SUMMARY OF THE INVENTION
Accordingly, it is an object of the present invention to provide the art with a battery recharging system which, while AC power is flowing to the charger, enables charging of an extra or stand alone battery as well as a removable battery within a flashlight. The present invention provides indicators to inform the user if one or both batteries are in a charging mode. Also, the invention provides an indicator to inform the user that a power failure is present. Likewise, during a power outage, the flashlight with battery, if connected to the charger, is illuminated so that it is readily available to the user.
In accordance with one aspect of the invention, a battery charger comprises a housing including a receptacle in the housing to receive a stand alone rechargeable battery. Also a receptacle is present in the housing to receive a flashlight, which includes a removable rechargeable battery. A first electrical contact is in the housing to electrically cooperate with the stand alone rechargeable battery. A second electrical contact is present to electrically cooperate with the flashlight to recharge the flashlight battery. The recharger includes a charging circuit. The charging circuit includes a first charging circuit for charging the stand alone battery. The first charging circuit includes an indicator to indicate charging of the battery. A second charging circuit charges the flashlight battery. The second charging circuit includes an indicator to indicate charging of the flashlight battery. The charging circuit also includes a first power outage circuit which includes an indicator to indicate a power loss or outage. A second power outage circuit illuminates the flashlight bulb, when the flashlight with battery, is in the housing, when a power loss occurs.
Additional objects and advantages of the invention will be apparent from the detailed description of the preferred embodiment, appended claims and accompanying drawings, or may be learned by practice of the invention.
