ABSTRACT:
A battery energizer for button batteries, such as zinc-silver oxide or zinc-mercuric oxide batteries, that are normally considered unchargeable, provides for energizing of the batteries in a safe and simple manner. A solar cell having a maximum current output (e.g., 20 milliamps) is operatively connected to terminals for releasably receiving a button battery. A light emitting diode, or like indicator, provides an indication of when the battery is fully energized, and additionally assists in preventing overenergization of the battery. The solar cell, terminals, LED, and the like can be mounted on a nonconductive material mounting plate which is mounted by a suction cup and hook to a window, adjacent a light bulb, or the like. A battery charger for conventional dry cell rechargeable batteries (such as nickel-cadmium batteries) utilizes the solar cells, and LED, and a zener diode connected in parallel with terminals. An adaptor may be provided with the terminal for adapting them for use with any conventional size dry cell battery, and a simple dummy battery may be utilized so that less than the full complement of batteries may be charged utilizing the charger.
