COMMENTS: The BR-3000 Battery Checker can only be used with the battery packs
            listed above. It cannot handle batteries of other cell sizes and
            types. The checker display is based on voltage. Since the voltage
            changes with the individual battery and the ambient temperature,
            use the remaining capacity display as a criteria only.
