Abstract:
1. A battery charger comprising: a battery pocket in a case for mounting AA batteries and AAA batteries in manner allowing loading and unloading, temperature detection sections to contact and detect the temperature of AA batteries and AAA batteries loaded in the battery pocket, and a charging circuit to detect battery temperature via the temperature detection sections and control battery charging; AA battery holders are provided to retain AA batteries in fixed positions in the battery pocket, AAA battery holders are provided to retain AAA batteries in fixed positions in the battery pocket, AA battery holders are circular openings in the case, and AAA battery holders are flexible arches; wherein a circular opening is an opening in the case with a size that can accept and hold an AA battery in a fixed position, a flexible arch is an arch-shaped arm in which an AAA battery can be inserted but an AA battery cannot be inserted, and it is attached in a manner allowing it to flexibly incline when pressed against by an AA battery; an AAA battery is inserted into a flexible arch holder and retained in a fixed position in the battery pocket, an AA battery is not inserted into a flexible arch, but rather moves the flexible arch causing it to incline, and is inserted into a circular opening holder for retention in a fixed position in the battery pocket; and batteries set in fixed positions in the battery pocket are charged while detecting battery temperature via the temperature detection sections.
