发明名称 Page power conversion apparatus for battery charging
摘要 Compact conversion apparatus fits within a small space in a densely-constructed, battery-powered pager to convert the unit from use only with non-rechargeable replacement batteries to operation with a rechargeable battery. Notwithstanding space limitations, the conversion apparatus leaves the battery secure against an accidental short circuit at the newly-added, externally-accessible power input.
