Abstract: A battery loading mechanism requires that a battery is inserted with a positive electrode terminal inserted first into a battery chamber. The battery chamber is formed with a space into which the battery is inserted from an insertion port opened outside. A positive-side electrical contact is provided in an inner part, opposite to the insertion port, of the battery chamber, and a negative-side electrical contact is provided on a side of the insertion port of the battery chamber.

More particularly, a multi-cell secondary battery includes multiple secondary battery cells connected in parallel and a unidirectional current valve connected in series with at least one of the secondary battery cells. The unidirectional current valve may be a diode, for example. Switching circuitry is connected in parallel with the unidirectional current valve to allow for recharging by bypassing the unidirectional current valve.
