The configuration of the present invention includes a battery-body posited in a case, a communication circuit whose output lead connects to said battery-body and charges it, an alternator, a vibration installation whose output lead connects to a rotor of the alternator. Alternatively, a direct current dynamo is posited in the case, the output lead of the vibration installation connects to a rotor of the direct current dynamo. The battery of the present invention can be charging without charger and external power. So use of this battery avoids burden of taking charger and life of the battery is long.</p> |
