Rechargeable battery pack interchangeable with ordinary commercial batteries, has a battery safety unit, at least two individual batteries that have a cathode and an anode and a circuit board that contains a battery safety unit designed to shut off the electric current to the battery cell when the current has been over-charged in the recharge electrode and to stoop the discharge of the battery pack when the output voltage of the discharge electrode falls below a certain voltage. A cathode connecting conductor connects the recharge and discharge electrodes to the cathode terminals of the individual batteries, and an anode connecting conductor connects the recharge and discharge electrodes to the anode terminals of the individual batteries. A cover contains the circuit board and ties the individual batteries, the cathode connecting conductor, the anode connecting conductor and the circuit board as a single battery pack format in the individual battery's upper and lower bodies. At least one of the cathode connecting conductor and the anode connecting conductor is electrically connected to the circuit board. The battery pack of this invention can be, for example, made of lithium ion battery and used in portable electronic devices such as a digital camera. |
