A hybrid batter is provided to enable stable charge/discharge of batteries having different capacities, to allow charge/discharge of cells using power of the batteries alone, to increase the charge/discharge efficiency by using a current interrupt device and a protection device. A hybrid battery comprises: a plurality of rechargeable batteries(111,112); a switching part(120) electrically connected to high current paths of the batteries to select any one of the high current paths of the batteries for electric connection; and a hybrid battery protection circuit part(130) electrically connected to the batteries, driven by receiving electric power from any one battery, and electrically connected to the switching part to send on/off signals to the switching part so that the batteries are sequentially charged/discharged. |
