Provided are battery for mobile electronic device with waterproof function and method thereof. The battery includes a battery cell, an internal terminal that electrically connects the battery cell and the mobile electronic device, and a discharge circuit that electrically connects the internal terminal and the battery cell when the battery is combined with the mobile electronic device and electrically disconnects the internal terminal from the battery cell when the battery is separated from the mobile electronic device. The discharge circuit includes a hole sensor that senses a magnetic field generated by a magnet included in the mobile electronic device, and a switching circuit that electrically connects the internal terminal and the battery cell when the hole sensor senses the magnetic field. Accordingly, when the battery is not combined with a main body of the mobile electronic device or contacts water, a discharge path from the battery to the main body is blocked, thereby protecting the battery and the internal circuit of the main body. |
