In a charge device having a storage cell terminal for connection to a storage cell to be charged, a trickle charge terminal for receiving a trickle charge voltage, and a boost charge terminal connected to the storage cell terminal for receiving a boost charge voltage and including a constant current circuit for causing a constant current to flow from the trickle charge terminal to the storage cell terminal, a boost charge detector detects the boost charge voltage to produce a boost charge signal when the boost charge terminal is supplied with the boost charge voltage. An interrupting circuit interrupts the constant current when the boost charge detector circuit produces the boost charge signal. The constant current circuit may comprise a transistor having a base electrode supplied with the trickle charge voltage to produce the constant current. In this event, the interrupting circuit is a conductor connected between the boost charge detector and the base electrode of the transistor.
