ABSTRACT:
A battery device for use as a power source for portable electric or electronic appliances. The battery device includes a case (28) which defines a closed space and which is made of hardly flammable and shock-resistant synthetic resin, and secondary batteries (35, 37) and a breaker (45) are disposed in the case. The breaker is connected to the electrodes of the secondary batteries and placed in a charge-discharge circuit including electrically conductive lines and detects the current in the charge-discharge circuit and the environmental temperature in the case, the arrangement being such that when the current or the environmental temperature exceeds a predetermined value, it cuts off the charge-discharge circuit and when the current or the environmental temperature falls below the predetermined value, it is automatically restored to its original state.
