The invention discloses a detecting system for detecting whether a battery is connected to an electronic apparatus. The battery has a thermic resistor. The detecting system includes a power supply, a detecting resistor, and a detecting unit. The power supply generates a testing current. The detecting resistor is connected to the power supply and the thermic resistor. The detecting circuit is connected to a node between the detecting resistor and the thermic resistor. The detecting circuit detects a first voltage of the node and generates a detecting signal to determine whether the battery is electrically connected to the electronic apparatus.
