The battery short-circuit tester device, by setting carbon dioxide gas in the gas storage tank, can quickly extinguish the fire when the battery explodes and catches fire during the test, thereby reducing losses. After the fire is extinguished, the second handle on the turntable is turned to leak the ventilation slot, and then the fan is used to blow air into the test box, which can quickly reduce the temperature in the test box, making it convenient for staff to take the batteries in the test box, thereby improving safety performance.
