Because the storage battery is in a floating charge standby state at ordinary times, the performance of the storage battery is degraded after a long time, and the running reliability of a direct-current power supply system is reduced, the storage battery is necessary to be periodically detected, maintained or replaced.

At present, a direct current power supply is generally disconnected for replacing failed batteries in China, a standby battery is placed on a charger and then quits from a battery to be replaced, the replacement speed is greatly reduced, the running safety of a direct current system is affected, time and labor are wasted, a bridging device is adopted in the prior art to detect the quality of the battery, the detection efficiency of the traditional method is greatly improved, but after the battery is used for a long time, labels at the positive electrode and the negative electrode are worn and disappear, so that the positive electrode and the negative electrode are difficult to distinguish, and more time is consumed for replacing the battery. In the traditional method for directly detecting the voltage through the bridging device, after the end clamp is connected with the battery, whether the resistance value of the voltmeter exists or not is judged, so that the battery detection is inconvenient, and the detection efficiency is delayed.

Therefore, in order to solve the above-mentioned problems, a battery jumper device for battery replacement has been proposed.
