What happens if the lithium battery pack does not discharge? The lithium battery pack does not discharge phenomenon: After charging the lithium battery pack enters the device, the device cannot work, and the open circuit voltage of the battery pack does not change or changes little. 1) Check whether the voltage of the battery/battery pack is zero and whether the internal resistance is high; 2) The electronic components and protection circuits connected in the battery pack are not damaged; 3) Check whether the discharge circuit of the equipment is normal. 4) Whether the tabs are broken into an open circuit and the lithium battery has no discharge treatment: 1) The equipment is connected to the same type of charged battery/battery pack, and whether the equipment is working normally; 2) Check whether the internal electronic components and protection circuit of the battery are normal with a multimeter. 3) Repeat the single battery zero-voltage step analysis and processing; 4) When the electrical discharge circuit is abnormal, it is recommended that the user repair and replace it in time; 5) If the customer does not replace the battery by himself, a dedicated technician is required for further analysis.
