Why can't the battery/battery pack discharge electricity?

What happens when the battery/battery pack cannot be discharged? Phenomenon: After charging, it is installed in the device, the device cannot work, the open circuit voltage of the battery pack does not change or changes little 1) Check whether the battery/battery pack is a zero voltage, high internal resistance battery; 2) The battery pack is connected to electronic components , Whether the protection circuit is damaged; 3) Check whether the discharge circuit of the equipment is normal. Solution: 1) Use a battery/battery pack of the same type that is overflowing to connect to the device, and whether the device is working properly; 2) Use a multimeter to test whether the internal electronic components and protection circuit of the battery are normal. 3) Repeat the zero-voltage steps of the single battery to decompose and solve; 4) If the discharge circuit of the electrical appliance is abnormal, it is recommended that the customer repair and replace the electrical appliance in time; 5) If the customer does not modify the battery pack by itself, a dedicated technician is required. Further decomposition. Disclaimer: Some pictures and content of articles published on this site are from the Internet, please contact to delete if there is any infringement.
