Which battery needs to be replaced?

1) If the actual discharge capacity of the battery is less than about 60% of the rated capacity, and the battery cannot be increased significantly after maintenance, it can be confirmed as being scrapped. This is because when the battery is in use, the function will be greatly attenuated after the capacity decays to about 60%, and all components have basically reached a deteriorating condition. This attenuation has a tendency to gradually accelerate, and the charge and discharge ability will soon be completely lost. 2) Whether the battery is charging or discharging, its shell is severely heated. The cause of heat generation is that the active material on the electrode plate falls severely, the internal resistance increases, and the heat generation increases. At this time, if you open the battery safety valve to check, you will see that the electrolyte is black, and it cannot be corrected when it is severely invalid. At this time, the battery self-discharges quickly, and sometimes it runs out soon after charging. 3) It will overflow after charging for less than 30 minutes, and it will be out of power after riding less than 1KM. A battery with an end of life has a significant decline in various functions and extremely unstable functions, which may cause undesirable consequences: such as heating and deformation, short-circuit or open circuit during charging, so when the battery reaches the end of its life, it should be replaced with a new battery in time. When choosing an electric vehicle battery, you must choose a high-quality, perfect after-sale brand battery.
