Maintenance methods

　　1. Do not store without electricity. Low battery state refers to the failure to charge the battery in a timely manner after use. When the battery is low, it is prone to sulfation, and lead sulfate crystals attach to the electrode plate, blocking the ion channel, causing insufficient charging and a decrease in battery capacity. The longer the idle time in a low power state, the more severe the battery damage. When the battery is idle and not in use, it should be charged once a month to extend its service life.

　　2. Regular inspections are required. During use, if the range of an electric bicycle suddenly drops by more than ten kilometers in a short period of time, it is highly likely that at least one battery in the battery pack has a short circuit phenomenon such as broken grid, softened electrode plate, or detachment of active substances from the electrode plate. At this point, it is necessary to promptly go to a professional battery repair agency for inspection, repair, or assembly.

　　3. Do not discharge with high current. When starting, carrying people, or climbing an electric bicycle, it is best to use pedals to assist and try to avoid sudden high current discharge. High current discharge can easily lead to the crystallization of lead sulfate, thereby damaging the physical properties of the battery plate.

　　4. Master the charging time. Generally, batteries are charged at night, with an average charging time of around 8 hours. If there is a shallow discharge (with a short driving distance after charging), the battery will quickly become fully charged, and further charging will lead to overcharging, causing the battery to lose water and heat, reducing its lifespan. Therefore, it is best to charge the battery once when the discharge depth is 60% -70%. In actual use, it can be converted into cycling mileage, and necessary charging should be carried out according to the actual situation to avoid harmful charging.

　　5. Prevent high temperature exposure. Electric vehicles are strictly prohibited from being exposed to sunlight. An excessively high temperature environment can increase the internal pressure of the battery, forcing the battery pressure limiting valve to automatically open. The direct consequence is an increase in the water loss of the battery. Excessive water loss of the battery will inevitably lead to a decrease in battery activity, accelerate the softening of the electrode plate, and cause fatal damage such as shell heating, bulging, and deformation during charging.
