How to determine the lifespan of lithium batteries
Judging the lifespan of lithium batteries can help us replace them in a timely manner, ensuring the normal operation and safe use of equipment. Here are several methods to determine the lifespan of lithium batteries:
1. Number of charge and discharge cycles : The lifespan of lithium batteries is usually measured by the number of charge and discharge cycles. The charging and discharging cycles of most lithium batteries are around 500 times. When the charging and discharging cycles of the battery approach or exceed this value, the performance of the battery may significantly decrease.
2. Battery Capacity : As the usage time increases, the capacity of lithium batteries will gradually decline. The actual capacity of the battery can be detected through equipment or specialized tools. If the actual capacity is significantly lower than the nominal capacity, it indicates that the battery's lifespan is approaching its end.
3. Equipment Performance : When the lifespan of a lithium battery approaches its end, the performance of the equipment may be affected. For example, frequent automatic shutdown of mobile phones or laptops during normal use, or severe heating during charging, are signs of decreased battery life.
4. Battery Appearance : Check the appearance of the battery. If abnormal phenomena such as bulging, deformation, and leakage are found on the surface of the battery, it indicates that the internal structure of the battery has been damaged and the battery's life may have ended.
5. Charging time : When the lifespan of a lithium battery approaches its end, the charging time of the battery may be significantly prolonged, or the battery temperature may abnormally rise during the charging process, all of which are manifestations of a decrease in battery lifespan.
6. Device Reminder : Some devices have a battery health status prompt function, which can be viewed through the device's system information or dedicated software to check the battery's health status
