As electric vehicles become increasingly popular, the service life and replacement cycle of 18650 lithium batteries,
as the core power source of electric vehicles, have become the focus of attention of the majority of electric vehicle
users. So, how often do 18650 batteries in electric vehicles need to be replaced?
The life of 18650 lithium batteries is affected by many factors, including battery quality, usage habits, charging methods,
and environmental conditions. Generally speaking, high-quality 18650 lithium batteries can have a cycle life of
500-1000 charge and discharge cycles under normal use and proper maintenance. This means that if a complete
charge and discharge cycle is performed every day, the theoretical service life of the battery may be around 1-2 years.
However, the actual service life may vary depending on personal usage habits and environmental conditions.
In order to extend the service life of 18650 lithium batteries, users should pay attention to the following points:
First, avoid the battery being in a high or low temperature environment for a long time to avoid damage to the
battery performance; second, try to use the original charger for charging, and avoid using an unmatched or inferior
charger to cause the battery to be overcharged or over-discharged; finally, check the battery status regularly. If
abnormal conditions such as battery bulging or leakage are found, they should be replaced in time.
When the 18650 battery of an electric vehicle shows a significant decrease in mileage, prolonged charging time,
or unstable battery performance, it may be a signal that the battery life is about to end. At this time, users should
consider replacing the battery to ensure the normal use and driving safety of the electric vehicle.
In short, the replacement cycle of the 18650 battery of an electric vehicle is affected by many factors, and users
should make judgments and decisions based on actual conditions. Through proper use and maintenance, the
battery life can be extended, the replacement cost can be reduced, and efforts can be made to contribute to
environmentally friendly travel.
