How Many Years Can a Ternary Lithium Battery Last?
2 Answers
The service life of a ternary lithium battery can reach around 10 years. Methods to extend the battery's lifespan are as follows: Pay attention to the temperature of the usage environment: Do not use the battery in environments where the temperature exceeds 60 degrees Celsius. When the temperature drops below minus 5 degrees Celsius, stop charging the battery pack or the vehicle. Long-term storage requires safe power-off: If the battery will not be used for an extended period, it is recommended to disconnect the maintenance switch of the power battery. This will internally disconnect the power battery, preventing power loss and ensuring the battery's safety. Avoid overcharging and over-discharging the battery: Charging the battery daily can enhance its activity, whereas frequently waiting until it is completely drained before charging will reduce its lifespan.
As a long-time electric vehicle user with high driving frequency, I can confirm that ternary lithium batteries typically last between 8 to 10 years or over 150,000 kilometers. From my practical experience, battery longevity largely depends on daily maintenance: avoid consistently charging to 100% or discharging to 0%. Maintaining a charging range between 20% to 80% is ideal to minimize deep-cycle degradation. Parking under direct sunlight during hot weather accelerates battery aging, while prolonged inactivity in winter can reduce performance due to low temperatures—pre-warming the battery before use is advisable. Driving habits also significantly impact battery life—smooth driving without frequent hard acceleration or braking helps preserve the battery. Regular check-ups at authorized service centers, such as using diagnostic tools to monitor remaining capacity, ensure early detection of potential issues. With proper care, these batteries can reliably last a full decade without failure.
