How long is the real life of lithium iron phosphate battery ?
- 2025-06-09 15:51 -


       The actual life of lithium iron phosphate batteries is affected by many factors, including usage conditions, charge and discharge frequency, charging method and ambient temperature. In general, the life of lithium iron phosphate batteries is longer than that of ternary lithium batteries, as follows:


Cycle life: The cycle life of lithium iron phosphate batteries is generally more than 2,000 times. Theoretically, it will begin to decay after 3,500 charge and discharge cycles. CSiT's high-quality lithium iron phosphate Battery Cells can be deeply cycled up to 5,000 times, and the theoretical service life can reach 10 years.


Battery degradation: Under ideal conditions, the capacity degradation of lithium iron phosphate batteries usually does not exceed 5% in the first year of use, and may decay to about 15% in the second year. In contrast, the degradation rate of ternary lithium batteries is faster, and there may be a significant capacity drop within a year.


Application scenarios: Lithium iron phosphate batteries are suitable for areas that require long life and high safety, especially electric vehicles and large Energy Storage systems. It is common for electric vehicles to use lithium iron phosphate batteries. Under normal conditions, the battery can support a service life of about 15 years, and if charged once a day, it can theoretically still be used for more than five years.


Charging habits and maintenance: The actual life of the battery is also related to the charging frequency and maintenance. Reasonable charging methods can extend the battery life, while frequent overcharging or high temperature environment may accelerate the decline.


Environmental impact: Low temperature environment may affect the performance of lithium iron phosphate batteries, especially in cold northern regions, where the low temperature performance of the battery is poor. However, in warm regions such as the south, the battery life is relatively long.

In general, lithium iron phosphate batteries have obvious advantages over other types of lithium batteries (such as ternary lithium batteries) in terms of cycle life and stability, and are therefore more suitable for long-term and stable use.  If you would like more information or have any questions, please contact us for more information info@ptpbattery.com.
