The life of lithium iron phosphate batteries is affected by a variety of factors, including the physical characteristics of the cell, ambient temperature, and how to use it. The following is a detailed explanation of the life of lithium iron phosphate batteries:
Physical properties of the battery:
The physical properties of the battery cell have the greatest impact on the actual life of the lithium-ion battery. In the case of better quality, the attenuation of lithium iron phosphate batteries can be controlled at a low level. For example, the attenuation can be controlled within 5% in the first year and 15% in the second year.
Cycle life:
Lithium iron phosphate batteries usually have a very long cycle life. The single battery can reach more than 5000 times under 100% deep cycle, and the theoretical service life can reach 10 years. This means that in an ideal state, it can last for more than five years, even if it is charged once a day.
Ambient temperature:
Lithium iron phosphate batteries are greatly affected by temperature. In a low temperature environment, the discharge capacity and average discharge voltage will be reduced. Working and charging and discharging in a low temperature environment for a long time can cause permanent damage to the battery capacity. In the south and other warmer climate areas, the life of lithium iron phosphate batteries will be relatively long.
How to use:
The way a battery is charged and discharged can also affect its lifespan. For example, overcharging can cause the active material of the battery cell to be depleted during the discharge process and fail, shortening the battery life. Therefore, the charging depth should be controlled during use to avoid overcharging.
To sum up, the life of lithium iron phosphate batteries is usually about 8 years, but the specific life depends on various factors such as the physical characteristics of the cell, the ambient temperature and the method of use. Under ideal conditions, its theoretical service life can reach more than 10 years. However, in practical applications, its actual life may be shortened due to various factors. Therefore, in order to prolong the life of lithium iron phosphate batteries, attention should be paid to controlling the charging depth, avoiding overcharging and discharging, and using them at appropriate ambient temperatures.
