How long is the real life of lithium iron phosphate battery pack? In fact, the service life of lithium battery pack is almost the same. Whether it is lithium iron phosphate battery or ternary lithium battery, the actual service life is related to the user's use method and protection. How long is the real life of lithium iron phosphate battery pack?

 

 

 

What is lithium iron phosphate battery?

 

 

 

Lithium iron phosphate battery is a kind of lithium ion battery, which uses lithium iron phosphate as cathode material. It is characterized by strong safety and stability, high temperature resistance and good cycling performance.

 

 

 

How long is the real life of lithium iron phosphate battery pack?

 

 

 

The cycle life of long-life lead-acid battery is about 300 times, and the maximum cycle life is 500 times. Lithium iron phosphate power battery, with a cycle life of more than 2000 times. The lead-acid battery of the same quality is "new half year, old half year, and maintenance half year", which is only 1~1.5 years at most. The theoretical life of lithium iron phosphate battery pack will reach 7~8 years when it is used under the same conditions.

 

 

 

The lithium iron phosphate battery pack can be used for about 8 years generally; But if it is used in the south. The life of lithium iron phosphate battery is longer than 8 years. The theoretical life of lithium iron phosphate battery pack also exceeds 2000 charging and discharging cycles. Even if it is charged once a day, it can last for more than five years. Generally speaking, the daily household charge is three days, and it can last about eight years. However, due to the poor low-temperature performance of lithium iron phosphate battery, the service life of lithium iron phosphate battery will be relatively longer in the southern region.

 

 

 

The service life of lithium iron phosphate battery pack is about 5000 times. The battery has its own cycle discharge times (for example, 1000 times). If the battery is charged and discharged more than this time, the battery will die. Complete discharge will seriously affect the use of the battery, so don't over discharge.

 

 

 

Advantages of lithium iron phosphate battery pack compared with lead-acid battery pack:

 

 

 

1. Large capacity. Lithium battery monomer can be made into 5Ah~1000Ah (1Ah=1000mAh), while lead acid battery 2V monomer is usually 100Ah~150Ah, with small variation range.

 

 

 

2. Light weight. The volume of lithium iron phosphate battery pack with the same capacity is 2/3 of the volume of lead-acid battery, and the weight is 1/3 of the latter.

 

 

 

3. Strong fast charging capacity. The starting current of lithium iron phosphate battery pack can reach 2C, realizing high rate charging; The current of lead-acid battery is generally required to be between 0.1C and 0.2C, which cannot achieve fast charging performance.

 

 

 

4. Environmental protection. Lead acid battery contains a large amount of heavy metal lead, which generates waste liquid. However, lithium iron phosphate battery pack does not contain any heavy metal, which is pollution-free in production and use.

 

 

 

5. High cost performance. Although the lead-acid battery is cheaper than the lithium iron phosphate battery due to its cheap materials, it is less economical than the lithium iron phosphate battery in terms of service life and daily maintenance. The practical application results show that the cost performance ratio of lithium iron phosphate battery is more than 4 times that of lead-acid battery.
