How many years is the real life of a lithium iron phosphate battery pack?

The life of a lithium battery pack is about the same, whether it is lithium iron phosphate or a ternary lithium battery, the actual life is related to the user's use and protection. This article will talk about the real life of lithium iron phosphate battery packs how long?


What is LiFePO4?

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


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

Long-life lead-acid batteries have a cycle life of about 300 times, and up to 500 times. Lithium iron phosphate power batteries have a cycle life of more than 2000 times.

The same quality of lead-acid batteries is "new half year, old half year, maintenance and a half year", at most 1 to 1.5 years, while lithium iron phosphate batteries set in the same conditions of use, the theoretical life will reach 7 to 8 years.

Lithium iron phosphate battery pack is generally used for about 8 years is possible; but if used in the south. Lithium iron phosphate battery life is also a little longer than 8 years. Lithium iron phosphate battery packs theoretical life of the same more than 2000 charge and discharge cycles, even if a day a charge, can also be maintained for more than five years.

Generally speaking, the daily household for three days charge, can also be used for about eight years. However, due to the poor performance of lithium iron phosphate at low temperatures, in the southern region, the life of lithium iron phosphate will be relatively longer.

Lithium iron phosphate battery pack life is about 5000 times, and the battery produced have its cycle discharge times (such as a thousand times), more than this number of charge and discharge, the battery will die, and complete discharge will seriously affect the use of the battery, so do not over-discharge on it.

Advantages of LiFePO4 battery pack compared with a lead-acid battery.

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 a small variation range.

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

3. Fast charging capability.
Lithium iron phosphate battery pack start current up to 2C, to achieve large multiplier charging; lead-acid battery current is generally required between 0.1C ~ 0.2C, and can not reach fast charging performance.

4. Environmental protection.
Lead-acid batteries exist in large quantities of heavy metals - lead, producing waste liquid, while lithium iron phosphate battery pack does not contain any heavy metals, in the production and use are pollution-free.

5. High-cost performance.
Although lead-acid batteries because of its cheap materials, the acquisition cost is lower than lithium-iron phosphate batteries, and the service life and routine maintenance of the economy are lower than lithium-iron phosphate batteries. Practical application results show that: lithium iron phosphate batteries are more than four times the cost performance of lead-acid batteries.
