What is the actual lifespan of lithium iron phosphate battery packs? You must want to know. What is the true lifespan of a lithium iron phosphate battery pack? In fact, the lifespan of lithium battery packs is similar. Whether it is a lithium iron phosphate battery or a ternary lithium battery, the actual service life is related to the user's usage method and protection. As a backup power source for UPS batteries, lithium battery packs play a crucial role, and using the correct methods and regular maintenance can extend the service life and time of lithium iron phosphate battery packs. The editor of this article will talk about the actual lifespan of lithium iron phosphate battery packs.

What is a lithium iron phosphate battery?

Lithium iron phosphate battery is a type of lithium-ion battery that uses lithium iron phosphate as the positive electrode material. The characteristics are strong safety and stability, high temperature resistance, and good cycling performance.

What is the actual lifespan of lithium iron phosphate battery packs?

The cycle life of long-life lead-acid batteries is about 300 times, with a maximum of 500 times. Lithium iron phosphate power batteries have a cycle life of over 2000 times. A lead-acid battery of the same quality can last for six months, including new and old ones, and maintenance and upkeep, with a maximum lifespan of 1-1.5 years. However, a lithium iron phosphate battery pack, when used under the same conditions, has a theoretical lifespan of 7-8 years.

Lithium iron phosphate battery packs can generally be used for about 8 years; But if used in the south. The lifespan of lithium iron phosphate batteries is even longer than 8 years. The theoretical lifespan of lithium iron phosphate battery packs also exceeds 2000 charge and discharge cycles, and even if charged once a day, they can last for more than five years. Generally speaking, for daily household use, it can be recharged every three days and can also be used for about eight years. However, due to the poor low-temperature performance of lithium iron phosphate batteries, their lifespan will be relatively longer in southern regions.

The service life of lithium iron phosphate battery pack is about 5000 times, and each battery produced has its own cycle of discharge (such as 1000 times). If the number of charges and discharges exceeds this, the battery will die. Complete discharge will seriously affect the battery's use, so it is better not to discharge too much.

Which is the longer true lifespan between ternary lithium and lithium iron phosphate?

The ternary lithium battery material has 3900 cycles, with a remaining capacity of 66%. The lithium iron phosphate battery pack has 5000 cycles, with a remaining capacity of 84%. Its cycle life is significantly better than that of ternary material batteries and lithium iron phosphate batteries. Based on the remaining capacity/initial capacity=80% as the end point of the test, the 1C cycle life of the ternary material battery laboratory is currently around 2500 times, and the 1C cycle life of the lithium iron phosphate battery laboratory is over 3500 times, with some reaching over 5000 times. So, the actual service life of lithium iron phosphate batteries is longer and longer than that of ternary lithium batteries.

The lithium iron phosphate battery pack has stable output voltage, high output voltage, stable performance, large capacity, long service life, wide operating temperature range, good safety, and environmental protection without pollution. Therefore, it has great room for improvement in the future development of lithium batteries.

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

1. Large capacity. Lithium ion batteries can be made into single cells ranging from 5Ah to 1000Ah (1Ah=1000mAh), while lead-acid batteries typically have 2V single cells ranging from 100Ah to 150Ah, with a small variation range.

2. Lightweight. The volume of a lithium iron phosphate battery pack with the same capacity is two-thirds of the volume of a lead-acid battery, and the weight is one-third of the latter.

3. Strong fast charging ability. The starting current of the lithium iron phosphate battery pack can reach 2C, achieving high rate charging; The current requirement for lead-acid batteries is generally between 0.1C and 0.2C, which cannot achieve fast charging performance.

4. Environmental friendliness. Lead acid batteries contain a large amount of heavy metal - lead, which produces waste liquid, while lithium iron phosphate battery packs do not contain any heavy metals and are pollution-free in production and use.

5. High cost-effectiveness. Although lead-acid batteries have lower purchasing costs compared to lithium iron phosphate batteries due to their cheaper materials, they are less economical in terms of service life and daily maintenance compared to lithium iron phosphate batteries. The actual application results show that the cost-effectiveness of lithium iron phosphate batteries is more than four times that of lead-acid batteries.

That's all for the introduction of the relevant knowledge about the real life of lithium iron carbonate battery packs. Through the above introduction, I hope to bring some help to everyone. Lithium iron phosphate power battery, charged and discharged at room temperature of 1C, with a single cell capacity still greater than 80% after 2000 cycles, and a 3C cycle life of over 800 times, making it one of the longest batteries among all.
