What is the cycle number and real life of lithium iron phosphate battery pack?

What is the real life of lithium iron phosphate? In fact, the life of a lithium battery pack is nearly the same, whether it is lithium iron phosphate battery or ternary lithium battery, the real service life is related to the user's method and protection. In this article, let's talk about what is the real life of lithium iron phosphate battery pack.

What is lithium iron phosphate battery?

Lithium iron phosphate battery is one kind of lithium ion battery, which refers to lithium ion batteries that use lithium iron phosphate as the cathode material. Its characteristics are with strong safety and stability, high temperature resistance and good cycling performance.

What is the real life of lithium iron battery pack?

Long-life lead-acid batteries have a cycle life of around 300 cycles, up to 500 cycles at most while the lithium iron phosphate battery has a cycle life of more than 2000 cycles. The same quality of lead-acid battery is "new for half year, old for half year, maintenance for another half year", up to 1 to 1.5 years, but the theoretical life of lithium iron phosphate battery pack will reach 7~8 years under the same conditions.

Lithium iron battery pack is generally used for about 8 years, and its life will be a little longer than 8 years in south regions. The theoretical life of lithium iron phosphate battery pack is also more than 2000 cycles of charging and discharging, it can last for more than 5 years even if it is charged once a day. Generally speaking, daily household for three days a charge, can also be used for about 8 years. However, due to the poor low temperature performance of lithium iron phosphate battery, the life of lithium iron phosphate will be relatively longer in the south regions.

The service life of lithium iron battery pack is about 5000 cycles, the battery has its own cycle discharge times (such as 1000 times) after produced, the battery life will end after more than this number, complete discharge will seriously affect the use of the battery, so don't keep it over discharging.

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

1. With high capacity. Monoblock lithium battery can be made as 5Ah~1000Ah (1Ah=1000mAh) while the monoblock 2V lead-acid battery is usually 100Ah~150Ah, the change interval is small.

2. With light weight. A lithium iron phosphate battery pack of the same capacity is two thirds the volume and one third the weight of a lead-acid battery.

3. With strong ability of quick charge. The start current of lithium phosphate battery pack can reach 2C, achieve high power charging. The current of lead-acid batteries is generally required to be between 0.1C and 0.2C, so it cannot reach quick charging performance.

4. Environmental friendly. Lead-acid battery contains a large amount of heavy metal-lead, resulting in waste liquid, while lithium iron phosphate battery pack does not contain any heavy metal, which is pollution-free during producing and using.

5. With high cost performance. Although the purchase cost of lead-acid battery is lower than that of lithium iron phosphate battery due to its cheap material, it is less economical than lithium iron phosphate battery in service life and daily maintenance. The pratical application results show that the cost performance of lithium iron phosphate battery is over 4 times more than that of lead-acid battery.
