How long can your energy storage Lifepo4 battery ‘live’?


Lithium iron phosphate batteries are widely used in the field of energy storage, but there are not many batteries that can really work stable for a long time.

The lifespan of lithium ion battery affect by many factors, including the physical characteristics of the battery cell, environmental temperature, and how it used. Among them, the physical characteristics of the batteries have the greatest effect on the lifespan of lithium ion batteries. If the physical characteristics of the battery cell do not meet the actual situation or the battery has a certain problem during use, it will affect the span life and practical functions of the battery.


1. Overcharging:

Excessive charging will cause the active material of the battery to be exhausted during the discharge process and fail. The span life decreases as the battery capacity gradually decreases.

2. Cell damage:

Lifepo4 battery will also be affected by the external environment in actual use. During the charging and discharging process, the battery cell is affected by the external voltage and temperature, which leads to damage to the internal structure and corrosion of internal materials. Therefore, scientific inspection and maintenance of battery cell is required. In addition, it is also necessary to pay attention to the impact of factors such as battery quality and safety issues on battery span life and function.

3. Insufficient lifespan of battery:

The low temperature of the monomer will shorten the lifespan of the battery cell. Changes in the structural parameters of the monomer will also cause internal resistance, volume changes, and voltage changes, which will affect the cycle life of the battery. Longer use time between battery cells and more cycles will also cause the internal resistance of the battery to become higher and reduce its energy density (this is due to short circuits inside the battery), resulting in a decrease in energy density.

4. If the temperature is too high or too low, it will also affect the lifespan of the battery.

Generally speaking, the temperature should be controlled between 25°C and 35°C, not exceeding 35°C


5. The poor performance of the battery cell results in a low lifespan, and the internal energy utilization rate of the battery cell is low.

The higher the content of nickel and cobalt elements in the positive electrode material, the more likely it is to form more oxides in the positive electrode; and the less likely it is to form oxides in the negative electrode. Due to this phenomenon, the positive electrode material has a large internal resistance and a fast volume expansion rate.

How long is the lifespan of Amensolar lifepo4 battery? The lifespan is different by different cell brand, we use the cell of international well-known brand, and refuse to offer insecure products to protect the quality of the batteries. And our batteries have a warranty of up to 10 years, which can dispel your worries about the battery span life. Our flagship product:A5120, this is a 2U thickness energy storage battery, a new design lifepo4 battery on 51.2V and 100AH, and it can reach a design life of 20 years at ambient temperature of 25°C. Another important information is the cycles life. The cycle life of the A5120 is over 6,000 times, which can meet the normal use of a family for more than 10 years.

For products with the same performance, we have also offered a wall-mounted lithium ion storage battery:AW5120. These two products are low-voltage batteries that is perfectly designed for 48V solar systems. One is rank mounted and the other is wall-mounted, meeting different needs. For A5120 and AW5120, we have done UL1973 and CE safety certification, and the professional certification certificate endorses our product testing, so that you can use it with more confidence.
