The grades of Lifepo4 cells are an indicator of their quality, and the information is generally required when you are searching for a battery. They are evaluated by three essential criteria – energy density, discharge voltage, and cycle life.
The higher energy and density contain, the better performance of the battery. The higher discharge voltage indicates that the power is more significant than, the lower voltage. Therefore, it is more suitable for high-power loads. In addition, it has excellent cyclic properties and can maintain over 90% of capacity after 1000 cycles. It is essential to understand the difference between the two grades of Lifepo4 cells. It will ensure you use the correct battery for your application and provide you with the expected output.
Apart from the battery’s discharge test performance, it will also be classified according to its capacity. It can fruitfully be divided into two categories: A and B. In this article, you will find the grades of Lifepo4 cells. It’ll explain how they differ, why they’re essential, and which quality suits you best.
What Is Grade A LiFePo4 Cell?
LiFePo4 grade A cells are lithium-iron-phosphate battery cells that meet the battery’s quality standard. These battery cells don’t cause swelling or abnormal chemical reactions within them. The result is a fully functional battery with a long lifespan.Grade A cells can be relied on for their superior performance and longevity. They have passed strict quality control procedures, ensuring the most consistent cell chemistry and electrical performance.
What Is Grade B Lifepo4 Cell?
LiFePo4 grade B cells are made from the same raw material as LiFePo4 grade A cells, with strict quality control procedures. Grade B cells have not been used yet, and some may have defects.When the defective rate of a cell increases, it can cause instability which impacts everything from charging to discharging. Beyond this, LiFePo4 grade B cells have different power consumption patterns than grade A.It depends on the type of circuit being used. Grade B cell has energy storage, and charge/discharge capabilities are similar to the grade A cell.
What Reasons Occurs That Changes Cells From A Grade To B Grade?
In factories, any production process is bound to have some percentage of products that fails. It determines how much a factory can produce. In the lithium battery industry, the quality levels are not easily distinguishable from one end of the line to another.It’s important to note that small-scale manufacturers don’t have machines that can solve the problems of their larger counterparts. Their defect rate is still reasonably high because of a lack of size and resources.The average LiFePo4 grade B battery lasts the same time and performs the same quality. You have to pay more for a LiFePo4 grade A because it lasts significantly longer than grade B.If a grade A cell is put in a warehouse for 3-6 months, it becomes grade B. It is why a grade B battery is created and has problems. This guideline cannot be relied on, but if the battery goes wrong, then it’s worth replacing.
