What is the difference between B grade and a grade batteries?
B grade cells have a higher rate of capacity fade as compared to A grade cells. Life – Lithium-ion cells are known for their long-lasting life. The cells degrade and their energy holding capacity reduces over time but they last for a long time, unlike Lead Acid batteries which experience sudden death.
What are the requirements for marking a battery?
6.3.1 The marking and cell designation (i.e. type of cell chemistry, discharge rate etc.) is to be in accordance with IEC 62620. Each cell or battery is to be clearly marked giving the following information: appropriate caution statement. 6.3.2 The model name and manufacturing traceability is to be marked on the cell and battery surface.
How do you know if a battery pack is B grade?
Another reason is the pressure from the OEMs to supply battery packs at an aggressive price. A technical way to know if the cell is B grade is to charge-discharge the cell for a suitable number of cycles depending on the cell capacity, chemistry, form factor and intended application of the battery pack and look at the data.
Why are lithium ion cells classified as B grade cells?
During the manufacturing of Lithium-ion cells, a very strict procedure is followed for grading them. Since no manufacturing process can produce 100% perfect yield, less than 10% of the produced cells do not meet the standards required to fall under A grade and hence they are classified as B grade cells.
What is a B grade cell?
B grade cells also have a minimum performance expectation and if they don’t meet it, they are further classified as C grade cells. C grade cells are the lowest priced cells in the market and they can be used for single-cell portable applications operating at a very slow charge and slow discharge rate with lower expected battery life.
