FAQ: Different capacities of new Cells, with guaranteed minimum capacity according to Cell specifications.

Question: I make first initialization charging and I have already balanced cells.  After next discharging and charging some cells is discharged faster than others. I think that capacity of some cells is slightly less, so they cannot be balanced. Do I have to replace the cells?

Answer: Following the manufacturer guidelines: if one or more battery cells are faster or slower in charging, this does not mean they are defective.

The manufacturer guarantees a minimum capacity, but very often some of the cells may have more “Ah” than others, but always meet nominal capacity that is listed in the specification.

Example: for 500 Ah cells, if the battery capacity is above 500 Ah, then there is no reason of complaints. Rather, it is great to have a capacity over 500 Ah.

Note: The positive tolerance of  the LiFePO4 cell capacity is not a cause for complaints.
