Have you found the cell database to be helpful as you collect packs/cells and work on your project?
Jon said:Very helpful
Im selecting cells using tested capacity as a percentage of original capacity as well as tested capacity.
To me if two cells test at 1900mAh and ones original capacity was 2200mAh and the other 2800mAh the one with the higher percentage of original likely has more life left.
Im sorting into 100mAh buckets and then ranking as percentage of original capacity.
Must admit if a cell is xx9xmAh it gets pushed into the bucket up :0

This is largely true. However the original specs give a good idea of how 'worn' the cell is. If a cell is a lot less (like 50%) than its original capacity, I tend to set them aside. They usually have issues with self discharge.
