This is one of the older Samsung cells, the datasheet is marked 2010. With 10A rated current it was a high current cell.










The cell has fairly constant capacity at any load, but there is a small difference in internal resistance.















Conclusion

The cell looks good, but today there are better performing cells on the market.
