A high current cell, but the specifications looks a bit dated.











The discharge curves look very good with both fine tracking and constant capacity at different load up to 10A.















Conclusion

Being a Sony it is a very good cell and a few years ago this would have been a well performing high current cell, but today there are many cells with better performance.
