This is a full capacity C cell from Germany (It is made in China and bought in Denmark).
Maximum temperature raise at different discharge currents: 1A:+0,4°C, 2A:+2,8°C, 3A:+4,6°C, 5A:+8,5°C, 7A:+11,6°C, 10A:+15,9°C, 15A:+20,9°C









Very well matching discharge curves and the cell easily match the rated capacity.















Conclusion

This looks to be a very good quality C sized NiMH battery with lots of capacity and low self discharge.
