The capacity is not only depend on load, but also depend on the minimum voltage that is needed.

The 0.1A trace did take about 7 days to do, but it did give more energy than a 3 days discharge.

Conclusion

These batteries works best at low loads, but you can get about half the energy out of them at 1A load.
I do prefer NiMH or LiIon batteries, they can deliver considerable more power without loosing half the energy.
