These batteries are supposed use the same cell as the button top, but they do not. This cell has more capacity.

There is good matching between the two cells and the capacity is fairly stable with load.
Sorry about the missing 0.2A trace, I made a mistake in the test setup. Because all the other tracks has a good match, I see no reason to make the missing trace.

Conclusion

They have a good performance, but cannot match some moderen high current cells.
I will rate them as acceptable.
