The curves tracks perfectly. The battery is only rated for 10A, but works fine at 20A with very little capacity loss.

Due to the very short discharge time I do not really see much heating.

Conclusion
This battery can deliver very impressive currents, but compared to modern batteries the capacity is way too low.

Vapcell told me that I was missing some cells in my comparator and they would be happy to supply them.

Thanks, as always, for doing such work to produce such thorough reviews for us! I do think it’s a bit silly of Vapcell to care about this cell. But, it doesn’t hurt having the info available in the comparator, since someone may still own and use these cells, I guess.

I do not know it Vapcell is selling this cell or just have access to it, but they have supplied me with lot of older cells. I like getting more cells in the comparator, even old cell.
