Calendar ageing tests of mixed cylindrical cells

Do you normally ride your bike at -20 °C in your country? Sorry, I couldn't help myself.

Sorry for both ot and answering a question that was not for me, but here you go:

It seldom is -20 here, but this was at -16c
The bike didn't complain, but I think it was damn cold and difficult to ride in the snow

For me it is an advantage if I could use regen at sub zero.

(funny thing is that BionX did not expect people to ride when very cold, too and they have been from Canada! WTF?! The temperature display does not know sub zero)

I should have realized that this question on the ES forum was completely pointless.

Great setup and data! Not to hijack the thread, but I am wondering if you have or have ever seen data for storing cells for multiple years? I have a need to store them for up to 5 years and know the capacity retained. I have not been able to find that data anywhere.

Just one year ageing data for capacity retention (self-discharge effect) at RT available. But I discovered a treasure in my refrigerator: cells from an older test from 2010. After the test was completed, the cells stayed in the freezer at -18°C for about next three years until today. I would like to publish the results on my Patreon channel in the near future.
