My charge curve do not look that good, the B cell is terminated a bit early, that can also be seen on the 2A discharge curve, the B cells has slightly less capacity.
Conclusion
There are not many 10440 cell on the market and this is one of the better. The capacity is in top, but the voltage is a bit low.

Could it be that 500mA charge current is too much for these cells? It’s almost 1.5C. They are rated for 350mA max.
Cell A looks strange in the CV phase, like it’s “recovering”.
Also the voltage curve of B after termination is unusual.

The charger current is too high and it might be the reason, but I am not sure about it.
I do not generate curves of the temperature during charge, they might have been useful here.

For what seems to be a tiny cell with slightly above 320ish mΩ of effective internal resistance, looks nice.

I'd say this is the workhorse of its category. The show at 1A is a very bit lacking, but of course this is no high discharge cell.

Nice price.

 

The human mind, and its programming, is at the forefront of a particular battle of The Light vs evil dark forces. Nearly every human being on this beautiful planet “Earth” has some sort of negative mind programming in its mind. And you better take care of your mind programming, or someone else will in this wicked world.

Thanks for the review HKJ!

I have a few pairs of these. They are cheap and work well. Charging is a pain on small cells. On most chargers the lowest setting is still to high lol. I guess around 150-200mah would be a good charging current for these cells.

I like them they go well with lots of lights. When i got these Soshine was a big battery player now i dont really see them much. I also have some Soshine AA NiMH they are okay. I have a Soshine lithium charger from 2012 also when they where highly recommended.

(This is what it feels like to get older i wrote all that for no reason at all. It has nothing to do with this lol)
