Yeah well it’s been two weeks or so and they’re doing great! 
That’s the thing with these small cells, you usually keep these fully charged because of EDC carry etc and they do degrade.
I do recommend putting cells through discharge/ recharge cycles every month or so, even if you don’t usually use the cell much but like to keep it fully charged, no scientific evidence for this, just a hunch 
I still have one or two original DQG & Valeno designs 10180s from around 4-5 years ago and they measure around 35-45mAh capacity now. Still not bad but every bit of capacity helps in these tiny cells.
I just buy new cells every couple years as I EDC three 10180 compatible lights.
