Calender ageing is *extremely* slow when the battery is at storage voltage (about 30-40% charged aka 3.8-3.9 volts). I would not expect more than 1-2% reduction in capacity from original and given that the original capacity is already about 5-10% higher than rated capacity, it is still effectively a perfectly health cell. *as long as* it has not been stored at elevated temperatures. Calender aging is a function of temperature and state-of-charge. At 20°C and 40% Soc, a Li-NCM battery will last a decade or more before reaching its 80% "end of life" capacity
I use "always on display" and get 2 or 3 days EASILY depending what watch face i use. Been a good watch
Yeah that´s why i want them instead of 6 Classic im just worried that they are 9 months old since manufacturing and the battery would be bit broken
Good point, I hope someone else can weigh in on this. I'd be interested in finding out.

So they came fully discharged, but took usual time to charge and so far everything looks fine
