I was wondering how well Li-Ion 18650s will hold their charge?



Alkalines seem to hold charge well, even partially used ones (given that care should be taken to avoid corrosion and leakage).



Ni-Mh seem to lose charge quite quickly on the shelf, unless they're Eneloops or similar.



But if I charge up my Li-ion 18650, how long will it remain 'fresh'? Do they have good 'shelf life'..?? And if not, are they happy with top up charging?
