I am not one to try to get 3 years of use out of a cheap (low cost) cell. I like a 95-100% full charge each and every time I charge a cell. I don't want to have to
roll,
pull and reinsert or
reset in order to get the charge I want.
Whenever you or I put two cells in a two-bay charger, we should get, on completion, two fully (or close) charged cells with
matching voltages. Not one cell having 4.20v and the other with 4.12 or 4.16v. When this happens, you have to perform one of the above actions to get the voltage up to match the other cell. Good luck with that. It is a nuisance, a bother and a waste of time.
I have only had only
one charger so far that would charge to 4.20v. per cell, 100% full charge each time. After about 10 charge cycles it burned out
Just my luck.
The other chargers I have either overcharge or are inconsistant (uneven termination voltages).
It is important to always check the cells' voltage coming off any charger to be sure the cells are
closely matched.:twothumbs Matching cells' capacities is another story altogether.......
