Also, how old are the cells, i.e. when did you purchase them? Li-ions degrade over time regardless of whether or not they are cycled.

Oh wait, are the capacities posted in the OP not the current capacities, but just the original ratings? That changes things a lot. I think you'll have trouble charging $6+ per cell for used cells with no capacity test. That's basically retail pricing for new cells.

Default Re: FS Lithium Ions 18650s

Something worth understanding -

Hitting 4.2V with no problem, says nothing about the capacity of the cell. Cell capacity degradation doesn't prevent the cell from charging up to 4.2v.

ONLY a discharge test will tell you how much capacity is possible with a cell.

I have dozens of cells that charge to 4.2V, but hold only 500mAh, etc.

Not hitting 4.2V with ease certainly means there is a problem, but that doesn't work in reverse. Hitting 4.2V doesn't mean the cell has it's rated capacity (and if it's a used cell, it likely doesn't).

I say this having harvested literally 200+ 18650s over the past two years, recycling the bad ones, and using the good ones.
