I recently purchased a over a dozen 16650 2500 mah cells from Orbtronics and I am not getting the advertised capacity from them. Here's a link to the cells and their advertised specifications.

I have a Vapcell S4 plus charger with a test function and none of the cells have scored higher than 1950 mah after multiple cycles. One cell was dead out of the box and would not take a charge at all due to what I assume to be a faulty protection circuit.
I fully discharged several of the cells to test their voltage at 0% and none of them got below 3.15 volts, with most being above 3.2. These cells are supposed to discharge much lower and I suspect this is why they are not achieving their stated 2500 mah capacity.
Is this a protection circuit problem, is this correctable or are the cells just not up to advertised specifications?
