I bought two AW 18650 2900 mAh in 2011. I used them in my lights until about a year ago, at which point I charged them fully and put them away.

A few days ago I bought a SkyRC MC3000 charger, so I decided to do a full discharge to check the remaining capacity. I discharged them at 1A.

Cell 1: 2563 mAh
Cell 2: 2612 mAh

I then looked for a review and found this:

The stated capacity for a 1A discharge is 2656 mAh.

I think that pretty darn impressive.

I have put a storage charge on them now, because I have no use for them right now. Let's see how they do in a few years
