I wasn't really expecting these to be much different than the name brand batteries and it turns out they are really great! To do a thorough and scientific comparison I constructed a de-charging rig that consisted of a 5 ohm equivalent resistance and an analog to digital converter. I discharged the batteries at a rate of approximately 0.25 watts (the rate did vary some with discharge state). I collected 5 voltage readings across the test rig per second and averaged those down to 1 reading/second to reduce variability. I've attached the results as customer images, but the rundown is this:

Eneloop Batteries, 2000mAh (slightly used through <10 discharge cycles)
Battery 1 - Capacity 1928 mAh
Battery 2 - Capacity 1966 mAh

Amazon Batteries, 2000mAh (<3 discharge cycles, new)
Battery 1 - Capacity 2016 mAh
Battery 2 - Capacity 2006 mAh
