Sanyo Eneloop (AA) 1900mAh test
Excellent batteries, performed 102.0%!!!!!
Remember anything above 80% is fine but this was amazing.
Usually the first discharge is out of the box and the batteries perform a little lower, after charging with the analyzer during the routine the battery is more refreshed and performs almost full.
Here is the data Eneloop AA
I also have to thank Ms Anita Gross from Eneloop Sales & marketing division who sent me samples of their batteries. Excellent customer service (pretty fast too) and they were happy to answer all my questions.

Sanyo Eneloop (AAA) 750mAh discharge test
Out of the box they gave me 100.5% when discharged the second time. Excellent performance.
Here is the data Eneloop AAA 750mAh
Sanyo Eneloop XX (AA) 2450mAh 1C discharge test
If not the best, probably one of the best batteries on the galaxy.
This battery straight out of the box gave me 91% and then after a charge it gave me 97.9%. I'm pretty sure if cycled one or two times more it will reach 100% or more but i am having the analyzer testing two AAA eneloops right now so i may test later.

Samsung INR18650-15Q 3.33C (5A) Test
At 3.33C (5A) loads
At 1C (1500mA) loads
Samsung has this model which has a 18A discharge rate, At 3.33C (5Amps) it performs similar to the panasonic CGR18650CH but only for 17 minutes. It performs with around 96-93% capacity and the temperature is quite low (mostly because of the high discharge rate it didn't bother much). Here is some data at 5A loads
Summary:
1. One Hour Discharge: Pass; Capacity=1,440 Ah (96,0% rated); Energy=4,805 Wh; IPV=3,787V; MPV=3,377V; EPV=2,756V; MPI=5,003 A.
2. Lithium-ion Charge: Capacity=1,416 Ah (94,4% rated); Energy=5,552 Wh.
3. One Hour Discharge: Pass; Capacity=1,398 Ah (93,2% rated); Energy=4,663 Wh; IPV=3,775V; MPV=3,377V; EPV=2,751V; MPI=5,003 A.
4. Li-ion 30% Charge: Capacity=450,2 mAh (30,0% rated); Energy=1,637 Wh.
