Tested at 10A-25A constant current. This cell was purchased from RTDVapor and donated for testing. To prevent any confusion with the eGo-type "batteries", I use the term "cell" here to refer to a single 18650, 26650, etc.
Disclaimer
The conclusions and recommendations I make based on these tests are only my personal opinion. Carefully research any battery you are considering using before purchasing.
Testing batteries at their limits is dangerous and should never, ever, be attempted by anyone who has not thoroughly studied the dangers involved and how to minimize them. My safety precautions are the ones I have selected to take and you should not assume they will protect you if you attempt to do any testing. Do the research and create your own testing methods and safety precautions.
Bottom Line
In my opinion, this is only a 15A continuous discharge current (CDR) button-top cell. I recommend not using it above 20A as it runs at a very high temperature at that level.

- At 10A it reached almost 2100mAh. This is good performance for a 2200mAh-rated cell.
- At 15A the maximum temperature reached 77°C. This is average for a cell operating at its CDR.
- At 15A the AW 2200mAh reaches almost 1100mAh down to 3.2V. The Samsung 25R reaches about 1600mAh.
- At 20A the maximum temperature reached 89°C. This is way too high for 20A to be the CDR. It only had about 50% of the capacity of a 25R down to 3.2V. In my opinion this is a 15A cell.
- At 25A the temperature rose to my safety limit of 100°C and the discharge was stopped. Cells with a CDR of 20A can usually be discharged at 25A without hitting this limit.
- Five additional cycles at 20A showed no signs of damage. But the 89°C max temperature at this current level is much too high to be able to set a CDR of 20A. It reduces your safety margin too much. I am setting a CDR of 15A for this cell.
