AW IMR 18650 2000mAh (Red)
- Nominal Voltage : 3.7V
- Capacity : 2000mAH
- Lowest Discharge Voltage : 2.50V
- Standard Charge : CC/CV ( max. charging rate 2A )
- Cycle Life : > 500 cycles
- Max. continuous discharge rate : 10A
- Operating Discharge Temperature : -10 - 60 Degree Celsius
The most interesting parameter with these batteries is the 10A maximum discharge rate.
The cell used can be discharged down to 2.5 volt, in my test I only discharges to 2.8 volt, i.e. I do not measure the full capacity. But then, not all lights will be able to use the full capacity.
The discharge curves at lower loads are not very interesting, many other batteries can do better, but the 5-10A range is above what most LiIon batteries can handle. It cannot match the old AW 1600mAh battery for voltage, but has better capacity.
Notice the short runtime at 10A load, it is only slightly above 10 minutes.
The battery is good battery, but with only 2000mAh it is best used in application that need 5A to 10A current draw and where capacity is more important than maximum voltage.
