AW IMR 16340 550mAh (Red)



Official specifications:

  • Nominal Voltage : 3.7V
  • Capacity : 550mAH
  • Lowest Discharge Voltage : 2.50V
  • Standard Charge : CC/CV ( max. charging rate 1.5A )
  • Cycle Life : > 500 cycles
  • Max. continuous discharge rate : 4A
  • Operating Discharge Temperature : -10 - 60 Degree Celsius




This battery is a high current battery.










The battery works fine up to 2A, but is not that impressive with a 3A load.











In this test I do overload the battery and one of the cells looks like it is running out of power.
When calculating the internal resistance I used the voltage drop between 2A and 4A.





Conclusion

I am not that impressed with the high current capabilites of this cell, but because it is better than most ICR batteries, in the same size, I will rate it as a good cell.
