EnerPower 18500 2000mAh (Black)



Official specifications:

  • Nominal voltage: 3.6V
  • Nominal capacity: 2000mAh
  • Minimum capacity: 1900mAh
  • Charge: CC: 1330mA, termination 33mA
  • Discharge cut-off: 2.5V




This is 18500 cells, i.e. 15 mm shorter than 18650 cells, this usual means a significant loss in capacity. With this battery the loss is not that bad.











The two cells tracks fine and has nearly constant capacity up to 3A load. This looks good.















Conclusion

This battery has good performance and good capacity, I will call it a very good battery.

Again thx HKJ, for another invaluable cell test.

Your capacity test suggests, that the Panasonic NCR18500 is truly used here, as no other 18500 cell you can read of can reach anywhere near 1900+ mAh. The NCR18500 is on the market for quite a while now, but this cell from Enerdan is the first protected version.

I don’t see it offered anywhere yet, neither at the Enerdan website nor at their presence on Ebay or Amazon. I presume you got it directly from Enerdan… any hints on pricing or when it will available?

I will suggest writing an email to Enerdan and ask.

I did.
I might be just a bit impatient. J)
Had been hoping for a protected version ever since the bare NCR18500 hit the street.
