Eneloop AAA BK-4HCC 900mAh (Black)



Official specifications:

  • Type: Nickel-Metal Hydride Battery
  • Size : AAA Consumer Type
  • Typical capacity: 950mAh
  • Minimum capacity: 900mAh
  • Nominal voltage: 1.2V
  • Fast Charging Current: 950 mA
  • Charge condition: 0°C - 40°C
  • Discharge condition: 0°C - 50°C
  • Internal Impedance: Approx. 40mOhm(at 1000Hz)
  • Weight: Approx. 13 g
  • Size (Diameter) x (Height): 10.5(D) x 44.5(H ) mm



Maximum temperature raise at different discharge currents: 1A:+2,1°C, 2A:+5,0°C, 3A:+8,3°C, 5A:+12,1°C, 7A:+9,9°C
This is the high capacity version of eneloop AAA battery.











The battery does very fine up to 1 or 2A, but 5A is definitely to much.















Conclusion

This is the first AAA NiMH battery I have tested and I cannot say anything about performance compared to other NiMH AAA batteries.



Notes and links

How is the test done and how to read the charts

They look pretty good, i am shocked then can do 3A without any problems, even 5A doesn’t look horrible but for those small batteries i would not push them much anyways.

Thanks a lot, i’ve been looking forward to your review of these cells.

Thanks a lot!
Please find the time to test the standard (white) AAA eneloop so that we can compare.

I was planning on it, but I have a couple of other NiMH batteries first.

Wow the 2A power curve is fairly nice…I would bet a primary alkaline probably couldn’t push that without dropping out alot faster

Incredible review once again HKJ…awesome!

Do a few alkaline primary discharge graphs as well…yeah…kinda sucky doing a one shot kill of em…but it gives a baseline to compare to (as in what can these rechargeables do compared to the one shot wonders)

Even alkaline AA cannot match a eneloop AAA.
