Eneloop pro AAA BK-4HCDE 930mAh (Black)





Official specifications:

  • Voltage: 1.2V

  • Chemistry NiMH

  • Minimum capacity: 930mAh

  • Low self discharge: 85% after one year

  • Cycle life: 500 cycles.



Maximum temperature raise at different discharge currents: 1A:+2,3°C, 2A:+5,4°C, 3A:+8,7°C, 5A:+13,1°C
A newer generation eneloop high capacity AAA cell.











The discharge curves look standard for NiMH and are fairly well matched.















Conclusion

This generation has slightly more capacity than the 4HCC type, but the difference is minor.
It is a good NiMH cell, but usually the PRO versions of eneloop has shorter lifetime than the regular version.

Thanks for the review! Your work is always appreciated.

Agreed.

Off topic, but I’ve always found it interesting that I can find AA eneloops (or rebadged versions - the Amazon branded cells seem to be widely accepted as rebadged eneloops) for significantly less cost than for AAA versions. It always makes me laugh (in frustration) and scratch my head when I can easily find AA eneloops for $1.5/cell, but the AAA versions are $4/cell.

Thanks for the review!

I just searched the Eneloop AAA Pro BK-4HCDE on Amazon.com and the 4 pack I found is $10.00($24) more than the BK-4HCCA($14).

The BK-4HCDE has a panasonic-eneloop.eu printing on the pack.So this may only be offered in the EU at this time and imported into the US from the EU.

Thank you, HKJ for a review of the latest of the well known Eneloop family.
Looking at the numbers, and reading your conclusion, one might think this is as good as it gets. That there’s not much room for further improvement left in the existing Eneloop chemistry.
