Eneloop lite AAA BK-4LCCE 550mAh (Blue)







Official specifications:

  • Nominal voltage: 1.2V

  • Minimum Capacity: 550mAh

  • Cycle life: up to 3000 cycles.

  • Low self discharge: 70% after 5 years



Maximum temperature raise at different discharge currents: 1A:+2,4°C, 2A:+5,1°C, 3A:+6,8°C, 5A:+8,0°C
Low capacity, low self discharge AAA batteries.












Capacity is around 550mAh, depending on load and the two cells matches.















Pulsing 1A on/off makes it possible to calculate the internal resistance during discharge. H means current on, L means current off, measurements are done just after switching the current.



Conclusion

The batteries looks like very good quality, but the capacity is low. They are rated for more cycles than regular eneloop.

Wow! Thanks for quick response to my request. If I ever wear one of mine out I’ll let you know.

Thanks for the review.

Interestingly, there appear to be several versions of this cell, depending on the market. The ones sold in Japan are actually now made in China, and they are rated at 5,000 cycles. On my Opus C2400 charger, using 0.2A discharge rate, they showed capacity of 628 mAh.

I’ve been using them in my cordless phone for the past 2 years or so.

I’ve got some AA lites on order. Guess I like the robin egg blue color. Could you test those too?
