    Default Test/Review of Eneloop AA HR-3UTGB 1900mAh (White)

    Eneloop AA HR-3UTGB 1900mAh (White)



    Official specifications:
    • Capacity typical: 2000mAh
    • Capacity minimum: 1900mAh
    • Nominal voltage: 1.2V
    • Fast charge: 2000mA
    • Life cycles: up to 1800
    • Self-Discharge: approx. 70% capacity after 5 years




    Maximum temperature raise at different discharge currents: 1A:+1,2C, 2A:+3,3C, 3A:+5,8C, 5A:+11,3C, 7A:+16,6C, 10A:+22,1C,











    These batteries can handle large discharge currents..















    Conclusion

    These batteries have over the years proves to be very good batteries for just about any application I have used them in.
    I really like the low self discharge and the ability to deliver high currents.

    Nice work! Does this mean you'll be doing other NiMH battery tests and reviews in the future?

    I have planned a few and there will probably come other later, but not anything like the LiIon tests.

    The actual test takes about 8 days (0.1A test is slow).

    Your test results corresponds very well with what my MAHA C9000 test my batteries to. I find that the standard AA Eneloops to perform a little on the low side, while the AAAs however have consistently been very close around 800 mAh. I just got some of the latest generation AA XX cells (3UWXB), I have just tested one pack yet, but so far they are really impressive, they gave from 2566 to 2583 mAh. This is up to 37% more than the standard cells. So I'm changing to the XX cells in equipment where more runtime is of importance.

    I really appreciate the time. It's also really nice to see the internal resistance figure. I knew it was low but that is on par with some LiIons. How do you calculate this by the way? Open circuit voltage and voltage under load?

    For NiMH I uses the voltage at 1A and the voltage at 3.5A.

    Excellent test review. HKJ! I've used these batteries for several years.

    Thanks for your hard work for doing different test.

    I wonder if these batteries were brand new out of the pack when they were tested, or if they had been cycled a few times first? It is often reported that eneloops gain performance after a few cycles and if they were brand new it might explain the slightly low capacity measurements?

    I did give them one break-in on my MH-C9000, before I tested them. The Maha did also report higher capacity than I measured, this might be due to the way they are charged.
