    Default Test/review of Sanyo UR16650ZTA 2500mAh (Magenta)

    Sanyo UR16650ZTA 2500mAh (Magenta)



    Official specifications:
    • Rated capacity: 2330mAh
    • Minimum capacity : 2380mAh
    • Typical capacity: 2500mAh
    • Nominal voltage. 3.7V
    • Charging voltage: 4.35V
    • Charging current: 1190mA



    Test at 4.35V charge voltage



    This battery size matches two CR123 batteries in diameter and length, but has lower voltage. In some cases it is a very good replacement.










    The cells match fairly well and can deliver 5A, but not 7A.















    Test at 4.30V charge voltage



    Reducing the charge voltage means about 80-100mAh less capacity.

















    Test at 4.20V charge voltage



    With a regular 4.20 volt charger the capacity is reduced 260-280mAh.



    The cell needs to warm up before it can handle a 5A discharge.















    Conclusion

    This cell cannot match a 18650 cell, but when the slightly lower diameter is needed it is a good cell.

    More than 1000 reviews of batteries, charges and other stuff.
    Compare 18650 LiIon batteries or smaller (RCR123, 16340, 14500, 10450) LiIon batteries.

    Thank you! I've been waiting for this. I love this cell, run it unprotected with a 3.7v xenon p60 and it's light years ahead of my former protected aw 17670. Plus I've always liked the concept of the higher voltage chemistry, whether or not it's practical, it's effective for incandescent use.
