    I bought 6 of this batteries recently and conducted some experiments. It’s indeed really convenient to have the charging circuit integrated into the battery itself, making a travel simpler since you no longer need to bring a separate charger with you. However, this product seems to have LOWER capacity in comparison with its predecessor “ARB-L16-700” (without the built-in charging circuit).

    First, I measured 3 of the predecessor battery ARB-L16-700 (0.5A charging, 20mA cut-off, then 1A discharge to 2.75V):

    716mAh 2.368Wh
    723mAh 2.408Wh
    729mAh 2.491Wh

    The capacity of the predecessor battery is as rated, this is good. You may find similar results in HKJ’s review here: http://lygte-info.dk/review/batteries2012/Fenix%2016340%20700mAh%20ARB-L16%20(Orange-Black)%20UK.html

    Then I measured all my 6 samples of this ARB-L16-700U battery, charged with the built-in charging circuit:

    600mAh 2.046Wh
    584mAh 2.013Wh
    564mAh 1.921Wh
    519mAh 1.741Wh
    564mAh 1.882Wh
    585mAh 1.914Wh

    Then I measured them again with the same changing conditions as ARB-L16-700:

    610mAh 2.101Wh
    602mAh 2.087Wh
    593mAh 2.034Wh
    586mAh 2.000Wh
    584mAh 2.013Wh
    596mAh 2.049Wh

    I gained a bit more capacities this time, but the result is still far from my expectation. Also, it looks like the charging circuit of my 4th sample is not good.

    Obviously ARB-L16-700U has a different cell core with ARB-L16-700, and this new cell core has about 20% lower capacity. This is UNACCEPTABLE.

Ambassador: Tactical

Simplified Power – 700U Rechargeable Battery Tactical Ambassador, Erik W. gives his thoughts When picking a light for tactical or EDC use it’s easy to overlook charging style or even battery.
