Fenix Micro-USB Rechargeable Battery Review
Erik W.
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. Features like size, power and rail adoption often eclipse some critical features. Even more so if you need a backup light (everyone should) or […]

So far the battery seems do it suppose to.

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.
