Awesome ability to recharge with a cable

I am very happy with the battery so far. It remains to be seen how long it will hold a charge, but the convenience of a micro USB port for charging is a real plus.

Love the direct recharging

I like that these are rechargeable with the cord versus a separate charger.

good companion to any light

Definitely glad I made this purchase. I work as an armed guard and I purchased this item for the pistol light I use at work in a standalone manner as I dont have a pistol light compatible duty holster and at times the light will be accidentally turned on and drain my battery. These batteries are usually around 15 for a single use variant of the same variety. Def worth the money if you have equipment that utilizes CR123 batteries.

Love these batteries and the idea is long over due. I use them as a back up to my duel fuel Streamlight flashlight, so I can always recharge in the field and no charging cradle needed. Also works great in my weapon mounted light that takes CR123s as well.

Bought 1 extra with my PD25 purchase. Only drained each battery once so far, but I love the idea, and so far they’re working awesome!

Are you dumb? Buy these batteries and dump those CR123s! Save yourself money, come on fool!

These save you a lot of money on 123 batteries if you use your light a lot.

Surprisingly lightweight, holds charge well and takes charge pretty darn quick

High quality and a very great solution. You don’t need a charger, just a normal USB cable to charge this batteries.

Well worth the money as non-rechargeable lithium batteries are $5-6 each unless bought in bulk. I bought 4 and they should save quite a bit of $ over the long run

So far so good. Hopefully they last as long as advertised

I purchased 6 of these batteries, but only 5 of them had the LED indicator working. Called customer service and they were very helpful on how to return the defective one and fill out the warranty sheet. my only problem was that shipping was $3.75 for a battery that cost me $6.50.

Love the built-in port with charge control. With a lightweight solar panel, I can have a backcountry power source.

These batteries seem to last forever between charges. The comparable flashlights achieve a much higher light output with these installed

Very good idea to put a micro usb connection on the battery for charging. Easy as can be. I’ve had very good luck with Fenix batteries and this one seems to be living up to my expectations. I charge it once a week and it lasts the whole time between charges.

Awesome batteries. Bought 3 of them. Highly recommended. I can also charge these babies with my USB without tying up my HM50R Headlamp, (which is also an AWESOME headlamp. Very bright! Also very highly recommended.)

Terrific idea!
John Adams –
I like this battery since I don’t have to bring a charger. Unlike some people in these reviews, I fully understand that, in order to have a charging port and circuitry INSIDE THE BATTERY ITSELF, I give up some capacity. I find 20% to be acceptable. If you don’t, then don’t get this battery. Get the non-U model that requires an external charger.

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.
