The cell can deliver about 2A before it starts to loos capacity, this matches fine with a 1.4A rating.

[size=+3]Conclusion[/size]

For high capacity 16340 batteries these looks good and they are very short for protected batteries.

Thank you HKJ for doing the testing on this product. It is posts like these that make Candlepowerforums an invaluable resource for newbie flashaholics like myself. I was able to look up these batteries and get an idea of how well I can expect them to perform in my newest flashlight. Keep up the good work and thanks again!

FWIW my newest flashlight is a 2017 edition EAGTAC D25C Titanium with the Nichia 219 Emitter.

Fenix ARB-L16-700 vs 700U (Built in Recharge)

I have a couple of these and so far they have worked well. I was thinking of getting a couple of the Fenix 16340 700U with the built in recharging port for when traveling light and don’t want to carry a charger. Has anyone done testing on the 700U in comparison?

I have the one that came with the CL09 lantern. Capacity wise, they are both 700mAh batteries and that pretty much coincides with the one run time test I did, so I think the biggest concern is battery length. Fenix is only charging an extra dollar over the other 16340 battery and so that seems very fair. Personally, I just go with the regular 16340 batteries.......but I see nothing wrong with those that like having that feature built in. I think the only gotcha would be if its too long for a 16340 light that is rather snug to begin with.

Thanks for the info. I did not realize there was a length difference which is good to know.

Since the AW flood and factory shutdown I have moved to these Fenix batteries. Purchased four initially and recently purchased another two for a total of six batteries. Over the past 6 months they have worked quite well in my HDS and Olight single CR123 lights.

I am not measuring capacity but simply charging and discharging the batteries through normal use.

Is the diameter of the 700U really 18.6mm? If so, it won't fit in my Elzettas.
