5 STAR Orbtronics 18650 (3500mah batteries)
First of all let me say that the customer service is GREAT!! They responded immediately whenever I sent an email--even on weekends.
Sal is the tech that I dealt with, good job Sal
I decided to go with Orbtronics after I saw ALL the positive reviews on amazon. No other battery comes close in the reviews. The batteries are packaged very professionally, the corrugated boxes they came in are cut to size and foam cutouts hold the batteries in plastic cases. The prices are fair and they dont rip you off on shipping. I am very impressed.
These batteries are for a Fenix TK75 Torch, awesome light. As for run time I am depending on all the great reviews in Amazon. I will review the batteries again after I have used it awhile.
I give these batteries 5 stars and would buy them again, and recommend them to my friends

Another Killer 18650 Battery!
Well, I received my first 3500mAh Orbtronic battery and it's awesome! Crazy long run time with serious intensity. My EagleTac TX25C2 is 1180 lumens and the Orbtronic 3500mAh cell seems to last forever before needing to be recharged. From my experience with several different 18650 brands, I can honestly say Orbtronic 18650 battery's are the absolute longest lasting between charges of any cell on the market. I've spent several hundred dollars trying out new brands like Redilast, AW, UltraFire, Keeppower, Olight, & Fenix. By the way, Olight batteries are junk! They run out of power quickly. Out of all those brands, Orbtronic is by far the best available.
