Top Notch Batteries
I remember when Panasonic made the first high capacity NiCad batteries. That was a long time ago and now I see the same top quality from them all over again with LithiumIon.

Battery evolution takes time and consistent testing to make them better. Orbitronic takes the cake when it comes to bringing high quality batteries to my electronic cigarette. These 3100mah 18650 batteries make my Ultrafire batteries look like cheap chinese knockoffs, and they probably are. I did some research and ended up right here on Orbtronics website, glad I took the time to find out who makes the best battery. The quick shipping, and wonderful packaging was impressive, then the 6 hour charge time told me these things were for real. Like Arnold Said, "I'llll be back"....Thank you.

Best 18650 I've ever owned!
I've been using Ultrafire 18650 batteries and I thought they were good untill I purchased a set of Orbtronic 18650 batteries! These batteries last 4 times as long as my old cells and thats good enough for me!

Orbtronic 18650 3100mah
These 18650 3100mah batteries was the second set of batteries that I bought from Orbtronics. As a vendor, Orbtronics has given me the best experience. Their products, shipping and customer service are #1. Not to mention the batteries which last a long,long time. Like I said in a previous review...... Im a customer for life. So with that being said I highly recommend buying from them.

Great batteries.
I use these in my Nitecore TM11 Tiny Monster 2000 Lumen flashlight, and they last the longest out of all the other brands of 18650 batteries I've tried.
These are the only 18650 batteries I will buy from now on!
Very highly recommended battery!
