Orbtronic 3600mah 18650

Got two pairs of these on the way. Has anyone else experience with these? The numbers look super solid to me.

Introducing the longest lasting 3600mAh 18650 Li-ion 3.7V PROTECTED Orbtronic (Panasonic inside) rechargeable battery cell.
Ultra high capacity.
• PROTECTED 3600mAh 18650 Li-ion Orbtronic 3.7V rechargeable battery (Panasonic inside).
• Resettable Protection: Over-current (Activated at 7.5A-8A), Over-charge (Activated at 4.35V) - Over-discharge (Activated at 2.5V) - el. short circuit protection. Protection electronic circuit designed by Seiko. ICs made in Japan.
• Best battery for High Power flashlight users, or for anyone who is looking for the longest run time. Real capacity - The longest battery life you can find in USA today.
• Orbtronic 18650 battery is very safe to operate. This 18650 Li-ion protected cell will automatically cut off current flow if any of the following occur: Short circuit (dead short) - Extreme temperature, Abnormally high current, Over voltage, Overcharge, Overdischarge.

Important - Electronic cigarette owners: Protected 18650 battery cells are larger (in diameter, and length) and are not suitable for e-cig mods.
Powerful high drain 18650 battery cells (without external [PCB] electronic protection) made for e-cig mods are available on Orbtronic.com, and you are welcome to place your order.

That cell uses the super elusive 3600mAH Panasonic NCR18650G cell (which is nowhere to be found as a bare unprotected cell). HJK did a test of that cell here:

http://www.candlepowerforums.com/vb...3600mAh-(Black)&highlight=Orbtronic+ncr18650g

it would appear that this cell is rated somewhat optimistically, with only around 100mAH more than the common 3400mAH NCR18650B. So I wouldn't expect runtime to be ALOT higher than the NCR18650B. But still, the capacity IS higher. It also maintains a higher voltage during discharge than a protected NCR18650B, as seen on the Lygte 18650 battery comparator:

So it would be a good (if somewhat expensive) upgrade from the NCR18650B (and protected batteries based on that cell). I should mentioon that, although this cell is more expensive than most NCR18650B-based cells, it really doesn't cost much (if any) more than many name-brand rewrapped NCR18650B-based cells (like Nitecore).

My Nitecore 3400mah 18650's are re wrapped Pannies? I had no idea I thought they were an actual Nitecore design guess not. True an expensive upgrade but I will also be comparing how they fare in many of my lights vs Olight 3400mah, Fenix 3400mah. Im thinking they will do much better as I just learned my many 3400mah Olight cells are Chinese made not to sound nationalist but Im a true believer in MIJ.

As far as I know, Panasonic is the ONLY company that is currently making 3400 or 3600 mAh cells. So yes, your Nitecore 3400 cells are Panasonics...just like every other brand. Nothing wrong with Fenix or Olight cells, they are based on the same Japanese cell, only the protection circuit and wrapper are different.
