The cell used can be discharged down to 2.5 volt, in my test I only discharges to 2.8 volt, i.e. I do not measure the full capacity. But then, not all lights will be able to use the full capacity.

[size=+3]Conclusion[/size]

This battery uses a good cell, this secures many things:
  • The batteries does match in capacity, i.e. they can be used in series.
  • The battery is very safe.
  • The battery has the specified capacity.


There is not anything to say about this battery except it is a very good battery.



[size=+3]Notes and links[/size]

i have two of these and they're solid batteries.

I wish though that the button top was more pronounced/prominent. otherwise I don't have any complaints :)

Good review, and results very much as I expected. Will the new USPS regulations have an impact on the sale of these cells outside the US? I suspect they might.

Thanks for the review HKJ. I have been waiting for your test. :( Unfortunately, the price will now be increased.

Thanks for the review HKJ. I have been waiting for your test. :( Unfortunately, the price will now be increased.

It's funny, but I was on their site this morning and watching their ad on Ebay today. Their prices were $13.91 and $13.99 respectively this morning. I saw HKJ's review and went back to their website and in the middle of me mulling over the price, it changed to $14.99 and then the Ebay ad changed as well.

Can't blame them for that, as the product seems to test out well and after all, this is America, so why not get a buck or two more?

I ended up ordering a pair of their unprotected Pannie 3100s to fiddle with, but I'm now looking at their 840 mAh Sanyo 14500s and might be ordering a quad for my Xeno EO3 down the road.

I just see that... For that price I choice the AW

Perhaps, but Orbtronic is apparently able to override the natural laws which govern the USPS. I ordered three of these cells Saturday the 12th (For 12.99 each btw). They traveled from central Florida to Nebraska first class mail (Not express or even priority) and were waiting for me when I got home from work Monday. WOW!

okay.... so I too checked out Orb's ebay page yesterday, with $14.99 as the price. So why..just NOW..does it have $1,499.00 as the price :eek:... with more than 10 available. Is that a goof... or are they now selling them gold-plated :confused:.

You are a lucky guy... I was waiting for this review, now I will past, I will preffer the AW instead.

BTW is not a big deal about the li-ion batteries shipping new law, the batteries must be shipped in a very safe way, very protected, well packaged and write outside what is the contained.

Funny thing you said it because I just added 4 in my cart, and when I'm about to pay I realize $6,000 is a bit steep for 4x 18650s.

BTW there is this "Keeppower 3100 mah 18650" which appears in the HKJ battery review thread and did on par with other NCR based protected cells. At $11.50 each it is worth considering.

I've been trying to find these since HKJ's review some weeks back, but haven't seen them anywhere for sale. Where did you find them?

Ah, thank you HKJ. After your review I emailed them and it seemed that they only dealt in wholesale numbers. I'll have a look. Sorry to go off topic slightly.
