They meant to say that you’ll get 5000mah for all 8 combined :Sp

How does an “educated” person know that this battery is fake?

There are lots of ways to become “educated” about these batteries being fake. Here are a few:
  1. The most certain way to learn is to buy them and test them for yourself. There are methods and equipment to find the exact capacity of the cells.
  2. The highest quality brands don’t go over 3400mAH (Edit: 3600mAH) per cell. These are big companies that are in competition with each other. If they could get to 5000mAH per cell, they would. They don’t. Yet these cheap cells make it there?
  3. There are websites filled with people who have tested lots of different cells. This forum is one of those places. Reading up in places like this is the easiest way to learn.

I recently tested 4 of these in the red wrapper version that a colleague from work had bought.
They ranged between 880mAh and 1240mAh :Sp

How could anybody be stupid as to buy those 5000mAh cells when these are available for just a little more.

I have some that say 5600mAh on them, but those 8800mAh take the cake!  I'll have to pick up some of those.

The 5600mAh Ultrafires I have are also much lighter than any other Japanese cell I own.  I have been saving them for my own personal use instead of offering them for sale because I can't find anything that can match them.

Much lighter than other cells? I wonder if those cells are fake cells with the tiny battery baggie inside surrounded by mystery powder.

Nah, they have so much energy they possess negative gravity. I believe that fully charged they hover.

I have purchased and tested these batteries and I was a little disappointed. On my IONFIRECHARGER 208B they recordered 6500mAh at 5 amp discharge. Frown

No need. Just grab a few dead cells and have your own wrapper made.

That’s right!
I ordered some of the UltraFire wrappers from FastTech so that I can wrap all the dead, spent cellls I get from the recycle bins and sell them on EBay.

And just before I hit the order button, I realized that I shouldn’t order the BRC 4200 wrappers

but rather the BRC 4800 wrappers.

They don’t cost any more but I can sell BRC 4800 cells for more money. Pretty smart aren’t I? Wink

i still say…

i would think it was “very witty” to buy a bunch of NOS laptop batterys to reclaim the half decent capacity cells? and get wrappers for them to become…

“SH!Tfire brand !”

oh, come on, you KNOW youd have to buy a couple just to be funny showing them off, lol…

I tested two red wrapped 3000mAh Ultrafire 18650’s in my Opus BT-C3400, neither of them broke the 500mAh mark… and they weigh 20g less than a 3100mAh Orbtronics.

Probably.. I’m not really using them, and have them with my other 18650’s at long-term storage voltage levels… I dont really feel like ripping them apart to find out.

I got back into this hobby after visiting my old stomping grounds (CPF), and reading about xxxfires venting, turning their hosts into pipe bombs or primaries venting HF acid fumes, permanently ruining the lungs of the poor guy that inhaled the smoke. Until a couple months ago, I had DX Trustfire 18650s from 2007 (I always mark my batteries), and never had a problem with them—other than capacity. I always charged them @ 2 amps with a home made charger and never discharged over 1.5 amps.

I’m not sure I’m any safer with quality batteries, because now I’m building FET DD lights that strain the bejesus out of the batteries, and my LiPo experience says that’s a recipe for releasing the magic smoke.

OK, thanx for confirming about my POS UltraFire 5000mah batteries. It doesn’t make me any happier that others bought these, but at least I’m not alone.

With my new Opus charger I decided to do some battery testing. I found near 950mah for them. In my defense I didn’t know any better when I bought them and I just wanted to inexpensively test the technology. I’m discharging all 4 of them for long term storage in the shop refrigerator. Maybe I’ll give them out when someone needs a light and a battery. They’re good enough for that. I turned one of my flood type lights that I’ve been using every night for the past month or so into a 2 cell from a 3 cell. With these batteries in the light I couldn’t get it to go into hi mode. Back to 3 of the junk UltraFire cells and it did. That’s what first clued me in. My quality cells work in that light, with 2 cells only, in all modes.

Testing new batteries that I got from Mountain Elec’ I find that they all meet or exceed what’s claimed for them. There’s a lesson there somewhere.

Very bad idea, these are not only low capacity, but also dangerous. Giving them to someone with little experience with Li-ion could result in a disaster…

WILCO, thanks for the heads up. I knew they were garbage, I don’t know they were dangerous.

Are they only good for recycling?

Allow me to rephrase that… what would others do with them? If they’re dangerous I don’t see much use for them, correct? I certainly don’t think it’s worth keeping them in the refrigerator thinking that time will make them better.
