Even if they did that, I'd still buy this for $0.01 over and over again if only because it helps the US Postal Service. 

The low mode should be lower.

Look at it this way... when You recycle them ,maybe you'll find a nice drill pack or laptop battery

Mine arrived yesterday from a UK warehouse, that was fast!

This is not the worst Ultrafire I have ever had either. It weighs in at 40g. Another pair of other Ultrafires I have only weigh in at 38g.

All in all, worth 27p!

Got it today.  Shipped 9/11 from New Jersey, delivered 9/14 to California.

The low mode should be lower.

Just got mine, seems to be of ridiculous internal resistance.

The iCharger measured it at 138mOhms, and gave out only 111mAh at 1A discharge until 3.0V.

Got it today. What a surprise, I thought it’s guaranteed “missing” mail with all the li-ion fuss nowadays.

Oh well, gonna test mine, will update soon.

Well that’s because these are Ultrafires, Chinese mail had a ban on batteries, not spontaneously combustible paperweights. Wink

At least mine’s better than ryansoh’s – came in at 3.81V, charged up to 4.2V soaking 601mAh to get there, now discharging @1A.

It does show high internal resistance, initial voltage drops immediately to 3.64V at start (against ~3.8V+ from good brands).

EDIT:

1A discharge gives 856mAh capacity for mine. For 1c, it’s doing alright Smile

 Still worth it.  1 cent is still a good price for slingshot ammo.

You got a “good” one! I actually got two of my Ultrafires showing about 40% stated capacity once, but the rest much less. A 28.5% of stated capacity is kinda within “normal” for Ultrafire!

Unfortunately ryansoh’s 4% is also “normal”…. Silly

Aint dat the truth!  I would have been surprised if it the results were consistent.

Tore the fake wrapper off and the shell has no printing whatsoever; the insulator on top seems to be glued on coated paper (only seen plastic on pack pulls so far); 65mm casing with thin bottom tacked on.

I finally pulled this battery out of the packaging and did a few first with my hobby charger.  First lithium ion, first data logging charge, first data logging discharge.

 

I don't get what happened during the charge.  It jumped up to 4.2V within 15 minutes, current started dropping continuously, and voltage stayed at 4.2V until the 2 hour mark.  Maybe it's high internal resistance.  I don't have a way of testing that yet.

790 mAh at 1A discharge to 3.0V.

 

The low mode should be lower.

I tested my battery some months ago, and it had ~760-790 mah at 1A discharge as well.

I have 1 Ultrafire Blue and 1 UnarmFire (haha) Blue li-ions. Both of them only gave 320+mAh discharged @300mA.

Low mode and long runtime lover…
