UltraFire Protected DOA any fix?

[Big Bad]

I got 6 Ultrafire CR123's (3.6) and 2 18650's off Ebay and when they showed, one of each has about 1.1 volts and will not charge up on my Ultrafire WF-139 charger. The other batteries are fine, is there any way to save these two, or are they dead forever?

Thanks in advance,

Mitch

I got four trustfires from Kai... One of them read 1.7 volts and wouldn't charge on my Ultrafire chargers. I got a Pila and it charged up fine!

Do you know any other flashaholics?

This happens a lot with Ultrafire cells, which have the worst reputation possible. You should not even attempt to charge these cells if the voltage is that low - this would be dangerous.

Yeah, I forgot to come back to mention. 1.1 is cell damaging low voltage.

The ultrafire cells are inexpensive enough that it would be safer to abandon it and try again.

It might have something to do with the protection circuit... if it doesn't work after you put it on the charger, it's probably not worth the risk.

Thanks for the feedback, sorry it took so long to get back to this.

I ordered 7 more CR123's from Battery Junction plus a 18650. In that order four of the CR123 and the 18650 were all bad as well. So my cheap Ultrafire batteries have cost me lots of agrivation and I have to pay shipping to two different companies on top of it to return the bad product.

This Sucks I'd recomend everyone stay away from these!

Try AW batteries in the bst forum.

If the cell really was at 1.1 volts the protection circuitry should shut off, so you'd see no voltage whatsoever. So it's possible the cells are fine, but the circuit is acting up.
Here's what I would do (read: do it if you want, but don't come crying to me if your cell nuclearizes your city ): apply, say, a 3.2V power source to the cell for a few seconds, then measure the output. If this jolt of power is enough to reset the circuitry, you should now have normal voltage readings.
