I bought a pair of Ultrafire BRC 18650 3000mAh batteries and charged them together. I got the green "charged" light and pulled them. One works and the other does not in either of my flashlights, a Fenix TK21 Ultimate and PD32 Ultimate. I replaced the battery onto the charger overnight and the indicator stays green but it still will not power either light?Not a huge deal, just curious how this could happen and want to make sure I do not throw out a possible good battery. Thanks!

Maybe the protector pcb kick off, you must get better batteries, or good batteries, those ultrafire are crap, all of them, if I have those lights I will get named brands like, panasonic, sanyo, lg or sony. Check the Good Deal section, there you can find good prices on this batteries...

Earlier I ordered a couple Intl-outdoor Sanyo UR18650FM 2600mAh. They seemed to be a good match for my lights? I do not use my lights very often, the TK21 is now on an AR setup full time and the other is new. I still had the Surefire disposable batteries that I got with the TK21 installed and had not started using the rechargables yet. When I got them 3 months ago I charged them and stored them to be ready once the Surefires died. I just got the second light so I got the Ultrafire rechargables out to use and that is when I found the one dead.
I tried the method below to reset and it did not seem to work. Not sure if I need a certain type of resistance on the wire connecting the negative ends? I used heavy gauge copper wire I had.

If this dont work stay away from this battery, check in ebay or some reliable site for the protected panasonic, you can find a pair for less than 20$
I'm no fan of AW, are too expensive for my taste, you will get better options at better prices...

Stay away from the Sanyo or the Ultrafire??? I got the message on the Ultrafire and am hoping the Sanyo were the right choice?

OK, so I will be good with the Sanyo
You guys need to be careful with these cells. eBay isn't exactly the most trusted place to buy Li-ion batteries. Only because 90% of those vendors are Chinese, and their stock can be questionable...at best!! There ARE some good Sanyo cells...2600mAh...BUT they're UN-protected, so you need to be careful when using them. For "Changchung" to say you're not a fan of AW-(because of the cost)--is ludicrous!! Just be VERY leary, and VERY careful of anything that's less than $15!!

Hi there, yes, I am not fan becuase that, so high those prices.
I have no problem with the unprotected, almost all my batteries are like this. I just have some precautions. Checking the voltage, dont underdischarge, etc, almost all the new lights had under voltage discharge warning, that help a lot.
I buy a lot in ebay, fortunately never had bad experiences, anyway we have paypal on our side.
I bought my last 18650 (sanyo) 2600 unprotected in buyincoins (Lg) 3000 and (panasonic) 3100 protected in ebay well used, no problem at all, and fasttech (panasonic) 3400 protected 19$ the pair shipped... Not received yet... See why I dont buy AW?
