OK but not as powerful as I thought

Pros:The thing is that I ordered one pair of these, as well as a pair of these: http://www.dealtoworlde.com/details.DTW/sku.26124 Just to check which were better.I just feel that these are cheap rechargeable li-ion batteries, nothing more. CHEAP. These were acting as a 1.5v normal battery after being charged fully, the other batteries CLEARLY was much better.
Cons:- Did not (on my Ultarfire C3) perform better than a rechargable 1.5 nicad battery (slightly better but not much).I would recommend anyone thinking of getting 14500 batteries for their flashlight or similar to go with the Trustfire 14500, 900mAh batteries; http://www.dealtoworlde.com/details.DTW/sku.26124 - than these ones. The Trustfire ones are the way to go. POWER!Sorry DTW, but these were my first dissapointment in all items I have ordered. They act like normal 1.5v rechargeables :(.
Other Thoughts:Go with Trustfire!
Bottomline:Good rechargeable's, but do not hope for some powers (3.7v) from these..... Unfortunately.

Good 14500 Cells

Pros:These seem to be pretty good 14500 cells.Unlike a lot of protected cells, these are not longer than the 50mm standard size for 14500 cells.They work well in my TL3 Mini-M@g hotwire, and fit with no problems, either in width, or length.
Cons:Build quality is so so, but probably better than average in this price range.I have not actually checked their capacity, but I suspect it is somewhat less than stated on the side.I have not tried these yet in my Mini-M@g with the H-1499 bulb, they may lack enough "oomph" for that setup.
Other Thoughts:The best thing about these unprotected cells is that they are no larger in diameter, nor longer than typical 14500 cells. They fit in everything that is designed for "AA" cells. Check before you try to use them in "anything" though, as the voltage is considerably higher than an "AA" alkaline or NiMH/NiCd.
Bottomline:These seem to be good 14500 cells at a very reasonable price.

Pros:Good price.Useful for direct driving 1XAA torches.Have a raised positive node (like the new grey Trustfire 18650) so no need for magnetic spacers.
Cons:Have 10% more volume than 16340's (RCR123A) but the capacity seems to be worse.Tempting to try them out in 1.5v torches (damamged a switch in one of mine but repaired it with sku.5618).
Other Thoughts:My Romisen RC-G2 had flickering issues so I rewired it for direct drive and hoped that would fix it. It handles the current fine, however the runtime is as bad as if it were powered by an RCR123A.
Bottomline:Good performance mod.

I'm happy with my purchase!

Pros:One came 4.00V and one 3.87V. At least neither was dead.They do what they are supposed to, making my AA/or Li-Ion light brighter like the instructions said.Extra words to get 1000 characters.More extra words as my first try said not enough.
Cons:I have a DSD charger and I had to do some fancy stuff to charge one.Can't find anything else to dislike!Blah, Blah, Blah. Extra characters.
Other Thoughts:Nothing really. They do what I ask of them.Gray wrapping. Fit anything I've tried them in.
Bottomline:If you need 4.2V in AA size you could do much worse!
