TrustFire Protected 14500 3.7V 900mAh Rechargeable Lithium Batteries (2-Pack)

Pros: Works well in my Ultrafire C3 Stainless Steel Cree Q5-WC 5-Mode 190-Lumen Memory LED Flashlight (1*AA/1*14500) (SKU 26122) and my "Akoray Cree Q5-WC 6-Mode Memory 200-Lumen LED Flashlight with Clip (1*AA/1*14500)" (SKU 16607) giving both lights a very bright light.

Cons: Seems a little thicker compared to standard AA cells, and a little longer.
The positive pole is a little short, in some flashlights this could be a problem

Other: Nice batteries with new design, don't know if these are better than the gray Ultrafires

Pros: Good the battery. Worth purchase. The protection fulfils its task and power supply cuts off when there is such one need. A little larger the than battery AA is the size but this does not disturb in my case - they fit ideally. What the capacity answers more or less this the manufacturer passes.

Cons: None yet

Other: The somewhat larger price than different batteries on DX but they are buying worth despite all

Pros: Nice batteries, works great in flashlight sku.28546. This combo gives probably the brightest, cleanest light of any flashlight I have ever owned. Don't forget to buy a proper charger for these also!
Item recieved was as pictured, Trustfire with nice red and black color scheme.

Cons: None, these babies just work :-)

Other: Good value for money, nice size even with protection circut.

Pros: I bought until now close to 100 pieces and all are above 800mAh capacity. Most are around 880mAh (discharged at 1C) so this is the best 14500 money can buy on DX. Protection works well, is good for shorts, and undervoltage. Not tested with overvoltage as I use a pro charger.

Cons: none

Other: Look no further for a 14500. The price is good, capacity as rated when discharged at 1C.

Pros: These protected batteries are great for those who want an extra ooomph to their Cree flashlights that take 1AA/14500.
Charges just fine and is near the rated capacity.

Cons: Does NOT fit the Soshine battery charger! It's a bit too long for it to fit. Also, the protection strip seems a bit loose, as in when you press on it, it makes this sort of "sticking" sound.

Other: These are great bang for the buck batteries. Although Trustfire also came up with the blue and grey versions of this 14500 (and cheaper too).

Pros: The Batteries look as good as the same as AA Batteries and would fit in the same devices. I use them in a AKOray 220 Lumen LED Flashlight, which is a great combination. The Batteries Lifetime is about a 3/4 hour in full power Mode, which is quite long!

Cons: The shorrcutcurcuit on the bottom of the batterie makes it a bit longer! But i wouldn't recommend to break it off, even if the batterie charges and works afterwards, because LiIo Batteries tend to explode during loading, and it seems not to have Problems in most devices!

Other: Buy it to get really cheap rechargable 3,6V batteries for your Flashlight or whatever!

Pros: Got these for my akoray k-106 and some other AA lights I got from this site. They are almost twice as bright as a normal AA. They took a charge with now problems, are protected, and seem to be built with quallity

Cons: They are a little longer than AA. I had some problems right away when I put them into my light. I had to really twist the cap on tight to get it to turn on. Just remember to tighten cap all the way when you first put them in

Other: Nice batteries, powerful, hold a charge well, nice long run times, and a decent price, what more do you need?

Pros: Protected, so very user friendly, especially in a flashlight. Same capacity as the AW 14500. Very inexpensive vs AW's Same lenght as protected AW's

Cons: overrated mAh (AW rate 750mAh and last just as long) cheap looking logo (hologram stuff) longer than AA batteries by maybe 1mm

Other: If you want good quality, safe and inexpensive cells, get those. If you want a brand name, get some 10$/cell AW.. but they are pretty much the same in every aspect. a must for any flashlight owner (that supports 3.7v)

Pros: I own several of this type and size cell and these are the first protected cells i have of this size, they fit my flashlights and lasers without any problem, and best of all they actually seem to be spot on (or very near) to their rated capacity!

Cons: Hmm im struggling to think of one.

Other: Good quality, good price.

Pros: This is a nice way to upgrade a flashlight if it's capable of the extra voltage.

Cons: The longer length doesn't fit very well in my flashlight (zebra). When I first put this battery in my light (after charging it) and hit the button - nothing happened. It was tough to screw the cap on all the way. After playing with it a little though it started working and is a good improvement over 1.5v batteries. This is not a technical rating but I would say the light is around 30-40% brighter. A very visible improvement.

Other: If I continue to have problems I might try to buy a shorter 3.7v battery. But for now it seems fine.
