VERY LOW CAPACITY
I have a lot of experience with lithium batteries, and these are my first AAA style cells as I normally use plain brick cells. They came with the standard charge of 3.87v, a good sign, but I had to charge them super slowly at 0.1A to keep the voltage down and get more capacity in which was only 25mAh to reach 4.2v at 0.1A. After the charge it dropped to 4.05v. For testing I ran it down to a safe 3.000v 3 times using an 8ohm then 10ohm then 25ohm load until the voltage drop became very rapid signaling it is about empty. By the way these tend to hold their voltage around 3.6-3.45v average even without a load, kind of low. After the thoroughly, but not too deeply draining the 2 I bought, I charged them for about 80 minutes at 0.1A and put about 120mAh back in. I expected at least 250-350mah for a "500mah". I have to admit they work, but are not powerful. If I was looking to get cheap batteries I would have just aimed for cheap ones, I got mislead somewhere else that ultrafire was very good, now all I hear is how overrated and bad they are. I have them now and don't need high performance, so I'll keep them.
ProsThey work, and can last a reasonable amount of time in low power devices
ConsOnly 120mAh of useable capacity, weak voltage.

Great in my LED flashlight
I have a small, single AAA LED flashlight. This rechargeable battery offered much brighter light. I think it fully justified the risk that it could overload the flashlight. I like it.

The right product at the right price
After calling to get some advice on which 10400 cell to order, I chose this one, and it works perfectly in the chosen application (OLight i7R EOS).
ProsProper size for the device; protected cell; proper design (button top) for the given application

Works in LUMAPOWER EDC LM2 flashlight
This battery works in the LUMAPOWER EDC LM2 flashlight. It is listed as 10440 but is a little bit shorter than the Trustfire 10440 batteries that I ordered at the same time which do not work in that flashlight. These may actually be 10400 type but whatever they are they work in the flashlight.

Powerful
I was using alkalines in my Lumapower LM21 but could not get the full 300 lumen output. When I replaced the alkalines with the UltraFire 10440 what a difference, now I have a bright 300 lumen white light that lights up a room. I have charged it a few times with no problems. I have been using it for a few months now so time will tell on its durability but so far great results and no problems.
ProsPrice, powerfull, easy to charge, good run times
Consnone

Top Notch
I've used several brand's of 10440 in various pieces of equipment with mixed results. When I started using these UltraFire batteries I experienced a remarkable improvement in the operating range along with longer run time between charges. I'm having no problem with over heating under heavier load's, which I was with the other brand's. Highly recommend.
ProsPretty blue colour.

Midget powerhouse
Started using them in several AAA flashlights that I determined would handle the extra voltage,HUGE increase in output, I limit the run time to keep the temp down.But a nice wow demo to amaze the general public.....(non flashaholics).
ProsCheap power packed batts, they last for a long time with proper use and conditioning.
ConsWould like even more capacity, but that's a given.....

Just What I Needed
I was looking for a lithium replacement for the standard four cell arangement in my Kyosho Mini-Z fleet. The power delevery is constant and strong up to the end of the run. I often store the cars for a long time and they hold their power well. They charge consistantly each time even after a lot of abuse.
