The right product at the right price
May 16, 2016
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).
Pros:
Proper size for the device; protected cell; proper design (button top) for the given application

Works in LUMAPOWER EDC LM2 flashlight
February 17, 2016
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
March 31, 2015
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.
Pros:
Price, powerfull, easy to charge, good run times
Cons:
none

Top Notch
February 5, 2015
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.
Pros:
Pretty blue colour.

Midget powerhouse
November 15, 2014
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).
Pros:
Cheap power packed batts, they last for a long time with proper use and conditioning.
Cons:
Would like even more capacity, but that's a given.....

Just What I Needed
May 6, 2011
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.
