after charging they hold a long time. i used them in flashlight instead of 3x AAA batteries and i looks so, the light is stronger (or AAA were weak :) )
i also use them in electronic screwdriver. i didn´t found any cons yet. Maybe only some of them came uncharged.. Size of them is like standard AA, so you can use them as a exchange for normal batteries.... Read more
They Came charged Positive terminal of both batteries are completely crooked In my opinion the TrustFire Protected 14500 3.7V 900mAh Lithium Batteries (2-Pack Blue) SKU 19626 is a better bargain.
The build quality seems much better at least the finish is much better!
I guess in a flashlight the crooked positive terminal is no problem ... Read more
These are great protected cells I think the stated capacity is pretty accurate Hold voltage well under load Size is pretty close to a regular AA Nipple tip so no need for magnets Protection circuit works Plastic wrapping is a bit "how ya going" in places with PCB's not exactly parallel They are protected but water, fire and puncturing can still burn ...

For inventers who uses existing housing (for example flashlights)for their project is this an ideal product. With a few batteries 7.4-8V and with only 3 about 12VDC. Home made NV equipement can now be powered with only one AA size recharable. No energyloss when not in use, the big trouble with NiNH batteries. The build in PC for protection like shutoff ...

Works well in my "UltraFire C3 Cree 1xAA 1x14500 Flashlight" (SKU 1993) 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. Seems a little thicker compared to standard AA cells, and a little longer.
The positivepole is a little short, in some ... Read more
These protected cells work excellent in the Ultrafire SS Q5 that only runs on the lion batteries.
Runtime on high has been over two hours and the light is still very usable. Not the hot beam at the beggining of the test but still brighter than a fully charged mini maglite.
Great price for 2.
No fit issues, but this light was designed for 14500 cells.... Read more
Its the most common size of battery you can find everywhere. Just be sure your device accept this voltage. Fit perfectly in most AA batteries flashlights. The positive pole sometimes dont make contact. Plastic around the battery breaks easily. Despite the cons, the battery works Properly and last for a good while. It charges with common 3,6 battery ...

Seem like they are good batteries. I prefer protected batts. It has a flange that is not quite round and sticks out so I think they don't work in my units. Didn't fit in my Romisen, well they looked like they fit, but when I close it up they don't work. I think the Neg end is too large it has a flange that is not quite round and sticks out so I think ... Read more
- Has PCB protection to keep your batteries and devices safe
- Price is cheap compared to local stores that are selling them
- Works very well on all my flashlights that accepts this battery - Build quality is questionable as I've got a dud one (brand new) out of the 6 that I bought. However, DX were very quick to replace it. One died around a week ... Read more
Work well in my Ultrafire C3 Cree flashlight. it does seem a little brighter than using AAs, and the extra runtime is nice. I haven't done any run length testing, but I'm sure it has to last longer than normal NIMH batteries. Not really any cons to speak of, besides the fact the mAH rating is overrated, but nothing new there I guess. There needs to ... Read more
