They work in Microstream!
Review by Justin D. on 18 Jan 2024 review stating They work in Microstream!
I've been trying find a 10440 to work in my Microstream and Protac 1aaa. These work! They boost the lumens of both to at least the same as the Microstream USB rechargable. I haven't experienced a lot of excess heat but I've only done limited everyday use testing so far.

Great in my LED flashlight
Review by Philip on 19 Nov 2016 review stating 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.

Review by Ed on 31 Mar 2015 review stating 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 durabil...Read MoreRead more about I was using alkalines in my Lumapower

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 recom...Read MoreRead more about I've used several brand's of 10440 in
