I can't give you a specific time these last, but I have had excellent performance out of them. I use them at night to light up my camper and I have been out as long as two weeks and they made the trip on a single set of batteries.

A reviewer on the trustfire 26650 batteries said that the ultrafires that claim 6000 mAH are more like ~3200 mAH. ymmv, but I've never seen any of the 'fire' branded batteries actually reach the claimed capacity.

It comes with two 18650 3000 mah batteries. If you order 18650 (5000 mah) batteries they last longer. I have 10-12 of these flashlights and have never had any problem.

The battery is pretty long-lasting. I don't know how many hours you can get out of it, but I use it as a modeling light with my speed light flash, and after using it continuously for 3 hours, it still has a good deal of oomph left. No noticeable weakening of the beam. The only thing to remember is that the battery dies quickly when it starts weakening. I think this is the best light I've ever bought -- nice and bright, and plenty long-lasting.

The batteries that came with it lasted about 50 hours for me. Then the light started to get really dim.

It depends on what mode that you are using it on and what temperature that you are using it or storing it at. I have experienced four to six hours of heavy use. I try to take the flashlight inside if it is below zero but sometimes forget. The quality of batteries will also influence the power and longevity of the beam. Go with premium AAAs.

NI-MH AAA 900mAh 1.2 volt led lenser batteries, they last a long time, I use the light every night and recharge them everyday. Trust me this is a great light.

The higher 1000mah batteries will do just fine & when fully charged will allow the lights to stay on longer. I replaced my 800 mAh batteries with these & the lights are bright again & stay on all night long.

Not sure about the the C rating on these Ultrafires. I've got two sets that I use in two Klarus XT10 LED flashlights putting out 800 Lumens - I get about 1.5 to 2.0 hours on high from each battery. The bottom line: if you're using a similar flashlight for patrol where you need the light for up to several hours during a shift - consider a more expensive battery. For utility or homeowner use I recommend the UltraFires and will buy them again. I have had very good luck over the past two years with them.

I use generic, dollar store batteries. With one AA battery, stays really bright for about 40-50 minutes. After that, the light grows dimmer over the next hour of use. I haven't had any problems with this flashlight.

www.amazon.com/Ultrafire-Lumens-Zoomable-26650-Flashlight/dp/B0092Q1N7W is a great use of the batteries. You will need something that takes the 26650 battery and a charger for the batteries to use them.

I'm sorry, but I can't answer that question, since I never timed it. I can say that this is a super bright flashlight, with a beam of great range and width. I mainly use it to keep tabs on what my dog is doing in my back yard, and it lights up a great swath of the yard. I have been more than satisfied with the duration, and recharge the batteries about once a week, but I cannot quantify the battery light in terms of "How long does it last @ 4000Lm?". I have three sets of batteries, so I can pop a fresh set into the flashlight if its brightness begins to wane. I can say that it does not seem to have a sharp cutoff - the brightness just begins to slowly diminish.

Matt, Buy the Trustfire 26650s if this is the 7 or 11 led torch. I own the 7 @ 8500 retina melting lumens. It will work on 2 or 3 18650s or 26650s. I use 3 26650s an they last hours on high. This beast lights up a whole acre! Don't forget to get the universal battery charger.Steve

Radio Shack Brand Ultralast #18500 Lithium Phosphate 3.2V Battery. I dont normally do this but i am suggesting you return that flashlight while u still can. I had purchased two and had to return one almost instantly after receiving it and the second is dead. No matter how many diff fully charged batteries i replace in it, it refuses to work. Trust me SEND IT BACK. Pelican makes a less exspensive dive light that works very well.
