Do i need to use a 3.7V battery in order to get the max lumen output? or do regular 1.5V AAA batteries do the trick?

I found that three 1.5v AAA batteries were very bright. But this light is a piece of junk.

Regular AAA batteries do the trick fine. Very compact and bright. Recommended.

If you use rechargable CR123A batteries you absolutely have to make sure they are the 3 volt ones and not the 3.7 because the higher voltage adds up and can destroy the light. So only use 3 volt batteries. This light is an awesome light and great for a lot of applications with low and high mode.

It takes a 3.7 V 3000 mAh Rechargeable battery. You can get a regular 3.7 V battery but they are hard to find. I got some at Battery Plus, or something like that and they were fairly expensive, but the best way is to go to Amazon and find them. I ordered 4 rechargeable batteries with a charger and I think it was less than $10.00. When I got my flashlight I was pissed that batteries didn't come with it & they are hard to find. But the ones I bought worked great & they can be recharged. The flashlight is really bright & I have been very satisfied with the light.

Some of 123a's are @: 3.7v, 3.6v and 3.0v. I would only buy any of the 3.0v to be on the safe side, unless your device needs more then 3v or (6v if you need 2) and so on. Also read the reviews on what battery pro's and con's are like I'm doing that right now. Too much voltage will give you brighter light but will drasticaly shorten the bulb or led's life! I am strongly considering these ones by the way.

I wouldn't worry about the Lumens. I returned them because out of the whole box only one worked. I wouldn't recommend them.

My package says "80 Lumens Max". I love mine. Very bright when batteries are fresh. Just be sure to use good batteries. I use rechargeable and they usually only last me a night or two before the light starts to fade away.

I have a lot of different UltraFire flashlights. All are very bright. if the model does not use the 3.7V Lithium battery, the model is designed for three AAA batteries. I never saw a model that uses AA batteries.

I use the 3AAA batteries because the light intensity is the same but the AAA batteries are Cheaper and easier to change. The light intensity is the same as far as I can ascertain.

Patrick the best battery that I have found to use is the Orbtronic 18650 3100mAh all others I have tried have failed after a couple recharges, I have recharged these batteries 14 times and they still charge up to 4.2 V and maintain brightness down to about 2.7 v. I use the light everyday and I swap batteries about once a week. Hope this helps

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.

Yes, the 3.7v batteries will work. They are bigger than the AA and AAA batteries. And more powerful. Some of these LED flashlight have AAA adapter. But yours doesn't. There not recommended anyway.

55 Lumen Output (Estimated Max Lumen output only - actual performance depends on operation conditions, cells used and flashlight. Much better than original bulb,brighter and batteries last longer.

I've never had mine last 3 hrs on the 820 lumen output. An hour to an hour and a half would be more accurate based off my experience. That's with the surefire cr123s you can find at lowes and some cheap 18650s.

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.

Although this flashlight supports 3 batteries, only 2 are needed. I have a few of these flashlights and only one of them came with the extension tube for a third battery. This is not needed in my opinion unless you want a longer flashlight. There was also no improvement in brightness with the third battery. If you still want to use the third battery, just charge it separately after the other 2 are charged. Enjoy

Don't Know The Lumen Count, For A 3 AAA Powered Light Its The Best I've Had, the Battery Life Is TheTrade , Worth It In My Opinion

I used mine with 1.5v AA's and one 1.2v AA rechargeable and it works, albeit, with less light output.
