Always use the best alkaline you can. I prefer Duracell or the Costco brand.

I'm kind of having the same issue. The new batteries I have put in, die fast. I have been using regular store bought batteries. I know there are higher power batteries sold at places like Batteries Plus, that are specifically designed for high lumen flashlights. Might be worth looking into if you want to have optimum performance from your flashlight. I recently ordered a Zebralight SC52. Waiting on it now, but also ordered a $10 high powered AA battery to use in it. It was a battery they sell, and recommend. If you still don't have good light after trying these batteries, I would send it back, or try an exchange, because these Nebo Redlines are pretty cool. Good Luck. Hope I helped in some way.

I have the same issues! I have had great success with the 750ma (green) batteries, so I ordered some of these 900ma (blue) batteries hoping for longer life. Instead I got varying voltages, higher than 3.0V that the flashlight did not like, plus, they are slightly bulkier and get stuck in the flashlight. They should be built to the same standard, but they are Not!

3 * 18650 batteries. Like these:http://www.amazon.com/4Pcs-18650-3000mah-Rechargeable-Batterys/dp/B00AQPZM7U/ref=pd_bxgy_sg_img_y

I recommend using the Surefire brand CR123 batteries. They are quite reasonably priced!http://www.amazon.com/gp/product/B000UX93OQ

get these: TangsFire® High capacity 2pcs 3.7V 18650 3600mAh Rechargeable lithium ion BatteriesI bought this flashlight, and got the blue batteries as shown with it as well, and while they are good, the Tangsfire ones I linked are better. The flashlight is a little brighter with them. I tested the flashlight with the blue ones shown and compared them to the Tangsfire ones, and the tangsfire ones last longer and are a little brighter.

You will want to use the 18650 type batteries. I recommend the rechargeable kind. They last a good long time but after extended use (about 3 hours) they do dim considerably. I have the same flash light and am very pleased with it. As a Police Officer, I use it daily on the job.

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.

I've been very happy with the 123 batteries sold by Surefire. Much less expensive than those from local stores, optimized for the type of service seen in flashlights, and so last a long time in use. I have 10 Surefire flashlights.

Any 18650 battery will do. The higher the mAh you buy the in these the longer the light will run between charges. I'd stick with name brand 18650's BTW - Panasonic, Samsung, etc. The low cost/low quality 18650 are certainly cheap but they can be dangerous.

The only batteries I've used so far are Titanium Innovations CR123's and the Orbtronic 3400 18650b here ORBTRONIC 3400mAh FOUR 18650 PROTECTED PANASONIC Li-ion 3.7V Batteries - 10 Amp Dual Protection - For High Performance Flashlights - Button Top - Battery Cases Included No problems with either!

I did not have success with them, only temporarily. Due to higher voltage, 4.2 Volts, they have a regulator that cuts off when ever he wants and your flashlight will go dark, even do the voltage will read 3.2 on the voltmeter.I used them in a NOVA flashlight. Rechargeable batteries made 2 or more years ago with different technology worked fine, and their initial voltage after charging was 3.2 V. Honestly I don't know what are this batteries for, I will not risk an electronic devise with them. I am an electronics engineer. Sorry Tenergy.

alot of folks recommend using nimh batteries and a good charger. Personally I prefer using the Energizer lithium batteries. They last a very long time and I have taken 100's of shots, used the flash alot plus recorded a few videos and the batteries are stil going strong. Alkaline batteries are best for emergency situations only when no other battery type is available. A set of 4 lituium battieries is around $9.

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.

I recommend replacing the 1000 mAh batteries with better ones after the originals wear out. One of the comments when I bought my Moonrays was that, " 3 AA NIMH batteries of at least 2000mah capacity for each light," are better. Nickel Metal Hydride batteries aren't cheap but are worth the price.

My Trustfire High-power Super Bright 8500lumen 7x Cree Xm-l T6 LED Flashlights all function as advertised but ONLY when the batteries are 26650 batteries rated as 5,000 mAh. The 18650 batteries are not robust enough to power the flashlights in all 5 modes.If you still have the flashlight, be sure you have freshly-charged batteries, and invest in some 26650 batteries - Trustfire-26650-5000mah-Lithium-Rechargeables have not failed in use.
