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

That's a good way to put it...yes.Overall, they are like oversized AA batteries. They do, however, hold a charge very well...especially for things like tactical flashlights, etc.

There are certain Cree flashlights & other Cree lights that use that type of battery. U just have to search which ones. Hope this helps you.

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.

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.

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.

Sorry but I have the lithium ion rechargeable version. Call streamlight they are top notch and if your wrong or there is a problem with the flashlight they will stand behind the product instantly.

I don't trust alkaline anymore. Had more than my fair share of ruined electronics from the leaking batteries. I have used NiMHs since then and never had any trouble. Get Eneloop or any other LSD NiMH's, they work the best and you can store the flashlight with the batteries without ever worrying that alkalines could ruin it. Just keep an eye on the voltages and recharge every 7-10 months depending on whether you use the flashlight much. If you use the flashlight a lot you will most likely need to recharge the batteries more often.

Li-ion rechargeable 18650, i personally use 5000mAh batteries the higher the mAh rating the konger burn time you will get on a charge. Since I utilize this flashlight exclusively for scuba diving mostly at night the length of burn time is important to me. There are several packages of these batteries on amazon is you search for "18650 battery" . I hope my somewhat longwinded answer helps you. As a side note the light wirjs great to depths of 130' mine has roughly 50 dives to that deth. Make sure that you utilize silicone grease on the o-rings befire submerging the light.

4pcs Ultrafire 18650 3000 mAh 3.7V Li-ion Rechargeable Battery + 1pcs charger ComboThey are cheap and work great. I use this flashlight for random things around the house. I haven't charged the batteries for 3months and still works great. Hope that's helpful.

Yes they are. They are closer to the size of a C cell battery but twice as long. They are the same type of cell that is in laptop battery packs. If you search 18650 you will find the batteries and chargers here on Amazon for very good prices. All the Ultrafire batteries I have bought work great. This is by far the best of the best when it comes to budget flashlights like these: http://www.amazon.com/UltraFire-WF-502B-XM-LT6-Flashlight-Clip/dp/B006LVBDNU/ref=sr_1_3?s=hi&ie=UTF8&qid=1364293375&sr=1-3&keywords=ultrafire+502b

The batteries are "Ultrafire" BRC 18650 3000 mAh. 3.7V Li-ion Recommend an extra set. Flashlight uses the power. 20 to 25 minutes of run time and it starts to dim on full power.

I now own 4 Fenix PD35s. $70 here on Amazon. Orbtronic 18650 3,400mAH rechargeable batteries with intellicharger 4 ver 2. About the best light for size and the ability to set a intensity and have the light turn back on to that setting is the best thing about it. Bright too. Go to Fenix.com to see what they have but I know which one I like!

One of the four I ordered had a small charge which ran out in a half hour or less. Whereupon I charged all four batteries. In my flashlight each one normally lasts several (2 to 4) weeks when used about five to fifteen minutes per day. My flashlight is rated at 500 lumens. I am very pleased with the batteries.

Jared, I use the 3-Volt 18650 batteries in just about every flashlight and Laser I own. Never had a problem with them. Just make sure you use the right charger designed for them, to re-charge!

With all due respect, if you do not know what a 18650 battery is, you should probably look for another flashlight that uses AA or AAA. There are a lot of possible dangers associated with this type of battery if you do not fully understand it. There is a 4 dollar flashlight on Amazon similar to this that uses a single AA battery (search for "cree flashlight" - FordEx Group is a popular one).

I use the Surefire A23 batteries. When I purchased, I also purchased a box of these batteries. I have not yet had to change the original set that came with the light and have used it mostly on low output, but about 1 hour total on high output. I have had the light for 2 months now.
