Has anyone compared this to the EagleTac 3100mAH 18650? Worth the upgrade?

I own several eagletac batteries and to be honest there is really not much difference from a 3100mah to a 3400mah but it also depends on what you are using the batteries for. But from what I know you do not need to upgrade to a higher output battery when both batteries are 3.7v.

There is a performance gain by using the 18650 battery. I tried both battery options and found the 18650 to work the best. I have a couple other flashlights that uses the 18650's. I purchased a 12pk of the 6000mAh batteries and that is my recommendation. That last for ever. I hope this helps.

I found a good comparison on Ehow that describes the differences and advantages of ech http://www.ehow.com/about_5605853_silver-oxide-vs_-alkaline-battery.html

I have the older model only with 3x AAA battery, However they do not last long, can I use the single 18650 battery in my model?

You have nothing to worry about with the current, improved version. I talked directly with ThermoWorks about this and learned that they have upgraded the unit's circuitry and are now using a better battery. I have had mine for nearly two years, use it regularly, and have not had to replace the battery yet.

I own UltraFire and Tenergy Brand of 18650@3000ma. I have 5 set of them. I only had 1 bad one that won't hold a charge in storage. The rest seem fine I measure the voltage on them to check. After a fresh charge it measure 4-4.3 volts. Then it drop to 3.8,4.1 for over about 2 month. I think like everything a little luck is involve. I read the other peoples reviews and 4-2 stars to me if the price is right I'll take a chance. So far it a good deal Beside they are all made in CHINA no matter which brand. The Trustfire charger works fine too. Voltage on batteries checked before this reply...

I have just cause I had them from another light that I killed and it didn't seem to make a difference. I keep 18650s in mine just because of how much I use it around the house. Just bear in mind that it is NOT 1000 lumen by a longshot.

18650 3.7 v0lt, up to 3600 mAH, 4 each, get ultrafire or surefire for quality. Try onlybatteries.com.

I got the "UltraFire 18650 3000mAh 3.7V Rechargeable Li-Ion Battery + Charger Combo" the battery life is last a long time. Sure you can get a battery with more mAH. It will last longer you will have to pay more. The combo is a good starter kit. If you use the light every day. Buy the better charger and battery. Ps. Love the Niecire ec25 it puts out a ridiculous amount of light.

AAA batteries will die much quicker than a 3600mAh 18650 battery so yes you will get brighter light for longer from an 18650. There are several advantages of the lithium-ion. They are all we use. 1. They maintain a brighter beam for a longer time. 2. You can quickly swap a fully charged battery to keep your light operational. 3. You aren't constantly throwing away AAA batteries.

Yes I use a Nuon 18650 2600 mAh and 3.6V it works great. Two of the cr123 work great also just make sure to use the included plastic sleeve to keep them from rattling. The light itself works great I've used some surefires and 5.11's and I prefer the O-light

It fits fine . Use any color nail polish on the screws to help them stay in from vibration I it's on an AR15. Def get the 18650 Battery it throws more light the battery is better than using 123 batteries but it's nice to use either . I use te light all the time and it is holding up so far

It's one awesome flashlight that uses/requires one 18650 battery. Included are two very lame 18650 batteries and charger. Damn good flashlight, well worth the price, but the batteries don't last more than 30 mins. I've replaced the batteries with some high-end Panasonics, and those go all night if need be. I haven't really used the charger because I already own an Intellacharge i4 pro, I just wanted the extra charger as a backup.

i have not found or heard info of any difference in power. choosing either would depend on the actual battery mod. the cap fitting/pressure of spring on some are tighter and some are loose when fitted with flat top or button.

I use Nitecore Intellicharger i4. It great for the 18650 and 26650. But 26650 take all most all day to charge do to there Large Capasity. But I think they made a new version with a lcd screen on it.

I just checked mine. It has the 18650 Li-Ion Battery in it. (Had to get my rifle out of the case to check it!). If you bought one of the flashlights and they sent the wrong battery, you should get in touch with them. The 18650 Battery DOES fit. (I have 3 of them!)

No, they are not the same battery. The 18650 is a rechargeable lithium ion battery. The cost is reasonable and, having used about 8 of this type battery, I can vouch for their longevity and utility.
