What brand Li-ion batteries to use? Have tried 2 brands, UltraFire & GTL.. Light gets way too hot to hold in 3-4 minutes, then lose power. Not acceptable. Any suggestions?

I just use a regular Energizer or Duracell and it works fine. I get the batteries from work and one last a month or two using the light maybe a couple of times a week.

I use Energizer, my light has no appreciable change in temperature. Are you able to say if it is the 'light' (LED) or the battery that's gettinig hot? I suspect it is the battery. If so, then the battery getting hot would be the result of excessive current draw (think of if you've ever shorted/briged a battery, both the battery & conductor get very hot), and the battery itself becomes weak/dead. All that to say this:If the battery is getting hot, then the LED is too much load for it - consider using a battery with a higher mAh (milli-ampre-hour) rating. If the 'Light' (LED, or any other part of the torchlight assembly) is getting hot then the unit (flashlight or its components) is defective.

I am currently using TrustFire batteries, but thinking about ordering Panasonic. The TrustFires to warm up, but not to the point where it is to hot to hold. Are you sure it is the correct battery. I know there is a 3.6v n 3.7v battery, both being a 14500. Maybe that has something to do with it... And fully charge the batteries when u get them in. A lot of times they come with a 1/2 charge.

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...

Good idea but, no low battery indicator light. As you suspected, at high intensity (1600 lm) the light works for a little over two hours then simply shuts off. However, long-term solution to this problem involves purchasing 2 (two) rechargeable 3.7V & 6000mAh; Li-ion protected with PCB (model #: 26650 &#8776; $16.00 for a pair). Of course, the final step in circumventing this problem is purchasing a recharging unit (the unit made by 4Sevens recharges a single battery in &#8776; 1 hour). Finally, these are very robust and versatile flashlight available to the public. Hope this assist you in making the right purchase for your particular needs Respectfully, Michael O'Grady

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!

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 only batteries I've used so far are Titanium Innovations CR123's and the Orbtronic 3400 18650b here http://amzn.com/B00BJ8W3KC. No problems with either!

Good Morning, I am scared to say that it will take any battery but as long as its a quality 18650 you should be safe. I just checked to be sure and dropped a few different style 18650's into the bore and all worked. The light comes with the Fenix ARB-L1t 3400 + I am tossing in 2 Xtar CR123a's. Thanks, Shane

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.

http://www.amazon.com/gp/product/B00AQPZM7U/ref=oh_details_o02_s00_i00?ie=UTF8&psc=1 I bought these ultra fire in the link above. Just as long as you charge them all evenly and dont mix batteries youll be fine. Oh and by the flash light a great! The quality surprised me. Really bright, I can compare to NITECORE TM11 but way cheaper. So when you drop it you wont care to much

18650 type. Get some quality batteries like Sony VTC5's, avoid any of these you can see on amazon called Ultrafire or anything like that.

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.

The best batteries in my opinion are the SureFire 123A lithium 3 volt batteries, They are very reasonably priced. I have another make of flashlight that came with a well-known brand of batteries and I replaced them with the SureFire batteries. The beam was much brighter.

Use Surefire C123. Have purchased off brands and they have not lasted as long as the Surefire.

Any rechargeable AA will work. The ones with the higher mAh ratings will likely hold a charge longer. I've used different brands without noticing much difference. I would just avoid the cheapest, unknown brands.

The Nitecore charger is actually a great charger, it just sounds like you got a unit that was bad. As far batteries, the research I've done suggests that a lot of them are actually the same - just branded with whatever company is selling them. I'm not sure if they sell on Amazon, but I have had excellent service with a place called Orbtronic. The Orbtronic batteries work very well and I've never had a problem with them not charging fully. I also have a couple of EagleTac branded batteries for my EagleTac flashlight. I honestly can not tell a difference.

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.

18650 Lithium Ion battery. Buy Panasonic brand, NOT Ultrafire. You will need a charger for 18650 LiIon batteries, as well. Ensure that the flashlight has the correct O-rings in the head and tail ends of the battery barrel and this light can be used to 100 feet of depth without a leak. I have put up to 50 dives on it and no problems.
