Has any one actualy used 3.7v (4.25volt at full charge) 18650 lithium batterys with this? And it did not burn out?

No I haven't but would sure be willing to give them a try. Do you have any more info on this type of battery?

I used just want it says but the wire broke and I put it back together and nothing. It worked for me for two days. You get what you pay for. This is JUNK!!

Hello, El Jefe, These batteries last a long time in my Rosewill 3 "D" Cell, Cree-LED Flashlight. I don't use the light all the time, but it is very bright, and the charge lasts for months. I use an Ansmann energy16 charger. I have used a pair of them in the ignition part of our kerosene heater, and they too, have lasted a long time. I have never recharged them since they begin lighting up our heater. I really like these batteries.

Replace it with 18650. There are many different types out there. I use the Chinese made one. They are ok as long you recharge them when they are low or out. If not, they will burn out.And, they are cheap in price. Hope this help!

Rich, I use mines in my Fenix TA21 and so far they have held up pretty good, I change the them intermittently, just so if I need it and my batteries are not low or dead

Hans,Nothing has burned out as yet. I pull batteries out of all equipment after using just to be safe. Also Hans, I use a battery tester before we charge after we charge to make sure all is in the green. Have a great day!

I don't know why not? I use lithium and regular batteries for my other devices without a problem as long as it is the same voltage and size. Good lite and powerful and long lasting on even a near dead battery. Finish wears off though.

I did and I am not having any issues. The mAh capacity only affects total charging capacity of the batteries. The higher the mAh, the higher the total charge of the battery (the battery will take longer to drain out). I am not a pro, but that's what it was explained to me a long time ago. I hope it helps.

It takes way longer than the smaller 3.7 volt batteries I have. I have a Nitecore charger and I thought maybe it wasn't working because the 18650's & the RCR123A's charge fairly rapidly. But, last time I charged them, I think the 26650's took 8 to 12 hours or so.

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

I have recharged Energizer lithium AA's in this. It did not say "Bad" or instantly show the red light stating there's a problem with the battery. What I DID notice is that they will only take about a 50% charge,(tested with a multimeter) then show "full". So the answer is yes & no.

I haven't tried a lithium battery, but use the top of the line Duracell. I've had it in my timer for three years and it's still working great.

No not imr. I haven't had a problem with these batteries, and I run sub. Ohm .9 .8 I only use these for back up batteries, they just can't beat an 18650. For the price u can't beat it.

I bought the "IntsunUltraFire 18650 3000mAh 3.7V Rechargeable Li-Ion Battery (Pair) + Charger Combo". It was $10.80 delivered with my amazon prime. They hold a charge well, rated at 3000mAh. they charge fast, and the charger's compact with no parts to lose. I paid $39.00 just for a light that wasn't nearly as bright before this so in my opinion, this light battery combo can't be beat! Especially when you get two of the batteries. Hope this helps you.

Never had a problem with batt life, longest usage about 4-5 hrs but i charge it after that with left over current in it.

I have a old battery pack that would not take a charge. it has 18650 F 22 cells (X6) Google 18650 F 22 it shows Li ion cells . . they are 3 volts the voltage protection card limits discharge to 8.4 volts so it doesn't damage the bulb. you are asking me to remember my electronics from 1967 so I am a little rusty but you wind up with three batteries in series X 2 and you parallel the each 3 cell battery to get 6000 ma
