Is the flashlight suppose to get hot? I felt it heat up so I quickly took the batteries out they were hot as well, very hot!

See all the fins carved out of Al around the head of this flashlight? They are cooling fins because the manufacturer knows they are needed.

Yes it can. When on high there is so much energy transfer happening between the LEDS and the batteries both will heat up quickly. Using lower settings will help keep things cooler. The heat will not hurt the batteries or the light. But it can get too hot to hold if you leave it on high for to long do be careful. Lower settings will give you longer run times as well.

When the LEDs are driven at or near a full load they will get very hot. If your batteries are getting hot not just warm I'd suggest a quality set of 18650s, there are a lot of rip-off fake Li-ion on the market and a good deal is usually a bad deal for a high power flashlight. Keeppower and EVVA are both brands I trust. Beware of UltraFire 18650's over 3000mAh, those are fakes and fail to measure up. Only buy UltraFire batteries from UltraFire directly.

It gets a little warm if I leave it on while in my pocket. Not hot I leave the batteries in all the time and they hold a charge a long time I love this light

Very hot? It's normal for rechargebles to get warm, even very warm, but not hot...at least not too hot to the touch.

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.

No fires for me. But they did get extremely hot and that was a concern for me as well. When I unplugged them to change cartridge it was very hot!! Unsettling.

Had my charger plugged in for a few days with a battery from a recently purchased yard sale 18-volt drill. The unit was warm to the touch, but not hot. I have charged other batteries and they were warm when removed. The charger changes to a solid light when the battery is charged, and I usually remove it at that time. If it's getting really warm, I'd try a different battery if possible. If same result, then I would contact vendor or B&D as a warranty issue.

mine is set on C and I keep meaning to contact the company to find out. It is warm on 37-38 over that it gets hot. If you get the answer before I do please let me know. No it is batteries

I have not had this problem with my flashlight, it works just fine. Sorry to hear you are having a problem.

When you say "melt" I guess you mean "gets very hot". The problem is with your batteries (nicads) which only last a few years and have long since worn out. You could spend a bundle to get new battery packs (as I did) only to find out that what you got were moldy old ones that had been sitting around in a warehouse for years and wont hold a charge very long. My advice: say goodbye to that old drill and get new one with modern lithium ion batteries. You won't believe how much more power they have.

I've had issue with it getting hot enough. I just got some other tips to try to see if they will work better. I know a soldering gun does get hotter.

Its been my experience that leaveing it plugged in after dark the charge likes to feed back through the carge controler and heat up why i dont know but it does i would reccomend unplugging it as soon as it gets daark just to be safe..it does get kinda hot!

I just bought this. I put both levers down, turned the dial to high, and when they popped up, the entire outside (except the strip around the very bottom) is so hot that you can't touch it without getting burned. I think it would probably melt any plastics that were inadvertently pushed against it. I think I'm going to return it just for this reason, even though I haven't toasted with it.Addendum: My BF was appalled at how hot this became, so he shone a flashlight all around inside, and you can see there is NO insulation between the outside walls and the metal lining the slots. No wonder it gets so hot. I just bought this.

Mine has become really warm when charging but nothing hotter than what you can comfortably hold bare handed. That was after about 4 hours of continuous charging. The battery I was trying to charge must have had a drain on it while I was trying to charge it. I didn't disconnect the battery leads. I use this charger quite often and has worked great for me.

I had that problem once -- but it happened when my batteries were almost dead and the camera shut off on its own, and then began to overheat. I took out the batteries and haven't had that problem again.

I had mine on for an hour or so, and it got hot, but did not overheat. Sorry, Wish I could help.

Over the years I have had a few that got hot when they were plugged in constantly. I started unplugging them when not in use.I don't know what caused it, but they did better when plugged in by themselves on a separate plug.

I just got these, so I have tests to run, just need to find the time with kids and all. I'm still on the first one of two in my torch. It heats up to a warm temperature, nothing dramatic though. When I first charged them in the charger, the led glowed the same color, I believe it was green, the entire time. So I wasn't sure if and when they were fully charged, but I charged them over night and as I stated, the first one has worked fine so far. I'll update about any possible confirmation of circuit protection as soon as I can.
