I purchase the batteries and just put them in my Surefire flashlight and they blow the P60 bulb in it. What can you do to help fix issue?

These batteries are for cameras. Doubt if they're intended for flashlight use. Flashlight batteries are usually 1.5 volts and these are 3.7 volts. Go figger...

The driver in the drop-in most likely was not rated for more than 4.2 volts. You'll need to replace the drop-in or if you're able to just replace the driver with a better one since the original driver usually only provides 1/2 the amperage to fully power the LED.

I have them in my lasers and my flashlights. then again I don't use 60 lumen flashlights they are 200 and up.

First, what batteries came with the flashlight? Second, these batteries are rated at a max voltage of 4.2 VDCif you charged them with a charger with greater than 4.2 Volts, it with overpower the Diode and blow it.White diodes are voltage sensitive and anything in excess of 4.2 volts with blow them quick. Check the outputof your charger to ensure that its 4.2 VDC Max. Let me know thanks perry

I just unscrew the flashlihgt from the shaft. When you do this it will reveal a "button" battery. Pop it out and replace. Reattach the flashlight . That is the best I can do for you. Jim

I have bought a dozen of these flashlights over the last five years. Initially, they all had the same problem, the switch would only work if held part way on. The answer below this from R. Hennigh about a loose retaining nut is worth a shot, but for all twelve of mine, here's what I had to do, and what I'd recommend you try first. Unscrew the head and tailcaps of the flashlight and remove the battery. Hold the body tube up towards a window or a lamp...can you see through the tube? If not, take a long drift pin, a long dowel rod, anything that can take a good whack and not break...insert into the body tube from the tail (switch) end...when it contacts the plastic disc obstruction in the body tube, hold the tube tightly, and whack the rod with a hammer...HARD! When you dislodge the black plastic disc with the little brass colored rivet in its center, THROW IT AWAY! It serves no purpose, and stops the flashlight from working. Once removed, reassemble the head-end, re-insert the battery, and twist the switch cap back on...it should work fine now. Those caps were supposed to ensure the battery was inserted the correct way...the rivet is slightly indented on the tube side, and slightly proud on the head side. This would stop the flat negative side of the battery from making contact with the L E D driver circuit and destroying it due to reverse polarity...BUT...most 18650 battery positive end tips DO NOT fit the recess in the disc, so it prevents the flashlight from working AT ALL!! I have bought 12 of these lights...had to "modify" all of them. I carry two on me at all times, I have several in my vehicles, and have given some as gifts. In 5 years, the ONLY problem I've ever had was the initial need to modify the lights. Other than that, they are blindingly bright, highly reliable, light weight, and hold a charge regardless of the temperature of the vehicle they are stored in for months at a time. Good luck, and let me know how you made out!

Have you tried replacing the batteries first? If replacing the batteries does not work contact the manufacturer or seller for more help. I have had good luck with this flashlight and just bought another.

I just put the batteries in my lantern a few days ago. It seems to me when the light is off and you push the button it comes on on high , click the button again right away and it goes to low. If you leave it on high and then push the button it will start to flash.P

Make sure Batt in right. Take batt pack push up against light (should work). Need to add shim to bottom of batt pack(I used bleach bottle plastic) When you get the right thickness. glue this to the bottom of batt.pack. PS. Take my light apart and store in a sock to cut down on Corroson and possible moisture.

Unscrew the small end. you will have to test it to see which way the batteries have to be turned but if you try both ways and you still have no light the bulb may be bad. Mine worked fine.

I believe you are talking about surefire it is not a surefire light it is a trustfire. These lights are super bright but you must buy some quality batteries. One dead battery out of the three will cause the light to not not turn on. These lights require 3 18650 lithium batteries. These batteries can be bought on amazon however better quality batteries can be purchased at fry's electronics.

I have a couple running on 6px tactical lights, although I couldn't get them to work on some other similar sized model Surefires. I also have one running on an incandescent cheap nextorch light.

Purchase either EverReady or Duracell alkaline batteries [D]. If you use these batteries and they ever leak, you can send the flashlight back to MagLite and they will repair or replace it for free. I recently had to replace my 12 year old 3 cell MagLite, because I used cheapo batteries, and of course, they leaked and ruined the flashlight. It was the only time I didn't use EverReady. :-(

My suggestion is to wrap some electrical tape around the batteries you might not be getting good contact since the batteries diameter is slightly smaller then the body of the flash light. I encountered this when I bought mine and no problem since

Make sure your batteries are correctly installed and then plug it into the provided charger. I charged mine when I received it. Also check all battery compartment connections. I had a slightly bent connector. If it fails to work after that I would defiantly as to exchange it. They really are great headlamps. Despite some of the minor issues.

A couple of the flashlights didn't work in my package too. I shook them up a bit and wiggled the battery and some responded to this. I didn't have the issue of any hot lights though.

I'm sure that is not usual. However, looking at previous answers they are all over the place. On my RavPower 6000mAh you simply hold the botton down for 4 seconds and the flashlight lights. If you just got the unit I would recommend returning it or calling RavPower customer service.

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.

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!
