How long will this flashlight work on a fully charged battery
887806
I have not measured it but I am guessing around 45 minutes or so. It gets pretty warm, and is very intense. On low setting it will last longer.

mine worked about 3 minutes then started blinking on and off as I would move it about and shake it - since it quit working reliably, and wasn't as described, I didn't want to chance a fire from a cheap lithium product - so I threw it away and ordered a Streamlight. I think it's better to cut your losses and just get a quality product.

The tradeoff for super bright output is lessened run time...On a full charge, and if use continously you get less than an hour and the unit gets pretty warm...I always keep a spare battery with my if I amusing on project survey or such...

I don't know for sure as I have never run it until it quit. My best guess is that it will light up for 4+ hours.

My unscientific way on checking battery life was to just turn it on and let in shine. There is no high/low switch, just slide the barrel back and forth to make the magnifying lens intensify the light beam. With this in mind, I had my flashlight turn on for more than 10 hours and the was still useable light coming out. Hope this helps. Oh by the way, it had a full battery charge at the beginning. I am using the ultra fire BRC18650 3000mAh 3.7 volt li-ion battery that came with my flashlight kit with the included charger. Other people have done a more through test on these batteries. Like I said above, my study is more anecdotal not scientific.

A full charge in direct sunlight takes 8 hours. Flashlight mode lasts for about 2.5 hours. Lantern mode lasts for about 1.5 hours. Emergency mode lasts for about 8 hours.

I purchased 2 of these for bugout bags so I have never fully charged them but I can tell you this, I wound it up for about five seconds four months ago and if I push the button, it still lights up.Hope that helps.

I still have original batteries that came with the flashlight in mine from a year ago. Don't use a whole lot though. I have problems with it wanting to go off and have to shake to get it to come back on. It does have a lifetime warranty though. You can use rechargable batteries in it.

I don't know, but my TrustFire TR 9T6 flashlight has turned out to be a piece of crap. 6 months after I had it, 3 of the 9 LED's stopped working, and after about 30 seconds of being on, the remaining 6 LED's start to flicker and the light fairly quickly gets very dim. Like the batteries had failed. But if you wait a minute or so, then turn it back on, its nice and bright again and doesn't flicker-----for 30 seconds----then it repeats the process.I have UltraFire NCR 26650 batteries.

the item requires 18650 batteries, after the batteries is fully charged, it could run about 1 hour for the Strong Brightness model.

I have no idea how long it will last. I will tell you this though, I once used my flashlight to plug some cables into a computer under my desk that had poor lighting on a Friday. I completely forgot about it over the weekend and walked into my office that Sunday and noticed my flashlight was still on. It still seemed as bright as ever. I still haven't changed the batteries in over a year since that incidenet.

I'm not sure as I am still using the same batteries I installed in December. Note though the flashlight is not used 8 hours a day, 7 days a week. Hope this helps.

I'm not sure. I used it around the property on appx 15 mins I never noticed. it is a amazing flashlight !!! just be sure to turn it on at least once a week for a minute or so, son in law left his in a pack unused for a couple of months and the batteries swelled up and could not remove them. Mine is great though.

Burn time on a full charge battery is about 2-3 hours if set in the on setting. Having said that, with the light set in the motion setting it will last the night. It also depends on how long you have the motion timer set for. I don't know how many lumens it puts out but I have one set up to light up my full size pick up and it is quite bright and covers the entire truck.

The manufacturer, Streetwise, recommends 8-12 hours of charging. It should be working by now. If not, the manufacturer offers a lifetime warranty. However, make certain it is not user error. If it turns out to be user error, they will charge a restocking fee and they will not pay any of the shipping. It will have a master switch on the tail end - near the charging port. Make sure that is turned on. Then, check the flashlight/stun gun switch. All the way back is off. The center position should turn on the flashlight. The forward position puts it in stun gun mode, then you'll need to push the stun gun activation button. Once you can be completely certain it isn't working, then make arrangements to return it for a warranty replacement.

Not at all. In fact its better to run the flashlight down completely and then have it re-charged. The battery will keep a stronger and longer life when you do this. This is one of the best flashlights that I have ever owned and make great long term gifts that you will have for years to come. After buying the cheap flashlights and all the batteries throughout the years you will purchase more throughout the years. I work in the Law Enforcement line of work and it is a must for department equipment along with Fire Departments. You will be happily pleased with this piece of equipment. IT'S G R E A T !!!

I have to say that I don't know precisely. My experience with battery lights this bright is that the burn time at full power will not be long, something less than an hour. I have had it going full for possibly 30 minutes without a decrease that I noticed.

Recharging time depends on how long you use the flashlight. I used mine for 4 or 5 hours doing an inspection-one morning, turning the light off and on during that period of time. When I got back to my office I put it in the charger and had lunch and did a few errands. In a couple of hours I went out and did another inspection and the flashlight was fine. Always leave the flashlight in the charger. Don't worry about overcharging. It will not overcharge.

Both of the ones that I purchased stopped taking a charge after 5 months of use. I used them as emergency power for cell phones . The flashlight would work about 6 hrs before the charging issues
