Can I use a 18650 Li ion 4.2 volt 4200 mAh in a 1000 lumen Cree Xm -l T6 led flashlight. Will it damage the flashlight?

I would think it would overpower it and make it overheat. That's a better question for the manufacturer. Wouldn't want to give you the wrong advice. Sorry that wasn't much help!!!

where in the world did you find an 18650 rated at 4.2 volts,ive never seen those

I'm not sure if it will damage it or not. I try to match the battery that came with the flashlight. Then I am positive it will be the correct battery and it won't damage it.

It should work, I've used these in D-cell flashlights before and it's worked just fine.

No, The ones with the XML-T6 LED's only work with the 18650 battery. The ones you mention that work with AA look similar to this one but are small and use the Q5 LED just look for what type of LED it used as there are multiple brands of each. The AA version's are cheaper and great to stock up on. Good luck

Not sure about damage, but my flashlight (FENIX) worked with those, but company recommended TENERGY 18650 rechargeable. One 18650 same size as two CR123s. TENERGYs hold charge longer. Should work for you, John, but email to your LEGACY company should confirm it for you.

There is a performance gain by using the 18650 battery. I tried both battery options and found the 18650 to work the best. I have a couple other flashlights that uses the 18650's. I purchased a 12pk of the 6000mAh batteries and that is my recommendation. That last for ever. I hope this helps.

With all due respect, if you do not know what a 18650 battery is, you should probably look for another flashlight that uses AA or AAA. There are a lot of possible dangers associated with this type of battery if you do not fully understand it. There is a 4 dollar flashlight on Amazon similar to this that uses a single AA battery (search for "cree flashlight" - FordEx Group is a popular one).

AAA batteries will die much quicker than a 3600mAh 18650 battery so yes you will get brighter light for longer from an 18650. There are several advantages of the lithium-ion. They are all we use.1. They maintain a brighter beam for a longer time.2. You can quickly swap a fully charged battery to keep your light operational.3. You aren't constantly throwing away AAA batteries.

They will not damage your flashlight. I use the exact batteries in my New Intova Nova LED Scuba Diving Light. They will charge quickly and I can get two dives per charge or several surface dives looking into holes and caves. The charger seems to work fairly well too. I have been using the charger and batteries for around six months here in Hawaii.

No, 18650 battery is too big for it. The flashlight is Powered by: 1 x AA / 1 x 14500 3.6v Battery (NOT Included) as advertised. If you need 14500 battery, please search B00FYMPSGA.

All my flashlights only uses two cr123's but if yours uses 4 theoretically you should be able to stack them as most flashlights that are cr123 are designed to run 18650's as well. Good luck.

i just looked that flashlight up on amazon and it said it takes 2-cr123a or 1-... 18650 and that is the battery you are asking about ...so yes you can use that battery

Per Don R. "according to the manufacturer, and 18650 Lithium-ion battery will work with this light." Is your rechargeable battery attached with a USB port? If it is, contact the seller and request their help. They may sell or send you an extension piece to your flashlight and that will enable the use of the USB rechargeable battery. As previously noted this Seller has Excellent customer service and will personally respond to your request.

depends on your flashlight. does it have an actual bulb or an LED? these batteries are safe for every cr123 LED flashlight that i have ever owned. if your flashlight has a high pressure xenon bulb or similar then you need to check the specs. dont bother with charging voltage, you are looking at discharge voltage. what kind of flashlight do you own?

18650 is 4mm thicker, and 15mm longer than AA according to what I read. There does not appear to be any extra space in the flashlight battery compartment. I would say no. The 18650 will not fit.

mAh is a measurement length of charge and really hss nothing to do with voltage. What it does mean is that the charge will power your flashlight for a longer length of time on a single charge. They are still only 3.7 volts so they wll not harm uour flashlight. Worth Trust batteries have over voltage and short protection circuitry in them which makes them bad to use for a vape cigarrete but they should work fine for your flashlight.

No. LED flashlights that advertise as being able to use 18650 and AA use a adapter to bring the AA up to the larger 18650 size.

If you gave a specific model for the flashlight, I'm sure we could answer this question better. The answer, given the limited information given, is "maybe". There are a couple things to consider. First, CR123s are narrower than 18650. CR123 are 17mm wide (diameter), and 18650s are usually a little over 18mm wide (diameter). So a light that is sized exactly for CR123 will NOT fit 18650. Many lights are sized large enough to accommodate both types, though, so it MIGHT work. The second consideration is voltage. CR123s are 3V, and they maintain that voltage right up until they are almost dead. 4 CR123, then, will deliver 12V for the whole of the battery life (not exactly, but close enough for our purposes.) Two 18650s will deliver only 8.4V, even when fully charged and under light load. If you ask for high current, the voltage will sag even more. And as lithium ion rechargeables are used, the voltage declines. At 50% capacity, they will be down to somewhere between 3.6-3.7 volts each, or 7.2-7.4 volts total. The question is, then, can the driver in the light compensate for the lower voltage of the 18650s, or not? Some lights can, and others can't, but without knowing the exact light you have, there is no way to be sure.
