Will this work with one 18650 battery in place of the two cr123's like most flashlights will?

I don't know, but because it needs the 4 contacts, I would recommend that you use the cr123's.

No a 18650 is twice the length of a CR123A and if you install it the battery won't even close

The CR123's are brighter but you will spend a fair amount of money vs the rechargeable 18650's. One more tip, the 18650's will fit perfectly in one of those survival match tube's. Great for carrying a spare battery. This will be your favorite flashlight.

No, the 18650 is both slightly longer than two CR-123a's and larger in diameter. Also, they run 3.3-4.2V as opposed to 5.6-6.4V total for two 123a's - the LED flashlight must be designed to accommodate them. Many two '123a cell lights made in the PRC, like my Olight M21 & M22 and Fenix PD-35, will use them - and work better, too. None of my 2-cell US-made Surefires will fit them - the body tube's ID is too small.

Can't be. An 18650 is WAY bigger than a CR123A and has 2-3,000 mAh. In a word...unpossible.

No, this flashlight can not use rechargeable batteries. Only standard non-rechargeable CR123A batteries are recommended by Foursevens. It does come with one CR123A battery though.

You can use 3 AAA, but need to buy an adapter. Search for "18650 adapter aaa"

The correct battery is the 18650. You could also use two CR-123 batteries instead. Either will do the job.

I'm not totally sure but if the four 123er's are in line then two 18650 in line should work. I would test and check to see that they are not overheating. Try searching on Google too.

Yes. This flashlight uses both batteries in series and has a very bright light. Great flash light. If you are buying it as a gift buy two and treat yourself too.

No batteries come with this light. Cr123 can be bought at a lot of stores. 18650 are rechargables, will need charger.

Yes, according to my manufacturer, an 18650 Lithium-ion battery will work in this light. Thank you for your question and your purchase. Have a great day!Don R.

No, for 2 reasons: the CR123a are too big around to fit in the battery compartment and 2 CR123a together are too much voltage for the LED. You can fit 2 of the CR2's, but they are also too much voltage for the LED. I use AA rechargeables and 14500 batteries and they work fine. I hope this helps and have a good day.

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?

I used these batteries in my flashlight that called for the cr-123a batteries and they worked fine - saw no unusual issues (ie. shorter life, uneven lighting, heat, etc. . . ).

I would guess that it will work if you are able to charge the battery. The flashlights have a spring to push the batteries together. If it a small difference the spring should be able to compensate. Good luck.
