can this take a rechargeable CR123 battery? I know it doesn't take the 18650

i am using the RCR123A 3.0v battery from Tenergy. they came with a charger when i bought the batteries. they work fine. heads up though, when the batteries start to get low it does not get dim, it just stops working, so pick up a set of extra batteries.Other than that very powerful light, and very durable.

Yes again; I have been using rechargeable CR123's for a year now, with daily use, without incident.

No, you can use either a lithium rechargeable 18650 battery or the old-skool 2 cr123a's. the single battery is a superior and cost effective option. It has a killer runtime and 12.4 watt hours capacity-about the same as four rechargeable AA's. CR123 is a thing of the past with the awesome new lithiums.

I have several 18650 batteries. They are all the red UltraFire batteries, but I'm sure they would be the same size as yours. The single red UltraFire 18650 battery is too long and too narrow for this flashlight. At least the "AAA" batteries it takes are easy to find.

Good Morning, I am scared to say that it will take any battery but as long as its a quality 18650 you should be safe. I just checked to be sure and dropped a few different style 18650's into the bore and all worked. The light comes with the Fenix ARB-L1t 3400 + I am tossing in 2 Xtar CR123a's. Thanks, Shane

It will charge any AA or AAA rechargeable battery. I don't know what 18650 batteries are

CR123A are what I have in mine. So long as they output 3V and are the same size as the stock batteries, you are good to go. SF123 (Surefire brand) and others will work fine. CR123A will give you a lot of bang for the buck.

it comes with two CR123A batteries, you can choose two CR123A batteries or one Rechargeable 18650 battery. thanks.

As long as they take the 18650 they will. I am very happy with mine. They last 5 times longer then cr123's best buy for me. Make sure you get the green Panasonic batteries with it, good luck, scoobydenon...

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.

Yes, one of these will replace two CR123A batteries, either the rechargeable or the non recharable types, just make sure your device has a protruding tip for both positive and negative sides of the battery since the connection terminals on the NCR18650B version batteries are flush with the body, they are not button top and if you dont have a spring type contact at both sides they will not make contact.

this wight did not come with an 18650 it came with 2 cr123 and i purchased a Nitecore Rechargeable 18650 and it works great.

William, your question doesn't exactly make sense. The Super TAC X does use standard CR123a batteries. Standard CR123's are not rechargeable. However there are companies out there that do make rechargeable CR123a batteries listed as (RCR123a). Just do a search for rechargeable cr123a and you will find plenty of the batteries and their chargers. No reason they shouldn't work in this light unless they have a nominal dimension that is a tad wider making them a tight fit.

No in the PC20 You really can really only use CR123 or RCR123 batteries. The diameter of the 18650 is too big.

I had to Google 18650 battery to see how big it was but it looks like it's about the same diameter as a cr123 and about 1.5x the length so I would think it would fit one 18650

The 18650 battery will work. Its designed to use 18650. However, not sure if quality 18650 batteries come in 4000mah.

no, you must use the 18650, you can also use 2- 123cr batteries, but i would stay with the 18650.

No, they are not the same battery. The 18650 is a rechargeable lithium ion battery. The cost is reasonable and, having used about 8 of this type battery, I can vouch for their longevity and utility.
