3v Rechargeable batteries

Aloha!  I have a flashlight that uses 2 - 3v 123a lithium batteries and want to be able to use rechargeable batteries.  Here is what I have been looking at:

Has anyone ever used these batteries?  Chargers?

What do you guys think?

I was actually wondering the same thing a few weeks ago.  Unfortunately, all the 3.0V rechargeables I've found have a peak charged voltage of 3.6V.  I understand this is no load voltage and it'll sag back down under draw, but in a 2xCR123A situation 7.2V on turn on is worrisome.  

I don't know about Surefire, but Inova's CS told me it would destroy their stuff.

It is for a surefire a2 led aviator that my nephew gifted me when he found out I was into flashlights.  He's in the military and they are provided surefires for weapons and general use.

Hi fishinfool!

Don't know anything about 3.0V rechargeables but could you tell your nephew that I'm into flashlights too? 0:) Wink

Best course of action is to ring up Surefire's Customer Service line and ask.  I'm not generally a fan of Surefires because of the cost, but it would suck badly to poof a light that expensive because you used the wrong batteries.  If the 2x CR123a rechargeables don't work, you could always try a 17670 instead.

Ah, the A2... I don't think so. Lets see... dredge up some old info.... as I recall, most RCR cells don't fit into the A2 body. Not sure if thats changed with the A2L, but I don't think so. The 5mm's are already heavily overdriven on 2xCR123. 2xRCR123, at 3.6v, would requiring upgrading the SM resistors on the 5 mm ring, and possibly adding a resistor to the main LED.

Looking at the fine print, the first batteries are voltage regulated; so, most likely low capacity, and low durability. 

We do not recommend this setup for any SureFire flashlights, or other brands of incandescent (halogen, kyrton, xenon, etc) flashlights which have a bulb rated 7.2V and under. We typically do NOT recommend these for any bulb flashlights - use them at your own risk in these types of devices. Despite the voltage regulation at it takes the voltage regulation ~12 milliseconds to activate. They work GREAT for most LED flashlights!

 

The second ones are Lifopo4, so charge to 3.6 volts. Would require mod described above.

Thanks guys.  I really don't use it much anyway because I'd rather use my cheapy lights that are brighter and are a lot cheaper to replace if accidentally broken.  I’ll just put it back in its box and use it as a permanent dust collector.

But seriously, they go for 145-160 like new on CPF marketplace.

You can also use cheap CR123 from DX, they are around 0.80 each one.

I think my nephew paid over 200 bucks for it and don't get me wrong, it is a very, very nice light but for $200 I would expect something that pumps out at least 1k lumens or something pretty close to it.  I also like that it's a dual output light (red and regular white but only 120 lumens) and it is very, very well made but for 200+ bucks--it better be.  I also don't like the UI or that it only uses non-rechargeable 3v 123a's.   

Another thing I like about Surefire is their customer service.  I broke the pocket clip some time ago and 2 days ago, just for the halibut (helluvit), I sent them an email asking where I can purchase a replacement clip and they replied with "Send us your home address and well send you one free of charge".  Not too shabby right?

I'd say opps I lost it for a fenix 35  or a 45 ..

Maybe i'd just say i lost it to get a second one to sell  and get both:X

Many of the CPF people don't care about the amount of light output-and the UI is considered by many to be the best ever (I might prefer the McGizmo PD, but YMMV).

And for the love of god, don't buy DX primaries. batteryjunction's cells are on par with Surefire and duracell, and cost a buck apiece.
