Is it safe to use lithium AAs on Fenix and Stream Light?.....

[mega_lumens]

I wnat to buy lithiums AA and AAAs for my Fenix L1p, E0 and Stream Light 4AA Luxan. I want to stock up on lithiums for emergency situations. Is it safe to use lithiums in the above mentioned lights?

What other lights accept AA or AAA lithiums together with regular alkalines?

Thanks

The Fenix and the Streamlight (Propoly?) Luxeon should be fine with lithiums. The lithiums you have to watch out for are the 3.7 (actually 2.7-4.2 depending on stage of charge) 14500 (AA size) and 10440(AAA size) rechargeable lithiums. Many lights accept lithiums, it's the direct drive lights that you have to worry about.

I think there was a list of lights that will accept lithums somewhere in this sea of information. I think all of the newer Cree and Seoul lights all accept lithums, and most of the greater then $25 can also accept the 3.7V rechargeable lithums.

Fenix L1P is great with lithiums, it's noticably brighter than with an alkaline. Do some searching through the archive, this has been discussed plenty last year.

The Fenixes work well with lithiums

My L1P didn't work with the 14500.

Mega_lumens, do you mean the lithiums as mentioned above (e.g. 14500s) or the 1.5 volt Energizer Ultimate Lithium AAs. If you mean the latter, then yes, absolutely no problem. I've been using the Energizers in my LED Lenser for nearly a year now, no problems.

THe Fenix L1P cannot handle 3.7 V... Neither can the L1S.

THe ones that can handle 14500 (with no medium/low modes): L1/2T, L1/2D, L2P, L2S

The Fenix's will work fine with lithium AA/AAAs. I've heard of people using 3 lithum AAs plus a dummy cell in the SL 4AA PP. Fresh, a lithium AA is 1.6v pushing 1.7v. The PP's excellent regulation circuitry will easily keep up with only using 3 cells (voltage of 3 fresh lithiums isn't much different than 4 half-used NiMHs or alkalines). I don't think 4 lithiums will toast the PP, but you should probably keep an eye (or hand) on heat.

Let's be clear that we are talking about LITHIUM (as in Energizer e2) and not LITHIUM ION (rechargeable cells like AW's) unless further corrected by the original poster.

If we're talking about LITHIUM (as in Energizer e2, as in primary, non-rechargeable, 1.5 volt rated, sometimes called L91 in AA size and L92 in AAA size) then I ask: are there ANY lights that won't take these Lithiums? Fresh out of the package,their voltage is only slightly higher than a fresh alkaline.

I would guess the OP was asking about lithium primary batteries of the 1.5VDC variety. From the tone of his post, I believe he was looking for the long shelf life.

However, the OP has not logged back on since that post, so we may never know for sure...

Ditto- I ran lithium in my L1P for 1 1/2 yrs b4 I sold it to my bud.- still going strong.

No, there are not any. Any light that will run on alkalines, will run on 1.5 - 1.7 volt Energizer e2 lithium batteries.

Some lights won't work with lithiums because lithiums and most rechargeable batteries have a lower internal resistance then alkaline batteries. They also have less of a voltage sag then alkaline batteries. Some flashlights require the internal resistance of an alkaline to keep the power within spec so internal components won't be damaged. Some of the cheap multi LED lights will turn angry blue when used with lithium or rechargeable batteries but work fine with alkaline batteries.

Yeah, pretty much what I was thinking. The only thing I could imagine that might be a problem (hypothetically) is a cheap semi-regulated light with poor heat management that relies on the alky to sag under load - the Lith in this case would supply significantly more energy and maybe overcook something.

Ah-HA! Gunner12 posted while I was typing my response above. He mentions a real-world situation which I called hypothetical. Maybe a better answer for the OP is to stay away from cheap lights.

 

[mega_lumens]

Sorry I couldn't respond faster earlier.

Yes I did mean primary non rechargeable 1.5 lithiums like the Energizer ones. Thanks for everyone's answer; now I know that it is safe to use the primary 1.5 lithiums with my lights.

The Streamlight Survivor is one light that is not compatible with Lithium (L91) batteries. At least the company says so. It's stated in the instruction pamphlet. Here's a link to a post of mine on the subject a few months back. http://candlepowerforums.com/vb/showpost.php?p=1635212&postcount=4

Maybe they were just waiting for a decent battery and it's actually a happy blue
