Is there a higher output AAA battery similar to the 14500 AA? (Quark Mini)

I know some people have been using the 14500 AA batteries in the Quark AA mini's in order to achieve 2x lumen outputs. Is there a similar option for AAA lights, such as the Preon 1's?

I think you are asking about the 10440. It's a Lithium ion 3.7 AAA size. You have to be careful of heat build-up unless the light supports it like the Eiger or Liteflux.

For safe operation of Li-ion batteries current should be below 2C or the current number should not be 2X above the capacity number.
14500 700 mAH > max safe current 1400 mA
10440 350 mAH > max safe current 700 mA
-
The SSC-P4, XRE, XPE, XPG will run at ~1400 mA when direct driven.
With a 14500 you are at the maximum safe current allowed.
With a 10440 you are at double the maximum safe current allowed.
-
The Liteflux circuit will keep the current at safe levels - 350 mA with AAA, 700 mA with 10440 but to your eyes only 1.4X as bright.
-
With a Preon 1 the circuit shuts down and you enter the danger zone of the exploding battery. 350 mA with AAA, 1400 mA with 10440.
We have not heard of any Preon/10440 explosions because CPF members who run that combination know the danger and normally only use low and medium modes. High is reserved for emergencies and only used in short bursts.
-
Normally a Preon 1 gets 70 lumens on high.
Here is some information on what a 10440 can achieve in a Preon:

Just want to add that, unlike the 14500 the RCR123 li-ion batteries, which can be had with PCB protection, their cousin the 10440, is not protected because of the small size. So be careful about charging above about 4.2v and discharging below 3.6v. Overcharging (so it is written here) can cause , while undercharging can cause :fail:.

Also, several AAA lights, e.g. the itP A3 EOS, the Fenix LD10, and the Maratac AAA can use the 10440 on high for shorter periods of time--several minutes. I use the itP that way and used to use the original LD01 too.
