What on earth would a AA size Li-ion be for?

[conanthewarrior]

Hello everyone, as you know I am just getting back into vaping, and have found something that has me really puzzled.

I found a Efest purple wrapped battery, nothing unusual right? Well it is AA sized.

I can not for the life of me think of a device I own that would use a AA sized Li-ion, everything I use AA's for I use eneloop rechargeable batteries, plus there is the voltage difference with the Li-ion being much higher than a standard AA or rechargeable.

Can anyone think of anything vaping related that would use this? As it is doing my head in Haha

1 li ion AA size and 2 blank AA in place of 3 AA, if it is 3.7v
there are 1.5v li ion AA size available (have built in buck converter to drop voltage) which as far as I know is most popular.

There was a mod that took aa's a few years ago but it never seemed to take off

Thank you all for your replies, but I figured it out- I found a standalone coil resistance tester that you screw your RDA/RTA into, and it had one of these batteries in.

For some reason it needs the 3.7V Li-ion battery instead of a standard AA 1.5V.

Do you mean a 14500 battery?
I've got loads of them here, mostly used in torches but I also have a Nemesis mini mech mod that uses them. A bit pointless really, as the amp limit restricts you from using a coil under about 1.5 ohms from what I remember.
