JetBeam Jet II PRO Batteries

I’ve just received one of the above … what a great little light!!!

I happened to have one unnamed 16340 button top battery that came with another torch and that works fine but wanted to return that one to the original torch and have a couple of spares.

The button tops though are harder to find does anyone know if these run on flat tops as well … was going to pick up some efest ones if so???

AWT 16340

These are great batteries
