I made this little base for making small campfires for tabletop war gaming. Remove the LED & 2032 battery from a dollar store flickering tea light & install them into the base. The positive lead will run through the side channel & be bet to grip the side of the battery. The negative lead will need to be trimmed shorter & curled up in the middle as shown in the picture. The battery is friction fit. If it's hard to install, just trim the edge of the battery opening a bit. I added a second one with sloping sides.
