Introduction: Bubba Gump Battery Swap

I happen to like going to Bubba Gump, and while their food is pretty alright, I mainly go there for the cocktails! One of the treats of going there is that, for a lot of the cocktails, you get to keep the glass. I'd love to get one each of all the big, glass ones, but I also like the plastic light-up ones as they are absolutely smashing if you're having a garden party - they look great.

After a certain amount of use the batteries do eventually die, and having had this happen recently I thought I'd document the process of replacing them.

You'll need 3x AG13 button cells per cup.

Step 1: Unscrew the Base and Remove

If you take a look at the bottom of the cup you'll see 3 Phillips type screws. Unscrew these and set them aside carefully.

Once you've removed the screws, locate the tab on the bottom (see photo) and use this to pull the two sections apart.

Step 2: Take Off the Reflector and Separate the Circuit Board

You should be able to carefully remove the reflective sheet, noting the orientation (it helps that the LEDs aren't equally spaced).

Once this is off you'll notice another Phillips screw holding the circuit board onto the bottom of the cup. Remove this screw and pop the circuit board out.

Step 3: Open the Battery Tabs and Replace

Flip the circuit board to see the batteries. There's a little tab on the outside of each battery holder keeping them in place. I used the edge on my Phillips screwdriver to bend these up slightly, enough to push the batteries out with a skewer. Note that positive on the battery is facing away from the circuit board.

Replace each battery and bend the retainer back into position.

Step 4: Reverse the Process and Screw It All Back Together

Time to put it back together.

Take the smaller screw and use it to connect the circuit board to the base of the cup. Make sure to let the switches through the base (the long, springy one goes through the bare hole, the other goes into the silicone).

Push the reflector back onto the circuit board, under the LEDs.

Align the base with the cup, letting the tab drop into position.

Screw the base on.

Push the button.

Have a drink!

I have one of these cups, and I want to replace the batteries. I've unscrewed two of the screws, but the third one won't come out. It's fully unscrewed, but it doesn't come out. I've tried shaking it, but it doesn't work. What should I do?
