Replacement Cubes for Cozmo

While many of you have come to know and love Cozmo over the years, it is possible that you may be in need of a new set of replacement cubes. Over time the cubes may have become damaged in any number of ways, or even lost.

Unfortunately, Cozmo replacement cubes have been hard to come by, and the only place I’ve seen them available was on Amazon, through the Anki Store. That is, at least until the recent release of Cozmo 2.0.

Now that Digital Dream Labs has re-released the friendly little robot pal, as well as a new and improved Vector 2.0, they are also providing replacement Cozmo cubes which are sold individually. 

Cozmo cubes for sale are available, and compatible with Cozmo 2.0, as well as the Classic Cozmo and the limited editions versions.

How to replace the Cozmo cube battery

Replacing the Cozmo cube battery is quite simple, and only requires two things.
First, you need a #2 Phillips head screwdriver, the “cross head” one.
Secondly, you need at least one new E90 Alkaline battery, 1.5 volt, size LR1 N. (each cube requires one battery)
And last, but certainly not least, you need to have a proper way of disposing of the used batteries. 

  1. Remove the cube cover by unscrewing the single screw and open the cube.
  2. Remove, and set aside the used battery and prepare it for proper and safe disposal. 
  3. Replace the dead battery with one, new Alkaline N / E90 / LR1 1.5 Volt battery (Positive end up)
  4. Replace the cube cover and screw the Phillips screw down. (do not over screw, as you will cause damage to the cube)

Cozmo cubes not working with new batteries?


  • If for some reason one or more of your Cozmo cubes is causing you trouble, you should start by checking the cube battery. Follow the instructions above to replace the battery. 
  • Occasionally a cube will need to be reset. Similar to the instructions above you will need to remove the cube cover and wait for 10 seconds for the cube to reset. Close and screw the cube coverban on and you see the cube false Red > Green > Blue, this indicates that the battery is fine.  
  • Make sure Cozmo is near the cube when replacing the battery or resetting the cube. 
  • Finally, you may need to check if the Cozmo cubes are synced. Go to “settings > cube status”. When properly connected you will see a green check indicating a successful sync. If Cozmo and the cube are not synced properly, you will see the “not connected” status. To fix this, click on “auto connect to cube” and Cozmo will search and re-sync with the cube. It’s important to do this, especially after the cube has been reset, or the batteries have been replaced.
