What should I do when the cube battery for Anki Vector or Cozmo dies? Kinvert will show you how to replace the battery in your Vector/Cozmo cube.
Kinvert has changed just about the most Cozmo cube batteries of anyone short of Anki. We teach kids many STEM topics including Robotics and Coding with Cozmo.

Cozmo and Vector’s Cube Battery
How do I find a replacement cube battery for Vector and Cozmo?
First, let’s talk about the Cozmo cube battery size (which is the same size as the Vector cube battery). A lot of batteries have a size of AA or AAA for example.
Cozmo and Vector’s cube battery is a size E90, LR1, or N size. All 3 are essentially the same size. I don’t know why it has 3 names.
Here are some batteries we have used and we know they fit.

Most of you won’t need a huge quantity. If you teach like us you might want to buy in bulk. We went through a ton of batteries in our Cozmo Robotics Competition.
You just need a phillips screwdriver. There is a tiny chance you need a flathead screwdriver as well if you need to pry anything.
How to Replace Anki Vector and Cozmo’s Battery
If you look at the bottom of the cube, you’ll see a phillips head screw. Take that out. Remember “righty tighty, lefty loosy.”
The bottom of the cube should come off. If it doesn’t come off easily, you can pry it gently with the flathead screwdriver.
Make sure to take note of which end of the battery goes in to the cube.
Take out the old battery and properly recycle it. Put the new battery in the same orientation as the old cube battery.
Put the bottom lid of the cube back on, and gently screw in the phillips head screw. When you put the lid on and start closing it, you should see the cube lights flash.
That’s about it. I know this was a short one. That’s because the process is that easy.
Kinvert has around 20 Cozmo robots that we use to teach with. We have classes that include Robotics for Kids and Teens, as well as Coding for Kids and Teens. So we have changed a lot of cube batteries.
When a student was replacing a Cozmo cube battery, the captive nut broke out and now rattles around in the cube. So we don’t have a good way to fasten the lid back on.
We used clear tape to hold it shut, and that works.
Other than that, we’ve never had a problem replacing the battery in a Cozmo or Vector cube.
We’ve even had students change the cube battery easily.
Just make sure you don’t torque it down too hard.
You Might Also Be Interested In…
If you’re here reading about Cozmo and Vector batteries, chances are you might be interested in a few other things we do here at Kinvert.
My first recommendation is to read our articles on the Anki Cozmo SDK and the Anki Vector SDK. These talk about how you can program your lovable robot in Python, which is easy to learn and is the top language of choice for AI, Machine Learning, and Data Scientists.
If a fully written language seems daunting, check out What is Robotics and Kinvert’s Ultimate Guide to Block Coding. If you have a Cozmo you can program him with code blocks that are sort of like Lego bricks. It’s a great way to get introduced to coding, which is an incredibly important skill.
Finally, this is one of the things we emailed out to our Cozmo and Vector mailing list. If you want to get other useful information like this, please fill out this form. You can unsubscribe at any time! We had spam as much as you do.
