Review: Works for Cozmo the robot - This was perfect for my son’s little robot Cozmo. We got Cozmo off of eBay. The battery worked, but it would only hold a charge for about 20 minutes. That’s why I got him this one. This battery lasts for a very long time. The robot never goes dead.
Review: Does what it says - Used one of these batteries to replace the battery in a ANKI Cosmo. The repair wasn't easy, but the battery worked exactly as I hoped, brought Cosmo back from the dead.

### ⭐⭐⭐⭐⭐ Works for my Anki Vector
*by E***V on September 6, 2024*

This battery doesn't have exact form factor the Vector's original battery has, but still it fits just well and it works fine. Vector is roaming my table right now being connected to my local server (WirePod) and communicates with me just fine. I'm happy!
