Cozmo has an internal Lithium-ion battery that is charged using the included charging dock connected to a powered USB outlet. Typical charging times for Cozmo are approximately 30 minutes, and will vary based upon the USB power source that you use. When fully charged, that allows Cozmo to play for approximately 90 minutes. Actual playtime will vary based upon how you use Cozmo. Cozmo's internal battery is not user serviceable, but is covered by Anki's Limited Warranty.
Cozmo's three Power Cubes use a 1.5 Volt / N size battery, also referred to as an E90 or LR1. Batteries come pre-installed in Cozmo's Power Cubes and have a plastic pull-tab to prevent these batteries from draining during shipment. As soon as a pull-tab is removed, the Power Cube's batteries start loosing their charge. Approximate battery life for each N size battery is 20-40 hours of game play. Depending on how you play with Cozmo, the batteries may not drain equally, so don't be surprised if you may have to change one battery before the others. Power Cube batteries are user serviceable with just a #1 Philips head screwdriver. Please note, that Power Cube batteries are considered disposables and are not covered by Anki's Limited Warranty.
IMPORTANT NOTE: Only use Alkaline N (1.5v E90 or LR1) batteries in Cozmo's Power Cubes.
Do not use A23 batteries in the Power Cube - using an A23 battery will damage the Power Cube beyond repair!
