Cozmo has an internal lithium-ion battery that is charged using his charging dock and connected to the included wall adapter. The wall adapter supports 110-220v. It takes about 10-12 minutes to fully charge Cozmo, and this allows for 1-2 hours of play time. Cozmo's internal battery is not user serviceable.
Cozmo's three Power Cubes use a 1.5 Volt / N size battery, also referred to as E90 or LR1. The batteries are pre-installed in the Power Cubes with a plastic pull-tab to prevent the batteries from draining during shipment. As soon as the pull-tab is removed, the batteries start loosing their charge. They are secured by 1 Philips head screw, and can be changed by the user. Approximate battery life for each N size battery is 20-40 hours of game play. Depending on game play, the batteries may not drain equally, so don't be surprised if you may have to change one before the others.
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, they will damage the Power Cube beyond repair!
