Sphero comes with his very own induction charger. When his battery runs low, you can revive him heavy side down in the charger. To find his heavy side, place him on a hard surface like a table. Sphero will naturally settle with this sweet spot at the bottom. Remove any covers from Sphero and pop him in the charger in this position. The charger will blink blue when charging begins. After about 3 hours, the blue light becomes solid and Sphero is ready to roll. He will play at top speed for up to 60 minutes before he needs another rest.
Feel free to leave Sphero plugged in and on his charging base for extended periods of time.
IMPORTANT SAFETY TIP: DO NOT PLACE ANY OBJECTS IN THE SPHERO CHARGER OTHER THAN SPHERO. PLACING COINS OR METAL OBJECTS INTO THE CHARGER COULD CAUSE THE METAL OBJECTS TO HEAT AND BURN ON CONTACT.
EXAMINE SPHERO AND THE CHARGER FOR SIGNS OF DEFORMATION OR MELTING. IF ANY SIGNS ARE DETECTED - CEASE USE AND RETURN TO SPHERO FOR REPAIR OR REPLACEMENT.
