Replace the battery charger

The charging circuit on the main board is fried. This is a common issue. You need some good electronic repair skills, and equipment, to replace the problem components

Reset the Roomba: hold down "spot" and "dock/demo" for fifteen seconds, then release and listen for the tune. Then charge the Roomba overnight. The next time you run it, the unit should run longer. If not, call support and let them know you may have a battery problem. 1-877-855-8593 (I strongly encourage you to have the Roomba with you if you call.)
