I've had my TCH for just over one week. Drove it to Florida and back to Georgia last week, and have been driving local roads this week. I've noticed that the battery on the screen that shows the engine and battery usage never shows a fully charged state. Is that normal? It stays around the Level 2 status (comparing it to the pictures in the owners manual). Should I be concerned that something isn't right? Or should I just keep driving and not worry so much?
