Is your battery flat? It might be a problem with the alternator rather than the battery itself, especially if the battery is relatively new. An alternator recharges your car battery while the engine is running so that it remains charged. Some cars tell the driver if there is a faulty alternator by having 'ALT' or 'GEN' as warning lights on the dashboard. The good news is that you can easily get a replacement from Parts In Motion. Just enter your registration number to see the correct alternator for your vehicle.
