Car Battery Service in Fairlington, VA

A dead battery is the number-one cause of roadside breakdowns, and Northern Virginia's temperature extremes — scorching summers and freezing winters — are especially hard on batteries. At Fairlington Sunoco Service Center in Fairlington, VA, we test your battery and charging system to catch problems before they leave you stranded in a parking lot or on the side of I-395. If you need a replacement, we carry quality batteries for all makes and models, installed while you wait.

How Your Battery and Charging System Work

Your battery provides the initial surge of power to start your engine and runs electrical accessories when the engine is off. Once running, the alternator takes over, recharging the battery and powering your vehicle's electrical systems. A failing battery, worn alternator, or corroded connections can cause slow cranking, dim lights, or complete no-start situations. Our technicians test the entire charging circuit — battery, alternator, and starter — to identify the exact source of the problem.
