A car battery is what gets your car to actually start when you turn it on. The battery powers the alternator (a little motor) to turn over the engine until it starts up into idle. Batteries are specific to your car and taking care of it will ensure that it lasts as long as it should. If your car is taking a bit longer to turn over or start then your battery might need replacing. JAX offers full battery inspection and replacement as well as vehicle safety inspections.
