The battery’s job is to start the vehicle. Once running, the alternator powers all the electronics and recharges the battery. If the alternator is not working properly, the battery will not charge and the vehicle will not start. Over time, batteries lose their charge. If your vehicle sits, the battery will die. A car battery typically only lasts 5 years. After this, there is not enough reserve capacity to keep the battery charged. If the battery light comes on while driving, the alternator may be to blame.
