Battery and Alternator: The Heart and Soul of Your Vehicle’s Electronic System

Your vehicle’s battery is the source of the electrical current necessary to start the engine. A healthy battery will always have a voltage reading around 12.6V. While running, the alternator will slightly overcharge the battery to around 13.6V – 14.6V. The battery provides power to your vehicle’s accessories and electrical parts; it allows them to operate even when your vehicle’s engine is not running. Additionally, components such as your engine and starter rely on the battery for power; they cannot run without a properly functioning battery. Your battery is your vehicle’s voltage stabilizer for the entire electrical system. Most vehicle batteries need to be replaced every few years, depending on the conditions in which you drive. Extreme weather, continued use of vehicle accessories and other conditions can lead to shorter battery life. Over time, your battery loses juice, and you may need to occasionally jump-start your vehicle in order to get it running. If your vehicle is showing signs of lessened battery life, such as delayed start time, you may need to get your battery replaced. A failing battery will display signs such as flickering headlights, dim interior lights, or the famous “click but no start” condition. When any of these signs manifest themselves, bring your vehicle into A-Len Automotive Service for a charging system check. This check will test the output of the alternator, as well as the health of the battery.

The alternator is the electronic current generator of the charging system. This components keeps the battery at full charge while the vehicle is running, regardless of how many accessories you have on at the time. Symptoms of a failing alternator are similar to those of a failing battery, so it is best to get a trusted shop to test the health of both components to ensure proper parts replacement for you.
