Battery Service in Ann Arbor, MI

Your vehicle’s battery provides the necessary electrical energy to start the engine and power various systems. However, like all mechanical components, batteries deteriorate over time and need to be replaced. That’s why it’s important to know when and why a person may need to have their car, truck, or SUV battery replaced. When your vehicle needs its battery serviced or replaced in Ann Arbor, Michigan, you can trust the certified technicians at Subaru of Ann Arbor’s service department.

Before delving into when a replacement may be necessary, it’s important to first understand the primary functions of a vehicle battery. The battery has two main roles: initial starting power and electrical energy storage. When you turn the key in your ignition, the battery supplies a high burst of electrical energy to the starter motor, initiating the engine's combustion process. Additionally, while the engine is running, the battery power is used to run the electrical systems, such as lights, radio, air conditioning, and other accessories.

Signs Your Vehicle’s Battery Needs to Be Replaced

Here are some of the various factors that can determine when a battery replacement is needed:

Age and Usage:

The lifespan of a battery can vary depending on its quality and usage patterns. Typically, a standard car battery lasts between three to five years. However, harsh weather conditions, frequent short trips, and constantly running high-powered accessories can reduce its lifespan. If a battery is nearing or has exceeded its expected lifespan, it is advisable to have it replaced proactively to avoid unexpected breakdowns.

Slow Engine Crank:

One of the most common signs that a battery is losing its capacity is a slow or weak engine crank when starting the vehicle. As the battery deteriorates, it may struggle to deliver the required electrical power to turn over the engine effectively. If you notice that the engine is slow to start, especially on cold mornings or after the vehicle has been sitting for an extended period, it could be an indication that the battery is on its way out.

Dimming Lights and Electrical Issues:

The battery in your car not only starts the engine but also ensures power for the electrical components. If you notice that your headlights, interior lights, or other electrical systems are dimming or flickering, it could be a sign of a dying battery. Additionally, if you experience frequent issues with power windows rolling up or down slowly, or the radio resetting itself regularly, it may imply an insufficient power supply from the battery.

Corrosion and Physical Damage:

Over time, the battery terminals can accumulate corrosion, which restricts the proper flow of electricity from the battery to the vehicle's electrical system. When inspecting the battery, check for any signs of rust or white, ashy substances around the terminals. Furthermore, physical damage to the battery, such as cracks or leaks, can also lead to a loss of its ability to hold a charge and require immediate replacement.

Extreme Weather Conditions:

Batteries are heavily affected by weather extremes - both hot and cold. In colder climates, the chemical reactions that generate electricity slow down, causing a reduction in the battery's overall power output. Similarly, high heat can accelerate the chemical reactions, causing the battery to overheat and degrade faster. If you live in an area with extremely hot or cold weather, you may need to replace your battery more frequently compared to milder climates.

Extended Periods of Inactivity:

If a vehicle sits idle for an extended period, such as during a long vacation or due to not being regularly used, it can result in a discharged or weakened battery. When a vehicle is not running, various electrical systems continue to draw power, slowly draining the battery. If you plan on leaving your car unused for an extended period, it is advisable to connect it to a battery maintainer or consider disconnecting the battery to prevent unnecessary discharge.

Jump-Start Dependence:

If you find yourself frequently needing to jump-start your car with the help of another vehicle or a jump-starting device, it is a clear sign that your battery is no longer holding a sufficient charge. While jump-starting may temporarily solve the problem, it is not a long-term solution. Depending on external power every time you start your vehicle indicates that the battery needs to be replaced.
