Are you a proud owner of a Subaru Forester but find yourself constantly replacing the battery? You’re not alone. Many Forester owners have reported issues with their vehicle’s battery dying frequently. In this article, we will explore the reasons behind this issue and provide helpful tips on how to solve it.
- Subaru Forester batteries are known to die frequently due to a variety of issues such as a faulty alternator, corroded terminals, and parasitic drain.
- Regular maintenance such as checking the battery charge and cleaning the terminals can help prevent battery failure.
- Upgrading to a high-quality battery and ensuring proper installation can also improve the longevity of your Forester’s battery.
Why Do Subaru Forester Batteries Die Frequently?
There are several reasons why Subaru Forester batteries tend to die frequently. Let’s take a closer look at each of these issues.
The alternator is responsible for keeping the battery charged while the engine is running. If there is a problem with the alternator, the battery may not be receiving enough charge to stay fully charged, causing it to die frequently.
Over time, the battery terminals can become corroded, hindering their ability to conduct electricity. This can lead to a weak or dead battery.
Parasitic drain occurs when an electrical component in the vehicle continues to draw power even when the car is turned off. This can be caused by a faulty switch or a malfunctioning electrical system, leading to a dead battery.
Extreme temperatures, whether hot or cold, can take a toll on your Forester’s battery. A battery that is exposed to extreme heat or cold for an extended period may become damaged and lose its ability to hold a charge.
Tips to Prevent Battery Failure
Now that we know some of the reasons why Subaru Forester batteries can die frequently, let’s take a look at some tips to prevent battery failure.
Regular maintenance is key to ensuring your Forester’s battery stays in good condition. This includes checking the battery charge and cleaning the terminals regularly to prevent corrosion.
Upgrading Your Battery
Upgrading to a high-quality battery can help prevent battery failure. When replacing your battery, make sure to choose one that is suitable for your Forester’s make and model. Additionally, ensure proper installation to avoid any issues.
Avoid Frequent Short Trips
Frequent short trips can put a strain on your Forester’s battery. Try to limit short trips and allow the battery to charge fully by taking longer trips when possible.
How often should I replace my Forester’s battery?
A typical car battery can last about three to five years, but this can vary depending on usage and maintenance. It is generally recommended to replace your Forester’s battery every four years to prevent unexpected failure.
Can I jump-start my Forester if the battery dies?
Yes, you can jump-start your Forester if the battery dies. However, it is important to follow proper safety procedures when jump-starting a vehicle.
How can I tell if my alternator is failing?
If you notice dimming headlights or a slow crank when starting your Forester, it could be a sign of a failing alternator. A mechanic can perform a diagnostic test to verify if your alternator is the issue.
Subaru Forester batteries can die frequently, but by understanding the causes and following proper maintenance procedures, you can avoid unexpected battery failure. Remember to always choose a high-quality battery and ensure proper installation to improve the longevity of your Forester’s battery.
