Subaru owners have been experiencing battery drain issues for years. Your Subaru battery may be draining faster than it should, leaving you stranded in the middle of nowhere. In this article, we’ll discuss the common causes of battery drain in Subaru vehicles and provide you with some tips and tricks to prevent it from happening. So, if you’re tired of your battery dying every few months, read on!
What Causes Battery Drain in Subaru Vehicles?
There are several reasons why your Subaru’s battery may be draining faster than it should. Here are some of the most common causes:
1. Parasitic Drain
Parasitic drain occurs when there is a continuous electrical load on the battery even when the car is turned off. This can happen when there is a faulty component in the car’s electrical system, such as a malfunctioning alternator or a short circuit in the wiring. Parasitic drain can also occur when you leave an accessory plugged in, such as a phone charger, for an extended period.
2. Battery Age
Batteries have a limited lifespan, and they will eventually wear out over time. If your battery is several years old, it may not be holding a charge as well as it used to, leading to faster drain.
3. Extreme Temperatures
Extreme temperatures, whether hot or cold, can put a strain on your car’s battery. In cold weather, the battery’s chemical reaction slows down, making it harder to start the car. In hot weather, the battery can overheat, causing damage to the internal components.
Tips and Tricks to Fix Battery Drain in Subaru Vehicles
Now that we know what causes battery drain in Subaru vehicles let’s discuss some tips and tricks to prevent it from happening.
1. Check for Parasitic Drain
If you suspect that parasitic drain is causing your battery to drain faster than it should, you can perform a simple test to check. Disconnect the negative battery cable, and then use a multimeter to measure the electrical current running through the cable. If the reading is higher than 50 milliamps, there is a parasitic drain in the system that needs to be fixed.
2. Keep Your Battery Charged
Keeping your battery charged is essential to extend its lifespan. If you don’t drive your car frequently, consider investing in a trickle charger to keep the battery topped up. You can also take your car for a drive once a week to keep the battery charged.
3. Replace Your Battery
If your battery is several years old and not holding a charge as well as it used to, it may be time to replace it. A new battery will provide better performance and prevent future battery drain issues.
Conclusion
Battery drain issues in Subaru vehicles can be frustrating, but they are fixable. By following the tips and tricks in this article, you can prevent battery drain and extend the lifespan of your battery. Remember to check for parasitic drain, keep your battery charged, and replace your battery if necessary. With these simple steps, you can avoid getting stranded with a dead battery.
