As a Subaru owner, you rely on your key fob daily for seamless access and security features. But have you ever considered what powers this essential device and how to ensure its longevity? At keyfobx.com, we specialize in automotive solutions, and understanding the right battery for your key fob Subaru is crucial for uninterrupted vehicle operation. Let’s delve into the specifics of key fob batteries, debunk some common myths, and guide you in making the best choices to keep your Subaru key fob functioning perfectly.
Debunking the Myth: Air Exposure and Your Key Fob Battery
You might have heard that air exposure is the primary culprit behind the depletion of your key fob battery. While it’s true for certain types of air-activated batteries used in hearing aids or some specialized devices, this isn’t the main issue for the lithium coin cell batteries that power most Subaru key fobs. The reality is a bit more nuanced.
The common CR2032 batteries found in Subaru key fobs and many other devices are not hermetically sealed, yet they are designed to last for years. If air alone were the enemy, these batteries would have extremely short shelf lives, which is not the case. Instead, factors like humidity and temperature fluctuations play a more significant role in battery degradation.
The Real Drain: Humidity and Temperature Changes
The real challenge for your Battery For Key Fob Subaru lies in environmental factors, primarily humidity and temperature variations. Lithium coin cell batteries, like the CR2032, are susceptible to self-discharge over time, and this process is accelerated in environments with high humidity, especially above 75%, a common condition in many regions, particularly during summer months without air conditioning.
These batteries can also be affected by transient shorts or corrosion, which are more likely to occur in humid conditions, leading to quicker discharge. Think about the conditions your key fob endures daily – from the cold of winter mornings to the heat of summer afternoons inside a parked car. These drastic changes in temperature and humidity put stress on the battery, impacting its lifespan.
Choosing the Right Battery and Understanding Packaging
When selecting a battery for key fob Subaru, opting for reputable brands like Duracell or Energizer is generally a wise choice. These brands often guarantee a 10-year shelf life, and you might notice that batteries with such guarantees sometimes come in double-sealed packaging for extra protection until use.
It’s important to understand that the primary purpose of modern battery packaging, especially for button cell batteries, is child safety. Driven by safety standards and competitive market pressures, manufacturers have adopted child-resistant packaging. While this packaging is beneficial for safety, it’s not necessarily designed to be completely airtight for maximizing battery longevity. Many common blister packs, while making it difficult to access batteries for children, are not hermetically sealed.
Extending the Life of Your Subaru Key Fob Battery
To maximize the lifespan of your battery for key fob Subaru, consider these tips:
- Avoid Extreme Temperatures: Try to keep your key fob away from direct sunlight and extreme temperatures, both hot and cold. Avoid leaving it in your car for extended periods, especially during hot summer days or freezing winter nights.
- Control Humidity: While you can’t control the ambient humidity, try to store spare batteries and your key fob in relatively dry places.
- Quality Matters: Invest in quality batteries from reputable brands. While cheaper options might be tempting, they may not offer the same longevity or reliability.
- Check Expiry Dates: Always check the use-by date on the battery packaging to ensure you are using a fresh battery.
Conclusion: Battery for Key Fob Subaru – Longevity and Care
In conclusion, while air exposure isn’t the main enemy of your battery for key fob Subaru, humidity and temperature changes are significant factors that contribute to battery drain. Choosing a quality CR2032 battery, understanding the purpose of battery packaging, and taking simple steps to mitigate environmental stresses can significantly extend the life of your key fob battery. By being informed and proactive, you can ensure that your Subaru key fob remains reliable and ready whenever you need it.
