When Subaru Uses AGM Batteries

1. Start-Stop Technology:
   • Some newer Subaru models with start-stop systems (which automatically turn off the engine at stops to save fuel) may be equipped with AGM batteries. These systems require a battery that can handle frequent charging and discharging.
2. Vehicles with Higher Electrical Demands:
   • Vehicles that have additional electrical components, such as advanced infotainment systems, heated seats, and multiple sensors, may use AGM batteries for their superior charging capacity and longer lifespan.
3. Premium and Performance Models:
   • Certain premium or high-performance Subaru models may come with an AGM battery for better power management and increased durability.

Benefits of AGM Batteries in Subaru Vehicles

• Durability: AGM batteries are more resistant to vibration and can last longer, making them ideal for vehicles with higher power demands.
• Reliable Power: They offer better deep cycle performance and improved charging efficiency, which is essential for systems like start-stop or for managing extra electrical systems.
• Maintenance-Free: AGM batteries are typically sealed and require less maintenance than traditional flooded lead-acid batteries.

How to Check if Your Subaru Uses an AGM Battery

1. Check the owner’s manual for the type of battery recommended or installed in your vehicle.
2. Look at the battery: AGM batteries are often labeled with the AGM designation on the battery casing.
3. Ask the dealer or mechanic: If you’re unsure, the dealership or a professional technician can confirm the battery type for your specific model.

FAQs About Subaru and AGM Batteries

1. Which Subaru models use AGM batteries?

• Models with start-stop technology or higher electrical demands (like Outback, Legacy, and Forester in newer models) are more likely to use AGM batteries.

2. Can I replace an AGM battery with a regular battery?

• It’s best to use the recommended battery type for your vehicle. Using a regular battery instead of an AGM battery in a start-stop system could cause battery performance issues.

3. Are AGM batteries better than regular batteries?

• AGM batteries are more durable and provide better performance, especially for vehicles with higher electrical needs or start-stop systems. However, they are also more expensive.
