AGM vs. Flooded — Which Does This Vehicle Need?

Your 2017 Toyota Corolla originally came equipped with a standard flooded lead-acid battery. This type of battery is perfectly adequate for the vehicle's needs and is generally the most economical choice. Flooded batteries require minimal maintenance, mainly ensuring the terminals are clean and corrosion-free.

However, you can upgrade to an Absorbent Glass Mat (AGM) battery. AGM batteries offer several advantages:

• Improved Durability: They are more resistant to vibration and impact.
• Longer Lifespan: Often last longer than traditional flooded batteries.
• Maintenance-Free: No need to check electrolyte levels as they are sealed.
• Better Performance in Extreme Temperatures: Generally perform better in very hot or very cold climates.
• Faster Recharging: They can accept a charge more quickly.

While an AGM battery is typically more expensive upfront, its benefits can justify the cost for many owners, especially if you live in an area with extreme temperatures or frequently make short trips that can be hard on a battery.

2. Power Window Reset: If your automatic up/down windows don
