How to Replace the 12V Battery | 2021+ Toyota Sienna (4th Gen)

Need to replace the 12V battery on your Toyota Sienna? In this step-by-step guide, I show you how to swap out the factory OEM battery on my 2021 Toyota Sienna XLE AWD with a Duralast AGM H5-AGMEL battery from AutoZone. This battery comes with a 5-year warranty and is a great upgrade for 4th-generation Siennas (2021 and newer).

I’ll walk you through the tools needed and the installation process. At the end, I also recommend the jump starter I keep stored in my van for emergencies.

🔧 Tools Needed:
• 10mm socket wrench or wrench
