Locate the car battery in your Honda Odyssey

When changing the battery in your Honda Odyssey, the first step is locating the battery. In most Honda Odyssey models, the battery can be found under the hood, typically on the driver’s side.

To find the battery, open the hood of your Odyssey. Once the hood is open, look for a rectangular box with cables connected to it. That box is your car battery.

In some Honda Odyssey models, the battery may be under a cover or air intake duct. If you can’t find the battery immediately, refer to your owner’s manual for specific instructions on locating the battery in your Odyssey model.

When it’s time to replace your Honda Odyssey’s battery, the first step is removing the old one. Follow these simple steps to safely take out the old car battery:

  • Gather your tools: You’ll need safety gloves and protective eyewear to prevent any accidents.
  • Locate the battery: As mentioned earlier, the battery is typically found under the hood on the driver’s side.
  • Identify the terminals: The battery has two terminals: the positive (+) and negative (-). Take note of their positions.

  • Remove the battery tie-down: Depending on your model, there may be a tie-down securing the battery in place. Unscrew it before lifting the battery out.
  • Lift out the old battery: With the cables disconnected and tie-down removed, carefully lift out the old battery from its compartment.
