Your battery is the 12V battery under the hood, and replacing it means disconnecting the old unit, removing the hold-down, and installing the new one with the correct clamp and terminal order. On your RAV4, the job is straightforward, but you must keep the key away from the vehicle and handle the terminals carefully to avoid short circuits.

Difficulty Level: Beginner | Estimated Time: 0.5-1 hour

⚠️ Safety & Precautions

• Wear safety glasses and gloves. Battery acid and corrosion can burn skin and eyes.
• Turn the ignition off, remove the key/fob from the vehicle, and keep it away from the car.
• Do not let a wrench touch both battery terminals or the body at the same time.
• Disconnect the negative terminal first and reconnect it last.
• If the battery has a vent tube, transfer it to the new battery. A vent tube lets battery gases exit safely.
• No battery disconnect programming is required for this repair on your RAV4.
