Locate and access the battery

When changing the battery in your 2020 Toyota Corolla, the first step is finding the location of the old battery. In most cases, the battery is located under the hood of your car. To access it:

  • Pop the hood of your car by pulling the hood release lever usually found below the steering wheel.
  • Once the hood is open, secure it with the prop rod to ensure it stays up while you work.
  • Locate the battery. It is usually a rectangular box with two cables attached to it, often concealed under a plastic covering.

Before you start removing the old battery, it’s essential to identify the positive and negative terminals. The positive terminal is typically marked with a “+” sign, while the negative terminal has a “-” sign. Familiarize yourself with these to ensure you disconnect and reconnect the cables correctly during the battery replacement process.

Disconnect the old battery

  • Start by disconnecting the negative cable first to prevent any electrical mishaps.
  • Use a wrench or socket to loosen the nut on the negative terminal.
  • Once the negative cable is removed, proceed to disconnect the positive cable using the same method.
  • After removing both cables, carefully lift out the old battery from its housing.
  • Be mindful of any clips or straps holding the battery in place.
