Lecture Notes: Toyota RAV4 Battery Replacement

Tools Needed

• Socket Wrench Tools
  • 3/8 Socket
  • 3-inch Extension
  • 10 mm socket (used for all battery-related components)
• Other Tools
  • Open wrench

Battery Removal Process

1. Safety First:
   • Always start by removing the negative terminal first to prevent electrical issues (similar to cutting power at a house).
   • Ensure terminals do not touch any metal parts.
2. Remove Battery Holder:
   • Use a 10 mm socket to loosen the holder.
   • Backside does not need to be completely removed, just loosen sufficiently.
3. Take Out Battery:
   • Lift and remove after loosening.
   • Be cautious of the metal bracket that holds the battery in place.

Installing the New Battery

1. Place New Battery:
   • Align in the plastic holes to ensure stability.
   • Remove protective caps from the battery terminals.
2. Preventative Measures:
   • Apply dielectric grease or terminal grease to prevent corrosion.
   • Note: Corrosion often occurs after 3+ years or in certain weather conditions.
3. Mount Battery:
   • Reconnect to the metal side bracket.
   • Use original bolt to secure, tighten with 10 mm socket.
   • Ensure battery is sturdy and does not move.

Reconnecting the Terminals

1. Positive Terminal First:
   • Attach and secure loosely, avoid over-tightening.
   • Ensure it is stable with a small wiggle.
2. Negative Terminal Last:
   • Connect last to prevent sparks and ensure safety.
   • A small spark may occur; it's normal, especially if the car is on.
   • Tighten adequately without over-tightening.

Final Steps

• Once both terminals are connected and secured, start the car to ensure the battery is functioning correctly.
• Confirm all connections are stable and secured before completing the process.
