Can I change my own Lexus battery?

Yes, you can typically change the battery in your Lexus vehicle yourself. However, the process may vary depending on the specific model and year of your Lexus. It's important to follow the proper steps and safety precautions to ensure the job is done correctly.


Steps to Change a Lexus Battery



  • Locate the battery in your Lexus. It is usually found in the engine compartment or under the rear seat.

  • Disconnect the negative (-) battery cable first, then the positive (+) cable.

  • Remove the old battery and clean the battery tray and cable connections.

  • Install the new battery, making sure the positive and negative terminals are properly connected.

  • Reconnect the positive (+) cable first, then the negative (-) cable.

  • Ensure the new battery is securely in place and the connections are tight.

  • Start the engine and let it run for a few minutes to allow the new battery to charge.


It's important to note that some Lexus models may have additional steps or requirements, such as programming the new battery to the vehicle's computer system. Consult your owner's manual or a Lexus service center for specific instructions for your vehicle.


Safety Precautions



  • Wear protective gloves and eye protection when handling the battery.

  • Avoid creating sparks or flames near the battery, as it can produce flammable hydrogen gas.

  • Properly dispose of the old battery according to local regulations.

  • If you're unsure about any part of the process, it's best to have a professional mechanic handle the battery replacement.


By following the proper steps and safety precautions, you can successfully change the battery in your Lexus vehicle yourself. However, if you're not comfortable with the process or have any concerns, it's always best to consult a Lexus service center for assistance.

Can you change a Lexus battery yourself?


Thankfully, it is possible to replace a Lexus car battery by yourself if you are feeling up to it, or you can always engage professional battery replacement services to get the job done quickly and efficiently.



How much does Lexus charge to replace a battery?


The cost to replace a Lexus battery varies significantly: a standard 12V battery replacement costs around $100-$250, while a hybrid battery replacement can range from $2,000 to $8,000. For a standard battery, a dealership may charge between $310-$362, while independent shops and auto parts stores will have lower prices for the parts themselves, though labor costs will also vary. 
Standard 12V battery replacement

  • Cost: Typically between $100 and $250 for the battery alone. 
  • Total with labor: Can range from approximately $250 to $400 or more, depending on the service location. 
  • Where to get it: Dealerships, auto parts stores, or independent service centers. 

Hybrid battery replacement
  • Cost: A wide range from $2,000 to $8,000, depending on the vehicle model and other factors. 
  • Factors: The size and technology of the hybrid battery make it much more expensive than a standard car battery. 
  • Where to get it: Typically requires a specialized service center, such as a dealership or a hybrid specialist. 
  • Note: Some issues that appear to be hybrid battery problems can be due to other components, so it's important to get a full inspection first. 



How do I reset my Lexus after changing the battery?


To reset your Lexus after a battery change, start by performing a hard reset by disconnecting both terminals, touching them together for at least 30 minutes, and then reconnecting the positive cable first. Next, reset specific systems by turning the ignition to the "ON" position, letting the engine idle for a few minutes, and performing individual component resets like those for the power windows, steering angle sensor, and power hatch. Finally, drive the vehicle for about 10 miles to allow the computer to relearn and adjust to the new battery. 
Hard reset (Recommended first step)

  • Disconnect the negative terminal, followed by the positive terminal. 
  • Touch the disconnected positive and negative cables together for at least 30 minutes to drain residual power and reset all vehicle modules. 
  • Reconnect the positive battery cable, followed by the negative cable.

System and component resets
  • Idle relearn: Turn the ignition to "ON" (do not start) for 30 seconds. Then, start the engine and let it idle for 2-3 minutes without touching the gas pedal. Turn off the car and repeat this process. 
  • Window reset: For each window, roll it all the way down, wait a few seconds, then roll it all the way up and hold the switch for a couple of seconds. Repeat for each window. 
  • Steering angle sensor: If the steering wheel light stays on, turn the steering wheel slowly all the way to the left and then all the way to the right until the light goes off. 
  • Rear hatch: If your vehicle has an automatic rear hatch, you may need to manually open and close it a few times.

Drive the vehicle 
  • After performing the resets, drive the vehicle for about 10 miles to allow the computer to recalibrate and learn the new battery's performance. 
  • Be aware that the engine may run roughly for a few minutes as the idle learning system adjusts.
