How To Replace 12v Lead Acid Battery With 12v Lithium In Your Tesla

By Andrew Stephens

A common upgrade for Tesla owners looking to extend the lifespan and improve the performance of their cars is switching from a 12V lead-acid to a 12V lithium battery. Compared to their lead-acid cousins, lithium batteries have many benefits, such as a longer lifespan, reduced weight, and increased efficiency.

A common upgrade for Tesla owners

Switching from a traditional lead-acid battery to a 12V lithium battery in your Tesla offers numerous benefits, including improved longevity and efficiency. Lithium a low-voltage battery, known for its low voltage consumption and minimal power draw in low power consumption mode, can significantly enhance your vehicle's performance. This upgrade not only reduces the strain on the main battery pack but also optimizes remote access features and onboard computer operations. Unlike lead-acid batteries, lithium batteries perform better in cold weather and can help maintain efficient battery service mode.

As a result, your Tesla's new battery, such as the Ohmmu battery, ensures seamless operation and better management of power across all components, including the rear seat and other systems This tutorial will show you how to swap out your Tesla's 12V lead-acid battery for a 12V lithium battery. It covers all Tesla models, including the Model S, Model 3, Model X, Model Y, and the recently released Cybertruck.

Why Make the Switch to Lithium Batteries?

Why Make the Switch to Lithium Batteries?
  1. Longevity: Usually lasting five to ten years, lithium batteries are far more durable than lead-acid batteries.
  2. Weight: Since lithium batteries are far lighter than other battery types, they can help vehicles be lighter overall and run more efficiently.
  3. Performance: The systems in your car will always have a steady source of power thanks to lithium batteries, which offer more stable voltage and improved performance at high temperatures.
  4. Maintenance: Lithium batteries are less prone to problems like sulfation and require less maintenance than lead-acid batteries.

Items You'll Require Lithium Battery, 12V:

Make sure it fits your Tesla model and is either the same capacity as the stock battery or greater.

  • Wrenches and a socket set: These are needed to take out and replace the battery.
  • Battery Hold-Down Bracket: To hold the replacement battery firmly in position if necessary.
  • Insulating Materials: To guarantee that the battery is properly insulated and protected.
  • Multimeter: To ensure correct installation and to check the voltage.
  • Tesla Battery Tray Adapter: If needed, specific to some models.

Safety First Preparation:

Before starting the replacement procedure, make sure the car is turned off and disconnected from any power sources. Assemble Tools and Equipment: Assemble the tools and equipment that are required. Make that your Tesla is compatible with the new 12V li-ion battery and that it is completely charged.

Model S Replacement Procedure Find the Battery:

The front trunk (frunk) contains the 12V lead-acid battery. To reach the battery, pry open the frunk and take off the plastic cover. Disconnect the battery by unscrewing the positive and negative terminals sequentially with a wrench. To remove the battery, unscrew and take off any mounting or hold-down brackets. Gently raise the old battery.

Insert the new 12V li-ion battery into the tray to install it. Reconnect the connections, beginning with the positive terminal, and secure it with any brackets that may be required.

Check the Installation: Make sure the connections are tight and the voltage is accurate by using a multimeter.

Model 3 Find the Battery:

The front trunk of the Model 3 contains a 12V battery. To reach the battery, pry open the frunk and take off the lid. Disconnect the battery by disconnecting the positive and negative terminals in turn. Take out the battery by unscrewing and removing any mounting parts or brackets. Remove the old battery by lifting it out.

Li-ion battery installation: Insert the brand-new 12V lithium battery into the tray, fasten it with any required brackets, and reconnect the terminal, starting with a positive terminal.

Check the Installation: Verify the connections and voltage to make sure everything is installed correctly.

The Model X Find the Battery:

The Model X's 12V battery can be found in the front trunk. Take the lid off, open the frunk, and find the battery. Disconnect the battery by disconnecting the positive and negative terminals in turn. Take off any hold-down brackets or mounts, then carefully lift out the old battery to remove it.

Installing the Lithium Battery: Reconnect the terminals, beginning with the positive terminal, after placing the new 12V li-ion battery in the tray and tightening it. Verify Connections: Ascertain that the battery is firmly inserted and that the connections are made correctly.

  • Detach the Battery: Just like with other models, detach the positive and negative terminals in turn. Take off any hold-down brackets or mounts, then carefully lift out the old battery to remove it.
  • Install the Lithium Battery: Make sure the new lithium-ion battery has the necessary voltage since the Cybertruck runs on a 16V battery. Install it in a similar manner, reattaching the terminals, and fastening it with any required brackets.
  • Check the Installation: Check the voltage and make sure the installation is accurate with a multimeter. Final Inspections and Security Verify connections twice to make sure there are no loose wires and that all terminals are firmly attached.
  • Test Vehicle Systems: Turn on your Tesla and check that all of the systems are operating as they should.
  • Get Rid of Old Battery: Take the old lead-acid battery to a recycling center or an auto parts store that takes back batteries for proper disposal.

Conclusion

In summary, Your Tesla's electrical systems will operate better and last longer if the 12V lead-acid battery is swapped out for a 12V lithium battery. This is an upgrade that is well worth the money, regardless of whether you possess a Model S, Model 3, Model X, Model Y, or the new Cybertruck. To prevent any problems, make sure the replacement battery is compatible with your particular model and follow the installation instructions exactly.
