Later, in the article, we’ll be discussing more about Tesla Model Y jump starting. So, if you are following any issue related to jumpstarting a Tesla Model Y, then make sure to go through the whole article.

How does A Tesla Battery Work?

Tesla is one of the leading innovators of the electric vehicle and it has brought some sudden changes in the battery technology. Tesla implemented lots of technology in their battery as well as EV to increase the power and performance of the car. Now, Tesla Model 3 and Tesla Model Y are of selling cars which are offering the longest range with good battery performance.

Now, Tesla is fully shifting to lithium-ion batteries to improve the performance and ability of EVs. The lithium-ion battery is just the same as you have in your smartphone, laptop, and other high-powered device. The good thing about the lithium-ion battery is, it offers longevity and power like a smartphone. But smartphones use very few lithium-ion cells in their battery.

Tesla uses a huge number of lithium-ion cells in their battery to power up the engine because you all know batteries are the only source of power in electric vehicles. A good power supply is needed to replace an internal combustion engine. The main battery of the Tesla can’t be charged while driving like the hybrid battery. To power up the main battery, it must be charged from the external output.

The Tesla lithium-ion battery sends a constant supply of power to the engine and makes the vehicle move. Tesla lithium-ion batteries are very optimistic in delivering power. It has the ability to hold power for a long time as well as charge quickly.

Jump Starting Tesla Lead-Acid and Lithium-Ion battery

Tesla EVs are among the best sellers in the world. It offers a good range and longevity in the vehicles. Talking about the Tesla Model Y is the one and only vehicle that comes under the list of top-selling cars in the U.S. The Tesla Model 3 and Tesla Model Y gain the majority of sales worldwide. But do you know whether it is recommended to jump-start a Tesla Model Y or not?


Tesla never recommends using Tesla Model Y and Tesla Model 3 to jump-start the battery of another car. It can have a significant impact on the Tesla batteries. The process of jump-starting can deplete the battery potential and result in damage to the battery.

AspectJump Starting with Lead-Acid BatteryJump Starting with Lithium-Ion Battery
Voltage Level12 voltsAround 400 volts
Safety PrecautionsPolarity, sparks, and hydrogen gas buildup considerationsNot recommended or supported
Power RequirementsSurge of power required to start the vehicleLithium-ion battery management system requires specific charging protocols
Assistance OptionsAnother vehicle or portable jump starter deviceTesla’s roadside assistance or certified service center
Manufacturer’s GuidanceFollow the vehicle’s manual or manufacturer’s recommendationsContact Tesla for specific procedures and recommendations

Jump start a car with the Tesla Model Y can have a lot of impact on the battery health and it has a high possibility of being unsafe. If the plug cables are inserted into the incorrect points, it may lead to dangerous accidents. So, in the case of an emergency, it is always recommended to visit the battery professional while jump-starting your car.

Jump-starting a lithium-ion battery is pretty much easier and everyone can easily perform it with the help of a proper guide. So, to make your work easier we’ve prepared a detailed guide to jump-starting your Tesla.

Steps to Jumpstart your 12V Battery In Tesla

What will happen if your Tesla Model Y is completely out of a power source and all the features of the car are locked? You must be thinking what is the work of a 12V Tesla battery. To resume the power again in your Tesla requires a 12V battery to jump-start your car again.

But before doing this make sure to keep your door and windows open to keep locking yourself out. Below are the steps highlighted to jump-start your Tesla 12V battery.

  1. At first, you have to take an external 12V jump starter in order to perform jump-starting your Tesla Model Y.
  2. Tear out the eye cover placed in the front bumper by the driver’s side. You can do it by pressing the top cover inward. You have to pull the cover towards you. To make your work easier let me tell you this is the place where the tow hook is present.
  3. Now, the wire attached to the cover will depend upon the type of model you have. The wire will be attached just in the hole or you have to pull them out gently.
  4. You have to connect the 12V jump starter with the red positive cable to the car’s red positive cable. The same will be followed in the negative terminal. The black negative terminal of the 12V starter will be connected to the car’s black negative terminal.
  5. Apply maximum power with the external jump starter to pop up the frunk.
  6. Once the frunk opens, disconnect the connected cables, but always remember, the black negative terminal should be removed first then the red positive terminal.
  7. Now, connect both the wires back to the tow cover and insert wires into the opening. You should align the cover into the position first and then push it into the desired place.
  8. Tear off the black and large plastic panel of the 12V battery. You must be wondering where it is located, the 12V battery is located above the frunk compartment of the vehicles but there may be differences in the battery location in the different Tesla Models. To take off the panel you only have to pull approximately 12 clips rather than using any specific tools.
  9. Uncovering the large plastic 12V battery panel, you wil see a black cabin intake panel on the passenger side of the car. You can easily remove it by pulling it towards yourself or above the clips.
  10. Now, you have to stay very careful while connecting the red positive cable of the car with the red positive cable of the 12V battery. A small mistake while connecting wires may lead to a short circuit in the battery components.
  11. Connect the black negative terminal of the 12V battery with the black negative terminal of the car and deliver an external power supply to the battery.
  12. You should wait about 10 to 20 minutes, and let the car process some power to the electrical components. After the interval of 20 minutes, your car will be able to power up the whole computer components. Give some time to acquire charge to the battery.
  13. After charging disconnect the joined cables, always remember to disconnect the black first then the red cable.
  14. Replace the panel back into place and make sure it is properly aligned before pushing it to the center. If it is not properly aligned the components may break easily.
  15. Now, you are ready to take your vehicles to the nearest charging station and charge up. Once the main battery of the Tesla Model Y is completely charged it will automatically start charging the 12V secondary battery.
