Common Causes of a Dead Tesla Battery
When your Tesla won’t turn on, the most likely culprit is a dead battery. But what exactly causes a Tesla battery to drain to the point of not being able to start the car? In this section, we’ll explore the common causes of a dead Tesla battery and what you can do to prevent them.
1. Low Battery Charge
One of the most obvious reasons for a dead Tesla battery is a low charge. If you’ve been driving your Tesla regularly and haven’t had a chance to charge it, the battery may have drained to the point where it can’t start the car. This is especially true if you’ve been driving in cold weather, as cold temperatures can reduce the battery’s range and increase its drain.
To avoid this, make sure to charge your Tesla regularly, especially during the winter months. You can set up a charging schedule on your Tesla app to remind you when it’s time to charge your car.
2. Parasitic Drain
Parasitic drain refers to the slow discharge of a battery when the car is turned off. This can happen when there’s an electrical component in the car that’s still drawing power, even when the car is turned off. Examples include phone chargers, GPS devices, and alarm systems.

To prevent parasitic drain, make sure to turn off all electrical components when you turn off the car. You can also consider installing a battery saver, which can detect when the car is turned off and cut power to the electrical components.
3. Faulty 12V Battery
Teslas have two batteries: the high-voltage battery that powers the electric motor and the 12V battery that powers the car’s accessories. If the 12V battery is dead or faulty, it can prevent the car from starting.
To prevent this, make sure to maintain your 12V battery regularly. Check the battery terminals for corrosion and clean them if necessary. You can also consider replacing the 12V battery every 5-7 years or as recommended by Tesla.
4. Software Issues
In some cases, software issues can prevent your Tesla from starting. This can happen if there’s a bug in the car’s software or if the software is out of date.
To prevent this, make sure to keep your Tesla’s software up to date. You can check for software updates on your Tesla app and install them as needed. You can also contact Tesla’s customer support if you suspect a software issue is preventing your car from starting.
5. Faulty Charging Port
A faulty charging port can prevent your Tesla from charging, which can lead to a dead battery. If the charging port is damaged or corroded, it may not be able to connect properly to the charging cable.
To prevent this, make sure to clean the charging port regularly and inspect it for damage. You can also consider having the charging port replaced if it’s damaged beyond repair.
Troubleshooting a Dead Tesla Battery
If your Tesla won’t turn on, there are several steps you can take to troubleshoot the issue. Here are some steps to follow:
Step 1: Check the 12V Battery
The first step is to check the 12V battery. Make sure it’s fully charged and that the terminals are clean and free of corrosion. If the 12V battery is dead, you can try jump-starting it or replacing it if necessary.
Step 2: Check the High-Voltage Battery
If the 12V battery is okay, the next step is to check the high-voltage battery. Make sure it’s fully charged and that there are no error messages on the dashboard. If the high-voltage battery is dead, you may need to have it replaced or repaired by a Tesla technician.
Step 3: Check the Charging Port
If the batteries are okay, the next step is to check the charging port. Make sure it’s clean and free of corrosion, and that the charging cable is securely connected.
Step 4: Check for Software Issues
