- Touch the multimeter leads to the positive and negative terminals of the 12V battery
- The multimeter will display the battery voltage in volts (V)
- A fully charged 12V battery should read around 12.6V
What to Do if the 12V Battery Level is Low
If the 12V battery level is low, it’s essential to take action to prevent further damage. Here are some steps you can take:
Charge the 12V Battery
If the 12V battery level is low, you can try charging it using a 12V charger or a Tesla-approved accessory. Make sure to follow the manufacturer’s instructions for charging the battery.
Check for Parasitic Drain
Parasitic drain occurs when an electrical component in your Tesla continues to draw power from the 12V battery even when the vehicle is turned off. To check for parasitic drain:
- Disconnect the 12V battery
- Wait for at least 30 minutes to allow any remaining power to drain
- Reconnect the 12V battery and check the voltage using a multimeter
- If the voltage is still low, it may indicate a parasitic drain issue
Replace the 12V Battery
If the 12V battery is old or damaged, it may be necessary to replace it. Tesla recommends replacing the 12V battery every 5-7 years, depending on usage and environmental factors. (See Also: When Should You Replace Tesla Battery? Signs Of Wear)
