Solution
1. Preparation
  • Tools Required: Multimeter, OBD-II scanner, Tesla app, safety gloves.
  • Ensure the vehicle is parked on a flat surface and turned off.
  • Wear safety gloves to protect from any electrical hazards.
2. Check Battery Health via Tesla App
  • Open the Tesla app on your smartphone.
  • Navigate to the "Battery" section.
  • Review the "Battery Health" indicator and note the percentage of health remaining.
  • Check for any alerts or notifications regarding battery issues.
3. Retrieve Diagnostic Codes
  • Connect the OBD-II scanner to the vehicle’s OBD-II port.
  • Turn on the ignition to the accessory position without starting the engine.
  • Use the scanner to read any diagnostic trouble codes (DTCs) related to the battery.
  • Document any codes for further investigation.
4. Measure Battery Voltage
  • Set the multimeter to the DC voltage setting.
  • Disconnect the negative terminal of the battery to ensure safety.
  • Connect the positive probe of the multimeter to the positive terminal and the negative probe to the negative terminal.
  • Record the voltage reading. A healthy 12V battery should read between 12.4V to 12.7V when fully charged.
  • Reconnect the negative terminal.
5. Inspect Battery Condition
  • Visually inspect the battery for any signs of physical damage, such as swelling or leaks.
  • Check battery terminals for corrosion and clean if necessary using a mixture of baking soda and water.
  • Ensure all connections are secure and tight.
