Tesla Maximum Battery Charge Level Reduced

The error message “Maximum battery charge level reduced” on a Tesla indicates that the battery management system (BMS) has detected an imbalance within the battery pack. This can happen for a number of reasons, including:

  • The battery has aged and degraded over time.
  • The battery has been exposed to extreme temperatures.
  • The battery has been damaged in a collision.
  • There is a manufacturing defect in the battery pack.

When the BMS detects an imbalance, it will reduce the maximum charge level of the battery to prevent further damage. This can also affect the car’s range.

If you see the error message “Maximum battery charge level reduced“, you should contact a Tesla service center to have the battery inspected. The service center will be able to diagnose the problem and recommend the best course of action.

In some cases, the imbalance in the battery pack can be corrected by recalibrating the BMS. However, if the battery is severely damaged, it may need to be replaced.

The Tesla battery warranty covers 70% of the original battery capacity for 8 years or 100,000 miles (whichever comes first). If your Tesla is still under warranty, the battery replacement will be covered at no cost to you.
