Cell Defect Detected

What does 26 mean?

The battery management system (BMS) or charger has identified a defect within one or more cells of the connected battery. This could indicate a severe internal issue such as a shorted cell, an open circuit cell, or significantly degraded capacity in a specific cell.

• An internal short circuit within a battery cell, leading to rapid self-discharge or localized heating.
• An open circuit within a cell or a faulty connection between cells.
• Significant imbalance in voltage or capacity degradation of a specific cell or cell group within the battery pack.

Click steps to track your progress.

1. 1

   Immediately isolate the battery from the charger and any loads.

2. 2

   Use a battery diagnostic tool, if available, to identify the specific defective cell or cell group within the battery pack.

3. 3

   Consult the battery manufacturer's guidelines for handling and potential repair or replacement of batteries with internal cell defects.
