Mower does not charge fully; it leaves the station with low runtime even after long docking.

Safety first: Unplug the power supply from the wall before cleaning contacts.

• Clean contacts: Use a dry cloth or fine abrasive pad to gently clean the metal charging contacts on both the mower and station.
• Check alignment: Ensure the mower sits fully into the station with both contacts touching firmly.
• Inspect power supply: Confirm the Gardena adapter is the correct model and not overheating. Replace if suspect.
• Evaluate battery age: If the mower is several years old, consider replacing the battery pack.

After cleaning and any replacements, monitor charge time and runtime to confirm improvement.
