Display shows “Battery problem,” and the mower stops, refuses to start, or has very short mowing cycles.

Safety first: Turn the main switch off and remove the mower from the charging station.

• Temperature check: If the mower or battery area feels very hot or very cold, allow it to reach room temperature before further testing. Husqvarna batteries have optimal temperature ranges.
• Inspect battery compartment: Open the battery cover and ensure the pack is securely mounted and the connector is fully engaged.
• Runtime observation: Fully charge the mower, then observe how long it mows before returning to charge. If the runtime is significantly below the specification, the battery is likely worn.
• Replace battery pack: Install a new Husqvarna-approved battery pack with the correct voltage and capacity for your model. Follow the manual for removal and installation steps.
• Reset and test: After replacement, perform a restart (main switch off/on) and run a full mowing cycle to confirm the error is cleared.
