Possible Causes

Aged battery pack, Cold ambient temperature, High cutting load due to long grass, Battery not fully charging due to dirty contacts

How to Fix / Troubleshooting

Safety first: Keep the mower docked while inspecting charging components.

  • Clean contacts: Wipe the charging contacts on both the mower and station with a dry cloth to ensure good electrical connection.
  • Reduce load: Raise the cutting height and pre‑cut very long grass with a conventional mower to reduce current draw.
  • Temperature considerations: In cold weather, expect shorter runtimes. Store the mower and station in a more temperate environment if possible.
  • Battery replacement: If the mower is several years old and runtime remains poor, replace the internal battery pack with a Flymo‑approved replacement.
