Low battery voltage

Low battery voltage — No F-signal or N-signal from charging station

husqvarna · Automower Technical Manual

What does Low battery voltage mean?

The Automower cannot find the charging station because there is no F-signal (remote) or N-signal (near) from the charging station. This will eventually lead to the mower stopping and displaying a 'Low battery voltage' message.

Common Causes

  • No F-signal from the charging station (large coil in charging station plate).
  • No N-signal from the charging station (two small coils in charging station plate).
