Husqvarna Automower Error 012 — Empty Battery

What Does This Error Mean?

Error 012 on a Husqvarna Automower means the battery is empty — the mower could not return to the charger in time. Carry the mower to the charging station, press START, and let it charge fully. Persistent error 012 points to battery wear or a guide wire issue.

Affected Models

  • Husqvarna Automower 305
  • Husqvarna Automower 315
  • Husqvarna Automower 315X
  • Husqvarna Automower 430X
  • Husqvarna Automower 450X

Common Causes

  • Battery has aged and capacity has dropped (typical after 3–5 years)
  • Mower trapped or stuck on terrain so it could not return to charge
  • Guide wire disconnected, preventing the mower from finding the station
  • Schedule too aggressive for lawn size — mower runs longer than battery allows

How to Fix It

  1. Carry the mower to the charging station.

    Pick up the mower (use the carry handle if equipped) and place it directly on the charging contacts at the station. Confirm the contacts engage — the charging LED on the station should light up.

  2. Allow a full charge.

    A fully discharged Automower battery takes 50–80 minutes to recover. Leave the mower on the station until the display shows 100% or the charging LED indicates complete.

  3. Investigate why it could not return.

    Walk the lawn and look for any spot where the mower could have got stuck (a low corner, a step, a tight area between obstacles). Adjust the boundary wire to avoid trap zones.

  4. Check the guide wire.

    The guide wire helps the mower navigate back to the charger from far points. Confirm it is connected at the charging station and not broken. Mowers with a broken guide wire wander and run out of battery.

  5. Consider battery age.

    Husqvarna Automower batteries typically last 3–5 mowing seasons. Repeated error 012 on a mower over 4 years old usually means the battery has aged and needs replacement. Replacement packs cost USD 130–250.

Frequently Asked Questions

How do I know if my Automower battery needs replacement?

If the mower used to complete its schedule but now triggers error 012 frequently, and the lawn size has not changed, the battery has aged. Husqvarna offers battery health checks via the Connect app on supported models.

Can I leave my Automower outside with error 012?

Yes for a few hours, but a fully discharged lithium battery should not be left for days — it can drop below the safe minimum voltage and become non-recoverable. Recover and charge within 24 hours.
