Empty battery
Husqvarna Empty battery on robot mower: ran flat outside base
Risk level
Low
Usually safe to check without specialist tools.
Urgency
Medium
Quick answer
The Automower ran out of charge away from its base. Husqvarna lists four causes: it cannot find the station, the battery is at the end of its life, the station antenna is damaged or the charging plates are corroded. Bring it to the station and check those points in order.
Safety first
Stop and check this first
- Unplug the power supply from the outlet before cleaning the charging station and keep high-pressure or running water off it, as Husqvarna instructs.
- Do not open the mower to pull out the battery: Husqvarna reserves removal for disposal and taking off the seal voids the warranty.
Safe checks you can perform
- Carry the mower to the station and watch it charge
- Read the charging station indicator lamp
- Clean the charging plates and check the guide wire
Leave these tasks to a qualified professional
- Do not attempt this professional task: Battery replacement by authorized service

What a technician must be able to justify
Technician visit
These are the steps they must carry out and show you. Tick them as they work: if steps are skipped, do not accept a part swap.
These are not instructions for opening or handling the equipment yourself. They are the checks that should support a technical conclusion.
Battery replacement by authorized service
What they doWhen the run time is clearly shorter than before, the manual says to replace the battery; full removal breaks a warranty seal, so leave it to service.
They must show youthe capacity measurement or battery state of health before the swap.
In writingthe part number of the original battery fitted, the price and the warranty on the new battery.
Charging station check by Husqvarna
What they doWith a red lamp on the station, the manual says to contact Husqvarna customer service, as there may be antenna interference or a circuit board or power fault.
They must show youthe station signal test and the condition of the power supply.
In writingthe fault found in the station, the parts replaced and the warranty applied.
Before accepting a part or repair
Nothing has been shown yet. Do not accept a part swap based on the code alone.
Follow these steps
Note: Follow the documented order. An error code identifies the affected system, but it does not prove by itself which part has failed.
Carry the mower to the station and watch it charge
- Who:
- you, with the mower switched off as the manual describes.
- How:
- push STOP, switch it off with a three second press on ON/OFF, carry it by the handle with the blade disc away from you and set it in the station. After a deep discharge Husqvarna warns that charging can take a long time: leave it for up to 24 hours before trying to set it to ON.
- Result that matters:
- the mower charging in the station and able to be set to ON again.
- If it charges and starts normally:
- work out why it did not return on its own with the next checks.
- If after 24 hours it still cannot be switched on:
- the manual says to contact your authorized service technician.
- Evidence to keep:
- the time you put it on charge and whether it powered up.

Read the charging station indicator lamp
- Who:
- you, standing next to the station.
- How:
- note the colour: solid or flashing green means a correct installation, flashing blue points to the boundary wire, flashing red to antenna interference and solid red to a circuit board or power supply fault that an authorized service technician must correct.
- Result that matters:
- ruling a station problem in or out before blaming the battery.
- If the lamp is green:
- the station is signalling properly and the cause lies in the return trip, the plates or the battery.
- If the lamp is red, solid or flashing:
- leave the station as it is and contact Husqvarna customer service.
- Evidence to keep:
- a photo or short video of the station lamp.

Clean the charging plates and check the guide wire
- Who:
- you, wearing gloves, with the station power supply unplugged from the outlet.
- How:
- with the mower off, rub the charging plates on the mower and the contact plates on the station with fine grade emery cloth, and clear grass or twigs from the station. Then follow the guide wire from the station and confirm it is connected and laid as the installation section shows.
- Result that matters:
- clean contacts and a guide wire the mower can follow back to charge.
- If the plates had corrosion or dirt:
- after cleaning, run one full mowing and charging cycle.
- If everything is clean and the mower still runs flat:
- consider whether its run time has dropped noticeably.
- Evidence to keep:
- before and after photos of the plates and notes on the guide wire route.

What it means
The Automower 405X/415X operator's manual (page 37) lists "Empty battery" among the fault messages. The causes it gives are that the product cannot find the charging station, that the battery is at the end of its life cycle, that the charging station antenna is damaged, or that the charging plates on the mower or the contact plates on the station are corroded. Seeing this message is not enough to conclude that the battery is worn out or that any part is faulty: rule out the guide wire and the station first.
