After the end of the mowing season, the robotic lawnmower disappears from the garden for several months. Before storing, the device, battery, and charging station should be properly prepared. Especially with the battery, there is no general percentage that applies to every model: while some manufacturers recommend a medium charge level, others explicitly require a full charge before the winter break.

The frequently mentioned recommendation to store a lithium-ion battery with 40 to 60 percent charge is indeed specified for certain robotic lawnmowers. For example, an instruction manual for a Parkside robotic lawnmower mentions a charge level of 40 to 60 percent during extended storage. Another robotic lawnmower manual also explicitly mentions this range.

However, a universal rule for all robotic lawnmowers cannot be derived from this.

Husqvarna states in a current manual from July 2026 that the Automower should be fully charged before being turned off for winter storage. The current Husqvarna recommendation for winter storage also mentions a full charge before storage.

For ECOVACS, the requirement for the GOAT is also to fully charge the robotic lawnmower before storage and then turn it off.

Therefore, the charge level mentioned in the user manual of the respective model takes precedence.

A robotic lawnmower should not be stored for months with an almost empty battery, unless the manufacturer’s instructions specify otherwise. Some models explicitly warn that complete discharge can damage the battery.

Worx, for example, points out with its Landroid models that a drop in charge to zero percent can damage the battery. For certain devices, the manufacturer therefore recommends regularly recharging the battery during the winter break.

ECOVACS also states in a current manual that extended storage must be considered and that regular recharging is planned for its GOAT.

How often it needs to be checked or recharged also depends on the specific model.

The range of 40 to 60 percent is therefore not fundamentally wrong – but it is a model-dependent recommendation and not a universal rule for robotic mowers.

Anyone who owns a device whose manual specifies this range should prepare the battery accordingly. For other models, however, a full charge may be required. Simply adopting the percentage from another robotic mower can therefore lead to the wrong setting.

For winter storage, the operating manual or the official manufacturer information for the specific device should be checked first.

For the storage location, the manufacturer’s specifications are also more important than general recommendations.

Husqvarna recommends a dry indoor space and temperatures above freezing for winter storage. The detailed manual mentions storage in a garage, shed, or basement, provided the area is dry and frost-free. For certain Automower models, 10 to 15 degrees Celsius are specified as sufficient.

ECOVACS also recommends storing the GOAT in a dry indoor space during winter.

It is therefore crucial not to store the specific device in conditions that contradict the manufacturer’s specifications. Some models have their own temperature ranges, so it is also advisable to check the manual here.

Not only should the robotic lawnmower itself be prepared for winter. Several manufacturers recommend also protecting the charging station and the power supply.

Husqvarna advises storing the charging station or the corresponding components in a dry place and preferably indoors. However, with certain NERA systems, the base plate can remain outdoors.

ECOVACS specifies for the GOAT to separate the power supply and charging station and store them in a dry, well-ventilated place, protected from direct sunlight.

There are also model-dependent differences with Worx: With certain Landroid systems, the charging station can remain outside, but storage indoors is recommended at very low temperatures.

Cleaning is explicitly part of the preparation for the winter break according to various manufacturers.

Husqvarna recommends removing grass clippings and dirt from the robotic lawnmower before storage. The charging contacts of the mower and charging station should also be cleaned.

Worx also advises a thorough cleaning and warns against using pressure washers, cleaning agents, and running water on certain Landroid models.

Before putting it away, the main switch or power supply should also be turned off according to the instructions.

A winter break lasts several months. Whether and how often a battery needs to be checked or recharged during this time is again model-dependent.

Husqvarna points out that most current Automower models do not need to be recharged during storage. However, according to the manufacturer, some older models require recharging every three months.

Worx even recommends a full recharge every two months for certain Landroid models.

Therefore, there is no uniform schedule for all robotic mowers for winter maintenance. The manufacturer’s specifications are decisive.

Anyone taking the robotic mower out of operation for several months should not simply adopt a general battery rule from the internet.

For some devices, 40 to 60 percent is prescribed, while other manufacturers require a full charge. The commonality in the current manufacturer instructions is that the device should be prepared for winter storage, clean, and stored dry or frost-free according to the instructions.

The safest step before winterizing is therefore to take a look at the operating manual of the specific robotic mower.
