What’s the lifetime of the battery?

The battery is maintenance-free but has a limited life span of 2 to 4 years. Battery life is dependent on the length of the season and how many hours a day the GARDENA Robotic Lawnmower R40Li is used. A long season or many hours of use a day means that the battery must be replaced more regularly.

What’s the lifetime of the blades?

The lifetime of the blades varies immensely and depends for instance on:

  • Operating time and size of the working area.
  • Type of grass.
  • Type of soil.
  • The presence of objects such as cones, windfalls, toys, tools, stones, roots and the like. The normal life is 1 to 3 months when used in areas more than 300 m² in size and longer for smaller areas. You can easily replace the blades by yourself.

Do I need to store the Robotic Lawnmower inside during winter?

Yes. Before putting your GARDENA Robotic Lawnmower away for the winter it should be cleaned and wiped dry and then stored in dry and frost-free conditions. We also recommend that the charging station is stored indoors over the winter. The loop wire installation can remain in the lawn.

How do I maintain the GARDENA Robotic Lawnmower to keep it in the best condition?

Replacing blades regularly is vital to maintain an excellent cutting result. Now and then, depending on your lawn size, you should spend a few minutes cleaning grass from the wheels and chassis as well as from the charging station.

How do I replace the blades and what tool do I need?

You can replace the three lightweight blades in five minutes using a regular screwdriver. Make sure you also change the screws.

How do I replace the battery?

If the operating times for the mower are shorter than normal between charges, this indicates that the battery is getting old and eventually needs replacing.

Follow the instructions in the Operator’s Manual for how to replace the battery.
