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 robotic lawnmower is 
used. A long season or many hours of use a day 
means that the battery must be replaced more 
regularly.

If the operating times for the robotic lawnmower are 
shorter than normal between charges, this indicates 
that the battery is getting old and eventually needs 
replacing. The battery is fine as long as the robotic 
lawnmower maintains a well-cut lawn.
