This behavior indicates that both the mowing duration and the time spent charging are reduced. This can be normal in high ambient temperatures, but can also signal a problem with the battery's capacity.
Click steps to track your progress.
Note if the ambient temperature is significantly high (above 25 °C), as this can reduce operating times.
Perform a battery test to determine the battery's current capacity.
If the battery capacity is low, consider replacing the battery (see page 96).
Ensure the mower is operating in its intended conditions, avoiding extreme heat if possible.
Monitor the mower's performance over several cycles to confirm if it's a persistent issue.
