Answer:
The battery’s lifespan depends on several factors, including how many hours you use it, how hard the mower works, the conditions where you mow (e.g., heat, humidity, terrain), and how well you store it when not in use.
If you notice a significant drop in runtime—such as the mower stopping much sooner than usual—it may be time to replace the battery. Please contact your local dealer or the RoboRock Customer Service team for assistance.

Note: Charging may fail if the mower is placed in an environment that’s extremely hot (above 40°C / 104°F) or extremely cold (below 0°C / 32°F). For best results, move the mower to a room-temperature location (ideally between 10°C–30°C / 50°F–86°F) before charging.
