Estimated runtimes for Tough grass cutting with Husqvarna 525iLK. 

Battery runtime on a single charge depends on several factors such as battery capacity, which kind of machine it powers, the type of application, and external conditions such as ambient temperature and weather. Battery runtime is also influenced by e.g. the battery’s age and health status, the battery’s usage history and remaining capacity, and how the equipment is operated and the power level of the application. The battery runtimes shown are “up to” values based on internal testing of products in energy saving mode, including typical work, basic maintenance, and movement/climbing. These figures are guidelines only and may vary between tasks, settings, and environments, and are not guaranteed to be repeatable in real-world use.
