The average runtime for a cordless electric lawn mower is between 30 and 60 minutes per charge. However, this can vary significantly depending on factors such as the size and type of lawn, the mowing conditions, and the mower model and battery capacity.
For example, mowing a small, flat lawn in ideal conditions may allow for closer to the maximum possible runtime, while rough terrain, tall grass, or excessive debris can reduce the potential mowing period between charges.
