Hello there,

Thank you for your review. We are sorry to hear that you are not completely satisfied with the run time that you are receiving. Please know that there are many factors that can affect the run time. The run time of a lawnmower is dependent on the load acting against the unit and fluctuates depending on the height setting, the terrain, grass height, type of grass, whether you are mulching, etc - there are so many factors to consider. The run-time of a battery would depend on the load acting on the unit while in use (speed, terrain, unit height, grass height, and density). Please be aware that the more power being used from the lawnmower (i.e. lawnmower speed, terrain, grass height, density, etc.), the faster the battery charge will drain. Here are a few tips to help you extend the run time! 1) Set the mower to the highest cutting height (or 1/3 of the length of grass), mow no more than 1/3 of the total length at a time. 2) Mow in the morning or late afternoon to reduce the heat stress on newly cut grass and ensure that grass is dry. 3) Only use the self-propelled feature when needed. We hope these tips will help you with the issue you have encountered, however, if they do not please kindly give us a call at 1-888-909-6757 (1-888-90WORKS).
