Hello SabsBurch,

Thank you for taking the time to share your experience.
We are sorry to hear that the unit has not fully met your expectations. The overall battery life is dependent on many factors such as where they have been stored, charged, and handled. When the battery will not be in use, we suggest storing it indoors, in a cool dry area - away from direct sunlight. Leave the charger unplugged and the battery disconnected from the charger unless it needs charging. It is recommended to store the battery with a full charge, and if it is being stored for a period where no use is expected, to check on the charge every couple of months. If you notice the charge has dropped, we advise charging the battery back up to full before returning it to its safe storage place. Following these steps will ensure you receive the most of the battery life. Runtimes can vary depending on a few factors, including but not limited to if the self-propel feature is used throughout the entire cut, grass texture and consistency, cutting height, and lawn size. If you wish to address your concerns directly with one of our Product Experts, please contact us by chatbot through the customer contact page located on our website on www.greenworkstools.comor call Greenworks Pro toll-free helpline at 1-855-345-3934.
