Hello Cahil Quirk,

Thank you for your feedback. We are sorry to hear that you are dissatisfied with the run time of this battery when used in this blower. Higher speeds will drain your battery faster – think about your tasks and how you can vary your speed to conserve battery.
Generally, lower speeds are best for light-duty tasks like blowing leaves off flower beds or clearing dust from a garage. Using lower settings also helps preserve battery power. Higher speed settings are for heavier tasks like blowing wet leaves, clearing debris, or quickly sweeping larger areas. Some models have turbo boost modes, which offer maximum power only while you’re pulling a trigger (this is helpful for stuck-on debris, like a few wet leaves at the bottom of a pile of dry leaves).
To extend your run time, try using the blower setting on a lower speed when high speed is not a requirement, as blowers are considered a high-power draw application which means they do tend to drain the battery quite rapidly in comparison to some other tools. Alternatively additional batteries can be purchased to extend the run time. This unit is compatible with Greenworks 80V batteries (see link below to 80V battery options); please keep in mind, the higher the ampere-hour (AH) rating is, the longer the run time will be.
We would be happy to investigate to see if the runtime you are getting would be considered average, please contact our customer experience team at 1-855-345-3934.7 or by Live chat through the customer contact page located on our website (www.greenworkstools.com)
