A:Answer Hello Mokeman - Thank you for the question! 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 Greenworks 80V (730 CFM) blower can expect up to 30 minutes of runtime with included 2.5 Ah battery (on low speed). When used at high speed, approximately 10-15 minutes is an average run time for the supplied 2.5 Ah battery as this unit does draw quite a bit of power on high, however, the run time can be extended by using it at a lower speed. The string trimmer will provide up to 10-15 minutes runtime with a 2.52Ah battery. Alternatively, additional batteries can be purchased to extend the run time. This unit is compatible with Greenworks 80V batteries. The higher the ampere-hour (AH) rating is, the longer the run time will be.
