Hello gbob9657,

Thank you for your feedback. We are glad to read that overall, you have been enjoying the 60v platform. Your run time sounds average when using this battery with the blower. While this product does have capabilities of running up to 45 minutes, this is essentially at a very low speed. When used at high speed, approximately 20 minutes in this blower is an average run time for the supplied 2.5Ah battery as this unit does draw quite a bit of power on high. The run time can be extended by using the product at a lower speed when higher speeds are not necessary. Blowers are considered a high-power draw application. Additional batteries can be purchased to extend the run time. This unit is compatible with all Greenworks 60V batteries. The higher the ampere-hour (AH) rating is, the longer the run time will be.
Currently out of stock on many of 60V batteries, as we have some delays due to the current pandemic (Covid-19) however, we are expecting them to come in soon. They can be viewed using the following shared link https://www.greenworkstools.com/shop-by-voltage?cat=49. In the meantime, you may enter your email into the appropriate field on the battery page(s) so that you can be notified as soon as the stock has been replenished.
