Greenworks 24V 4Ah USB Battery, BAG709

I bought two additional batteries to have on hand for my battery powered lawn mower. They have a lot of power. I use two in my lawnmower and it cuts a large sized yard. Two batteries will give you 45 minutes of run time. If grass is really tall you won't get that same run time or if you are mulching lots of things in yard, like pinecones or small sticks. Best to have extra batteries on hand because it takes hours to recharge batteries fully. You can check to see how much charge is in each battery by the gauge on the battery. These are multi-use batteries. They have UBS port so can be used as a power bank also. They are a little costly, but they are large batteries. No trouble charging and they discharge very slowly. After 5 months when the need to start using my lawnmower again, the batteries didn't need to be charged they were still fully charged.

I use this as a second battery for my mower. It works as intended.

Love the usb charger and long lasting

I'm quite happy I bought this as it keeps by leaf blower running much longer. I used to run out of charger before I ran out of leafs to blow, but now I can finish the job before I need to swap or recharge. A good addition to the tool kit.

Had to order 2 additional batteries as run time is less than what is stated in lawn mower information.
