Rated 5 out of 5 by from I love Greenworks tools I have a whole set of 40v tools and love using them! To get my lawn done the mower uses 2 batteries so I got this as an extra. The usb charge port is a nice addition particularly since I have all these tools at our cabin in the Adirondacks where electric power isn't always stable. If power goes out I can always rely on this battery for backup power for our small devices. And the battery holds a charge for a long time! We can be gone for months and it is still charged and ready to go.

Rated 5 out of 5 by from CAN'T GO WRONG WITH THIS ONE. LIVED UP TO MY EXPECTATIONS. I HAVE OWNED SEVERAL GREENWORKS TOOLS FOR 6 YEARS. GREAT PRICE. POWERS MY MOWER WELL AND HAS GOOD LIFE. USB PORT IS VERY HANDY FOR PHONE CHARGING WHEN HANGING OUT BY THE POOL OR CAMPING.

Rated 5 out of 5 by from A Great Battery A great Battery! I have been using it in a twin blade lawn mower. It works as well as the 40V 4ah battery. The battery does not seem to get as hot as the other batteries I have, and has a good run time.
