Extended Battery Life

Really impressed with the extra time this battery gives every tool weedeater, mower and hedge trimmer . Thanks!!!

Fast Eddie Northland
more power is good

this can run the 21"mower for just on 30 minutes without using the self drive if you use that and you have just over 15 minutes run time - have used 4 times & its holding the charge good.

extra grunt and power for my other greenworks tools

love greenworks tools. the interchangeable system is powerful and easy to use. the extra battery for swapping out when needed so i can get all the jobs done in the garden at the same time. no more petrol/oil, fumes and noise !
