Extra battery

Not cheap, but pleased I got the extra battery

GreenworksG-MAX40v6.0ah li-ion Battery

sure glad I brought this

Guisey Auckland
replacement battery

having a quarter acre section mostly in lawns and raised garden beds with fruit trees etc....i found that the 4ah batteries (i have2) were not quite enough to cover the whole section with the mower and weed eating as well...but have since found the 6ah battery to be able to trim all the lawns with the mower and still have enough power (1 light out of 4)....which then leaves my other batteries for the weed eating etc

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.

Bob Manawatu
Real staying power

Great battery. Unbelievable stamina…,keeps on going and going. Not too heavy either

Greenworks G-Max battery

Great gutsy battery, does the job and relatively quick recharge. I use it on the Greenwood blower vac and I can get the whole section done on one charge.
