Longer than my other 80 Volt Batteries but it does fit all my Greenworks tools, Lawn Mower, snow blower, leaf blower, hedger and trimmer. Less than an hour of run time on the mower.
Getting service is going to be a problem as been on hole over 39 minutes to tell them we are returning the 2 item we purchased because of battery weigh and batters are all different volts. Bought 2 different items and got 3 different batteries. Checked price of batteries and they are outrageous in price. Some take 2 hours to charge and they only give you one battery on some items.

Hello Fredk44
We are sorry to hear you are dissatisfied with the charge time for this battery. As advertised Greenworks 80V ~ 4Ah rapidly charges to full capacity in just 60 minutes. Batteries are the costliest items to manufacture and ship in any kit. Full kits including a tool, battery, and charger are priced affordably so that consumers can begin building that line of tools and move forward purchasing tool-only units. When you purchase batteries on their own, it is more notable the cost that they carry. We apologize if this is of any inconvenience to you. Greenworks provides a 30-Day money back guarantee on all direct purchases, less shipping and handling, this information can be found on our Return Policy page, please click link HERE http://www.greenworkstools.com/latest/return-policy to view the full return policy.
The capacity of this battery has been fantastic! The only thing I would mention is that it is kind of heavy, so it is better for tools on wheels rather than ones you have to carry.
I have the 80V mower and it does a excellent job. The battery stays charged for my entree 1/3 of a acre. All of my neighbors rave about how quiet it is and a few have purchased a Greenworks mower as well.
