This newer version of 40 Amp battery is even better than the original supplied with our mower. We mow over an acre, so one battery was not quite enough. This one is faster charging and lasts about 45 minutes.
Have the 60v 21" mower, does not get 60 minutes of run time using a 5AH battery without the drive-motor, despite the product description saying this is possible with a 4AH. Bought this, and its too long to fit in the compartment with the lid closed.

Hello Owner,
It is unfortunate to hear that the run time is unsatisfactory. The run time of a lawnmower is dependent on the load acting against the unit and fluctuates depending on the height setting, the terrain, grass height, type of grass, whether you are mulching, using self-propelled function etc. - there are so many factors to consider. The run-time of a battery would depend on the load acting on the unit while in use (speed, terrain, unit height, grass height, and density). Please be aware that the more power being used from the lawn mower (i.e. lawn mower speed, terrain, grass height, density, etc.), the faster the battery charge will drain. Here are a few tips to help you extend the run time. 1) Set the mower to the highest cutting height (or 1/3 of the length of grass), mow no more than 1/3 of the total length at a time. 2) Mow in the morning or late afternoon to reduce the heat stress on newly cut grass and ensure that grass is dry. Lastly, while all our 60V batteries can be used interchangeably with our 60V tools. *Some exceptions do apply for the 60V 8.0Ah battery. We would be happy to investigate to see whether your run time would be considered average; please submit an email using the customer contact page on our website or give us a call at 1-888-909-6757 (1-888-90WORKS). All we ask that you have access to the unit so that we can complete troubleshooting with you and gather necessary unit information.
I have three of these batteries now and in spite of getting a good run out each one I am sort of a perfectionist about getting the job done. I have several tools to use them with and when I get started I keep going with the other tools.
The entire lawn mower and the battery cost about the same price as the battery!

Hello ddddddd,
Thank you for your feedback. 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. To learn about other offers please email us directly at info@greenworkstools.com or call our toll-free number at 1-888-909-6757 (1-888-90WORKS) we would be happy to carry on the conversation. Alternately, you could follow us on social media for updates on new units, promotions, and more!
This battery is a monster. It’s a massive step up from the one I had before. I’m able to run all of my equipment with this one without having to recharge.
