A Good Amount of Power.
This is for my HART HLPM02 20 inch 40 Volt Self Propelled Lawn Mower. I live in Florida, and have used the mower 3 or 4 times now and the battery has performed well, lasting between 30 and 45 minutes. I have two areas to cut, one hilly and the other flat, of about 2500 sq ft each. I'm very satisfied with the power that this battery supplies. Recharged in a few hours.
We are so glad you are enjoying your mower, thanks for letting us know!

they got it where when it charges all the way it stops charging.

Great Battey
I am an older single woman looking to make my yard work easier. I decided to go electric to avoid hauling gas in my car not to mention pulling cords to start. I purchased a Hart 40v 5amp lawnmower and it is amazing. I needed a backup battery for my large yard and this does the trick. I love that it has a button that tells you how much charge you have left and you can use it for any Hart 40v tool.
