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.

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.
