Might be a great battery, but, if you plan on using it in the push mower, which is the only reason I bought it, be prepared to cut up your mower to make it fit. Too tall, too wide, and a lot heavier than the standard batteries. I can only upload one image for some reason, but you will have to cut the lower mount where the battery slides into for operation, but also cut the lid, so it can close. I will seal these areas back up with fiberglass and plastic, then paint and re add the logos

    Holy Runtime
    [This review was collected as part of a promotion.] I got this battery a few weeks ago and it has made my runtime on my RY401130 double! This is an awesome battery and I would recommend it to everyone.

      best accessory
      This battery weighs about 4.4 lbs judging from my scale at my home. It is perfect for my RYOBI 40-Volt tools! I can mow my entire yard, more than half of acre, with just this battery. My neighbors are coming over to see the mower and I tell them they should get this battery too because its a game changer. this also fits in my ryobi string trimmer and blower but i dont really need that much runtime on those.

        Last a good long time
        [This review was collected as part of a promotion.] This battery I got with the purchase of the leaf vacuum and leaf shredding. Bag is big enough to do a large area before you have to empty it.

              Great upgrade to my power station
              [This review was collected as part of a promotion.] Runs a long time on a charge and charges fast. I will buy 2 more in the near future. These work a long time in my other Ryobi tools. Buy it you won't regret it!

                  All my tools are Ryobi and I like the versatility of the batteries which you can use for different kinds of tools. This specific battery is just a back up for my Ryobi lawnmower. It’s great!
