The Ryobi Lithium+ Mowers redefine the 18-Volt category by delivering the power, run time and performance you’d expect from higher voltage lines, while still offering the versatility of the ONE+ system. The Ryobi 16 in. Hybrid 18-Volt Lithium+ Lawn Mower is the first dual power mower in the industry. Its unique design allows you to switch from the included ONE+ 4.0 Ah lithium-ion battery to an extension cord to ensure that you will never run out of power. This mower has two battery ports, giving you the option of using a second ONE+ battery to increase the cordless run time. With its simple push button start and single point height adjustment, this mower makes lawn care easier than ever before. Its lightweight and compact design makes this mower ideal for small yards and maneuvering in tight spaces. This mower also has a 2-in-1 mulching or bagging system, allowing you to get the job done quickly and just the way you like. The foldable handle has quick-release knobs, making it simple for those with limited storage to prepare for use and put up. For additional convenience, this lightweight, compact mower has a top-mounted handle, making it easy to carry from one place to another. The 18-Volt Lithium+ battery and charger are compatible with any of the Ryobi 18-Volt ONE+ tools. Backed by a 3-year warranty.

16" 18V ONE+ Hybrid Walk Behind Push Lawn Mower - Two 4.0 Ah Batteries/Charger Included is rated 4.7 out of 5 by 78.
Rated 1 out of 5 by from I wouldn't recommend this lawnmower to anyone. Against my wishes my wife bought this electric lawn mower. I personally go for the gas versions because they last a lot longer. My biggest problem is that the batteries don't last that long. I've watch countless videos on this product. Both from Ryobi & buy people testing them out. And I don't know how Ryobi is getting 40 mins out if this lawn mower. But all the YouTube reviews along with myself are only getting like 10- 12 mins and then the batteries have to be recharged. As you see the from the pictures of my lawn. It will take me all day and maybe 5 -7 charges just to finish my whole lawn. As soon as I can get a better lawn mower this lawn mower is going in the garbage along with these horrible batteries. I will never buy another Ryobi product seeing the major disappointments I had with this one.

Rated 4 out of 5 by from The Silent Mow Bought this for the new place and it's great. Glad it comes with two batteries since we did the first pass a bit low and it was strenuous on the first battery. Would highly recommend not trying to take on big patches of weeds on the low height settings.

Rated 5 out of 5 by from Makes my gas mower obsolete I just bought this mower and love it!! I can go up and down the steps in the backyard without killing my back. It is so quite and efficient. My wife even loves it.

Rated 5 out of 5 by from Light and easy to push I bought this as a replacement for a 20-year-old gas powered Honda that was self-propelled and very heavy for me. That has needed a lot of work. I am hoping that this mower Will make mowing a lot easier for me. I have other Ryobi products that you use the 18 V batteries so it’s going to be very easy to enter change them. I have been able to push it up and down the hill with very little effort. The mulching device works great! I will never use the bag but it’s nice to have in case I need it for leaves or something.

Rated 5 out of 5 by from Easy to use, cuts very well! I did not get a free lawnmower. Am a single gal who had it with gas and oil and pulling a string. This Ryobi is wonderful! Cut the grass perfectly and easy to start.

Rated 4 out of 5 by from Works Great It bought it a couple months ago and it works really well, very quiet compared to traditional lane mowers which I like. It does go through batteries pretty quick so make sure you have spare ones on hand. It can take 2 at a time.

Rated 4 out of 5 by from Hybrid is key I only have 3000 sq ft of lawn to mow and the batteries only allow for me to do either the front or the back plus a little of the other. the Hybrid is key as i can just plug it in to finish the job. I'm a little disappointed the batteries don't take care of the whole job but it cuts well, is lightweight, and overall a very good product.
