There’s an owners manual. There are instructions about battery charging. I don’t know what would need servicing on the unit since there’s no fuels being used.

20 in. 40-Volt MAX Lithium-Ion Cordless Walk Behind Push Lawn Mower - Two 2.5 Ah Batteries/Charger Included is rated 3.9 out of 5 by 121.
Rated 5 out of 5 by from Cordless electric mower (Black&Decker) Mower is well-built and does a great cutting job on our lawn with much less noise, leaving no tracks like our gas mower did. Mower is light and easy to push. Differences with using a gas mower: we don't have a large lawn (about 2-3000 sqft) but I have to move quickly to get the mowing done before both batteries are discharged. Note that we are only using the mower in mulching mode which is probably drawing more power. We used to use about 3/4 of the gas tank on the gas mower (also a mulching mower) to complete mowing. You will need to mow more frequently. If the grass gets too long, it's a heavier load on the battery, and you won't get as far with mowing. If grass gets too high, the mower will just quit , and you will have to turn it on again. In that case, you can adjust the mower one notch higher for mowing height. Also, don't expect to have the first battery recharged by the time the second one gets discharged. Charging time is 2-3 hrs. We are on the borderline of needing to get a 3rd battery, but haven't yet.

Rated 1 out of 5 by from Frustrating & not Efficient I traded in an older battery Black and Decker mower that had a big battery in it. Don't remember the specifics. That mower was heavier to push but I could get my entire lawn done with one charge and it did not matter how thick the grass was. I bought this mower in 2016 and it was a poor purchase. I have to have it set at level 5 to cut my lawn and can only get my front yard done with the two batteries. So here I am looking to buy a 3rd battery,but after looking at the reviews I am going to pass and try to sell it. It is light weight but I can't mulch or bag or I would only get half my front yard done. As it is I have to mow two different times or two different days to get my whole yard done. Not EFFICIENT at all.

Rated 4 out of 5 by from Light and easy to manouevre Yes! I am glad I bought this model. Very Easy to use.
Date published: 2019-08-12
Rated 5 out of 5 by from Powerful, Lightweight I'm not quite sure where to begin. There are a lot of great things to say about this mower, I hope I don't leave anything out. First off, they include everything you need in the box. You have three choices for discharge: side, mulch, or rear bagging. The mower easily switches between the three. Second, the batteries charge up fairly quickly. You get two batteries and a charger. You can charge one and still use the mower. The battery pack lasts for about 20 minutes of continuous mowing. Batteries install and remove with ease. Third is the easy adjusting cut height. One lever controls all wheels. Simple! Fourth would be storage for the extra battery. Fifth would be the safety key feature to prevent any accidental usage by children. Sixth would be the ease of operation. The mower is lightweight which makes it easy to maneuver and push. Seventh would be the ease to adjust the handle height. There are orange levers on the handles that remove tension and allow you adjust for height. These are the same quick releases that allow the handles to fold for storage. Eighth is the collapsing handles that fold down for easy storage. this unit can be stored horizontally or hung vertically on the wall. This mower is just plain simple and easy to use. I don't know why I waited this long to try one. I added a video to show the use of the mower and how easy it is to maneuver around objects. The video sound makes the mower out to be noisy. It is fairly quiet while in operation.

Rated 4 out of 5 by from Check batteries first Before you begin to un-box the mower, take the batteries out and check to see if they can take a charge. If one is defective, as mine was, Home Depot will replace the whole mower. No, not just the battery. So learn from me. The refund for the defective battery was 5% of my purchase price...around $19.00, not nearly the almost $100 to purchase a close to replacement battery. The 40V 2.5AH batteries that come with the mower can not be purchased separately. The closest would be a 40V 2.0AH battery which is not available from Home Depot, but Amazon. I love the mower. It is much easier to handle than the self-propelled mower it replaces. It was extremely easy to put together since not much needed to be done. And the one battery that worked lasted long enough to do my back yard.

Rated 5 out of 5 by from I have had this mower for one month and I love it. It is so light weight and easy to use I mow m... I have had this mower for one month and I love it. It is so light weight and easy to use I mow my lawn every few days. I have a small front yard and when it starts to look uneven I pull out the mower and give it a quick once over. There is a safety key you put in, push the button and pull on the safety bar and it starts running. Two days ago my battery went dead and I just reached down and put in the second battery that comes with the mower. The mower went from what sounded like a full charge to stopped. I like this feature because I don't have to worry about the grass not getting cut clean because of a low battery. The other thing I like is the blade cutting path is outside of the wheels. This allows you to get right next to the fence, bricks and house.

Rated 5 out of 5 by from So far, so good... I am a 66 year old female who maintains her own landscape. This mower was easy to assemble, is light enough to carry up and down 5 steps (batteries removed) and cuts the grass very well. My grass was overgrown when I first used the mower and the mower worked just fine. I did go slow to get used to it and so one battery lasted only about 30 minutes. I've since used it two times and between both batteries there is more than enough juice to finish. Not exactly sure of the yard measurements but it's an average size. My only "con" is that it really doesn't get up to the edge as the booklet states. Guess I'll look for a battery-operated edger.

Rated 4 out of 5 by from Convenient and Light Weight The Black + Decker: 20 in. 40-Volt Max Li-Ion Cordless Electric mower provides an average cut with no fuss. It is extremely light weight because much of the mower is plastic. I understand why, to enable the operator to push the mower with relative ease, however, I always question the longevity that plastic will provide verse steel. The 2- 40-Volt Li-Ion batteries last about 20 minutes each. Many reviewers call the second battery a spare, but I personally don't know anyone that has a lawn so small that it only takes 20 minutes to cut it from beginning to end. I call the second battery necessary because the first battery is going to loose power before you are done cutting the lawn. Plus, as the mower and batteries cut older, the run time is going to be less and less. The Black + Decker: 20 in. 40-Volt Max Li-Ion Cordless Electric mower does a decent job at cutting the grass in any of the 3 modes that the operator can choose: discharge, mulch, or bag. So, if you have a very small yard, approximately 1/4 acre or less, then the Black + Decker: 20 in. 40-Volt Max Li-Ion Cordless Electric mower might be a great choice for you.
