Good Mower, Bad Batteries.
I have had my mower for a few months now. The mower itself has lots of power and is good but the batteries that come with are not of adequate size. Also only one charger for the two batteries and not even a fast charger. I would not recommend unless you are willing to purchase extra batteries or already have extra 5ah or higher batteries. It takes me three charges to do an average size lot in a trailer court with the batteries provided.

Works great for the job at hand
Second time mowing, can finish full yard on the 5 amp hours batteries. City lot; lots of berms so this isn't a very large yard. Noise level is much better than gas mower this replaced, neighbor commented same. Wish that they put a little more engineering into the top plastic battery hatch cover. When closed and rolling over bumpy areas the rattling noise it makes is disappointing. Also wish the batteries that came with it said 2019 versus the 2018 batteries that I received.

Solid mower
I bought a new house and needed a mower. I operate an equipment rental store, so I know tools. This holds up. The batteries run out in about an hour of mowing.

Fathers Day gift, works great.
6-2019, Fathers Day gift replaced my old gas mower and Stihl 2 stroke trimmer. Was concerned about the battery life in the other reviews, but decided to give it a try as I have other DeWalt tools. Yard measures about 35x35, or say two 30'x20' sections, equaling about 1200sq'. (This is about 3/100ths of an acre (.027acre). Suburban home with typical front and back yard. For reference, 1/4 acre (.25) = 10,980sq' or about 100'x100' lawn).

I don't know what it is rated for, but with the 2 supplied 20v 5ah batteries in it, my son mowed the lawn in 20 minutes, and still had 2 battery lights left out of 3, indicating it only used 1/3rd of the capacity to do a typical home lawn. It completely filled the bag, FULL, and emptied like a breeze, where my old one was always tough to empty. With batteries, it weighs about the same as my Craftsman gas mower, but pushes easily.

Quiet, no gas or oil, handle folds easily, and I love that you can store it upright, on end, as it is made to stand up.

In addition to the mower, the new 20v Dewalt trimmer is lighter than my gas Stihl, no blue smoke and oil, and trims the whole yard and still shows a near FULL Charge. It seems easier to handle and more precise near the flowers, etc., so the wife loves it if I don't cut the flowers off...

Overall, presently surprised, hopefully the batteries will last for years like my other Dewalt tools have, only time will tell.

Believe for the typical suburban homeowner, the supplied 20v 5ah batteries will be more than enough, again, we had 2 battery bars left out of 3 when finished mowing the front and back yard, about 20 minutes and 1 week growth of lawn after rain that week so it was pretty long. Filled large bag catcher completely.

Listed my trusty gas mower, and pro grade Stihl trimmer on craigslist and sold in 1 day, so no looking back now...:)

Perfect for my small city lot
I was already invested in the DeWalt 20v battery system, so this lawnmower was a natural choice. The bagging and mulching systems work just as well as my old gas Honda. The mower is light enough that it does not need to be self-propelled. It folds up neatly so I can carry it downstairs for storage in the corner of my basement. The two 5ah batteries are just sufficient to mow my small 5600 square-foot (0.13 acre lot in a single charge I love that they are interchangeable with my other tools. I do think DeWalt ought to include larger batteries. My lot is tiny, but if it was any larger, I would not be able to mow in a single charge.

Buyer beware!
There is nothing wrong with the mower itself, it is a decent and easy to use piece of equipment.
The problem is with the battery system that DeWalt decided to use for this mower.
Why a company would include 2 batteries and only 1 battery-at-a-time charger is ridiculous! This mower charging system is NOT user friendly. It takes about 1 hour to recharge a battery X 2 batteries, the user is down 2 hours from mowing. Not only that, the 5 AH run time is only about 20 min and boom, the user is back in the recharging cycle. Unbelievable!
I returned my machine to the retailer from which I purchased the unit.
I am looking at competitors brands now!
Stay away from this mower.

Batteries and charger
This mower does a get job, mowing. However the batteries do not discharge equally and the mower comes with a single battery charger. I have a cordless miter saw that came with a dual battery charger, so I know that it is available. I have to charge one battery overnight, and then switch them out for another day. This is very inconvenient, as it needs to be done every week. A dual charge would be a great improvement. Better yet, an option to charge the batteries in the mower. At a minimum, the mower should come with a set of back up batteries. If I run out of juice before completing the lawn, I have to wait two days, to recharge, to finish the job. I am very disappointed with DeWalt for cutting corners on this. I hope this policy is not going to be DeWalts new business plan.

Good mower but has limitations
I bought one of these to use on my customers smaller lawns, which it does a great job, I use it with 2 9ah batteries and find this is enough for 3 small lawns, providing the grass isn't too long or too wet. I usually start the season using my petrol mower and maintain it the rest of the year using the dewalt. use it approx 3 times a week throughout the season so far no issues

Great - not so Great
I bought this mower a few months ago and have had a chance to use it on grass and in leaves (mostly maple. I so wanted to give this a 5 star review for the great things I like about it. But, before buying this, I did read all of the reviews and, unfortunately, I am finding the same limitations others found (poor run time, an unacceptable charger). I have a small city lot and a pretty sizable collection of other Dewalt 20v tools/batteries and chargers to supplement that which was provided with the mower. So, for me, this means these limitation are of a marginal concern. Overall, I am pleased with the mower and the run time on the 2 - 5 amp-hr batteries is sufficient to mow my lawn on a single charge (about a half hour), but is insufficient if I am dealing with fall leaves. And, I find that packaging this mower with only the single slot slow charger to be unacceptable, especially considering that Dewalt has a 2 fast chargers that could have been packaged with it. Hence, a large part of my 3 star rating.
Here’s what I have found to date:
Pros: The mower, other than the noted limitations, is basically well thought out, well designed, and built to the high end level I expect from Dewalt. It has nice features such as an easy to fold handle that doubles as part of the support for storing it on-end and the single lever height adjustment, which I use multiple times while mowing. The housing and handle are metal and quite substantial. Use of plastic seems to be appropriately done. I have not found places where I would wish they hadn’t used plastic. The section of the height adjustment mechanism for the front wheels includes a spring that allows for front wheel movement which absorb some of the shock of pushing the mower over my rough lawn. The housing and blade design does well at mulching and, with the bag attached, does well at picking up leaves, cutting them up and stuffing them in the bag. It does well at fully filling the bag, which is good as the bag is a bit on the small size. The mower weight is reasonable given its quite substantial metal housing. Its wheels are sufficiently large to all it to easily roll over my lawn (they are larger than those on my gas mower). The motor power, when fully up to speed, is good and sufficient enough to handle cutting up and bagging the maple leaves covering my back lawn. However, note that the mower has very little starting torque and it struggles to get going if there is cut grass and/or leaves in the housing and around the blade. The 20” cut path is nice and better than some other brands. No gas, oil or cords to deal with and, of course, the batteries are usable in other Dewalt cordless tools, if you have them.
Cons: The charger. Dewalt included their 2 amp slow charger (DCB112) for charging 2 - 5 amp-hr batteries. That is 5 hrs of charging, or more if you can’t catch the first battery right at the end of its charge cycle. With 2 batteries it is not even possible to charge these overnight and have them ready to go the next day. I find this to be unacceptable, especially considering that Dewalt has 2 other fast chargers that could have been included (DCB115, single slot [not really desirable either], or DCB102, 2 slot). Even on my small lawn the run time with the 2 - 5 amp-hr batteries is marginal. The location of the cord from the end of the handle to the motor is such that it gets pinched in lower hinge of the handle. That pinch point is scissor-like and, eventually, is going to cut the cord. The rear discharge option is useless in all but dry grass as it easily clogs.
Observations: While I really like the single handle height adjustment, the lever for this can easily get caught on bushes or the like, and change settings. Sharpen the blade, which is not very sharp out of the box, and keep it sharp. This will improve run time a bit, along with mulching and cutting up leaves. The safety handle is very sensitive to how it is held. I have had the motor trip off at times when I thought I had a good grip on it. 2 hands work the best.
Conclusion: This mower suits my needs; my “Pros” are what I like about it and there is not much for me not to like. I would recommend it, but with the reservation that the person be someone with other Dewalt cordless tools, and has only a small lawn.
For Dewalt: This could easily be a 4 or 5 star mower but for the charger and run time. This mower commands a premium price against other brands. For that premium price, you have the charger on the shelf that should be included; that is the 2 slot DCB102 high speed charger. As for run time, that could be addressed by offering a trade-in option of the 2 - 5 amp-hr batteries for a heavily discounted priced pair of 9 amp-hr or larger batteries or package the mower with different battery options. Finally, the cord needs to be re-routed so it is not pinched by the handle.
