                Answer This Question

                Batteries doesn't need to be the same capacity. You can use any whether 20V MAX or FLEXVOLT® 20/60V MAX battery no matter the amp/hr value.

                  The lawn mover was bought together with to 12 ah batteries and expectation was to forgot about maintenance and enjoy of beauty of electric power tools but things are very interesting right after the warranty over. Purchased: May 2023 Product: Two DEWALT FLEXVOLT 12Ah batteries included with a lawn mower Usage: Residential only, light use Storage: Indoors, properly maintained Failure: Both batteries failed in nearly the same way Customer service response: Warranty denied because of expiration My expectation: Premium batteries should last significantly longer under light residential use. The mower came with two FLEXVOLT 12Ah batteries. I am a homeowner, not a contractor, so these batteries received only light residential use. They were always stored indoors, never dropped, never exposed to water, and were well maintained. After only about three years, both batteries failed in nearly the same way. They would no longer charge properly or hold a charge, making the mower unusable. I followed DEWALT's recommended troubleshooting steps, but they did not resolve the issue. I contacted DEWALT Customer Support, provided proof of purchase, photographs, and all requested information. My warranty claim was denied because the batteries were just outside the warranty period. Although I understand the written warranty policy, I was disappointed that no goodwill accommodation was offered, especially considering that both premium batteries failed after light residential use and my long history as a DEWALT customer. I believe premium 12Ah FLEXVOLT batteries should provide a significantly longer service life under normal homeowner use. My disappointment is not only with the battery failure, but also with the lack of flexibility in resolving what I believe is an unusual situation. I am sharing this experience so other customers can make informed purchasing decisions. I hope DEWALT reviews cases like this individually and considers supporting loyal customers when premium products fail unexpectedly after relatively limited use. If DEWALT reaches out and resolves this matter in a fair way, I will gladly update this review to reflect that experience.

                    Don’t waste your money
                    Worst purchase ever pay extra for the name the thing can’t even mow a half a tiny lawn before the batteries die.

                      I don’t recommend this!
                      I’ve had this for over a year now & it’s been nothing BUT a pain. The battery's don’t even hold a charge. I bought new battery’s which are soooo expensive thinking this would resolve the problem, nope I only get maybe 30 mins & it’s dead. I have to keep recharging. It takes over 8 hrs to change so you can imagine it takes 2 days just to mow my front yard. I want to spare everyone the headache. Don’t get this!!!

                        Nice but somewhat disappointed
                        I have about 1/3 acre yard to mow. All my corded and cordless tools are Dewalt, so I purchased this mower to be able to share batteries, approximately 2 months ago. I have no issues with the quality of the mower. The mower is easy to use and has plenty of power to mow my yard. It was easy to put together without the need for tools. However, I do have a few concerns. We must bag the grass. If we try to mulch, our dogs track the grass onto the house. The bag is too small. Additionally, the way it installs, it tilts upward. Due to this, the mower is not able to discharge the grass to the rear of the bag. It tends to clog the discharge chute so you have to stop and clear it by hand a couple of times bag full. It is a poor design. Finally, this mower does not cut the grass evenly. No matter what height I set it to, it leaves strips of longer grass. See picture. I will continue to attempt to make adjustments. If I figure out how to make it cut evenly, I will update this review.

                          Absolutely not.
                          Many issues! Uses legacy flexvolt 12 amp batteries; big mistake. The 2 batteries don’t have the energy to do basic 1/4 acre yard. Don’t even have a common docking station. The 2 legacy individual chargers require two outlets! Another issue; these batteries become less and less capable over time. Now it takes four full charges just to mow my 1/4 acre property. The last issue is the plastic throttle squeeze handle made of low grade plastic. It will eventually break, as it did for me!

                            Wide open you have to walk fast.👍
                            I like it! I have a small yard 120' x120' and am able to mow it twice on one charge. I let the batteries charge overnight before I mow as that is about how long it takes. I did not use the grass catcher yet. This mower was assembled in Mexico. Two things came to my attention: the upper case where the batteries go seems to have separated a little and the left wheel does not align as the right.does. It does not appear to affect the operation of it. I do not like the plastic trigger to engage the drive. It is wonderful not to have to worry about gas, oil, and oil changes. At 70 it is great not to have pull a cord to start it.

                              Poor Quality
                              This is the first Dewalt product I've had a problem with. The first mower was missing the mulch plug, the self drive did not work, and had an issue with the charger. The second mower customer service sent, the handle was cracked, missing batteries, missing mulch plug, and the self drive didn't work. The THIRD mower that was sent, WORKED. So far no issues with the THIRD mower. THIRD time is a charm!

                                  Order two. One did not come with a bag...
                                  Order two. One did not come with a bag frame while the other came with a bag frame for another mower. Bag and frame failed to seal to mower on top and bottom of the chute. For an $800 mower, someone needs to be doing QC in the Dewalt Factory (Mexico). Called Dewalt and they could not be of assistance within the first 90 days following purchase. All fine but there was no way for HD to fix this one. Loyal Dewalt purchaser and tried to stay in the Dewalt battery family but not this time. Ended up going Milwaukee and design and material construction is superb to what Dewalt gave for their top of the line cordless mower.
