- •Some users report issues with charging the included 10AH batteries or shortening battery lifespan rapidly.
- •Not self-propelled, so it may require more effort on uneven or larger lawns compared to some electric mower competitors.

Bottom Line
If you’re after a quieter, eco-friendly mower that’s easy to start and store, the DeWalt 21.5 in. 20-Volt Max Lithium-Ion cordless push mower delivers solid initial performance and user-friendly features. However, it’s best for smaller lawns and lighter workloads due to declining battery life and less-than-ideal durability under heavy use. If you need longer runtime or a tougher mower for frequent, demanding mowing, you might want to explore other battery-powered models known for better battery endurance or self-propulsion for easier handling.
