Here is your comprehensive buying guide for the best DeWalt lawn mowers and the essential batteries and tools that power them.

A Note Before We Start: DeWalt does not currently manufacture a stand-alone “lawn mower” as a complete unit. Instead, they sell the batteries, chargers, and bare tools (like blowers) that are essential for their cordless lawn mower ecosystem. The products listed here are the critical components you need to run a DeWalt mower (or any DeWalt OPE). The “mowers” themselves are sold as bare tools. This guide will help you choose the right batteries and supporting gear to get the best performance out of your DeWalt mower.

Our Top Picks at a Glance

  1. DEWALT 20V MAX 5 Ah 2-Pack (DCB205-2): The gold standard for most homeowners. Best for anyone who needs reliable, long runtime for a 20V mower or blower.
  2. DEWALT 20V MAX 5.0Ah (DCB205): The essential spare. Best for topping off your battery collection or replacing a worn-out single unit.
  3. DEWALT 20V MAX 5Ah Charging Kit (DCB205-2CK): The complete starter bundle. Best for new DeWalt owners who need batteries, a charger, and a storage bag in one box.
  4. DEWALT FLEXVOLT 6.0Ah (DCB606): The power upgrade. Best for those with a 60V MAX mower who want heavy-duty runtime and the ability to use it in 20V tools.
  5. DEWALT 20V MAX Blower (DCE100B): The essential cleanup tool. Best for clearing clippings off the driveway, deck, and sidewalk after you mow.
  6. DEWALT DCB609 (FLEXVOLT 9.0Ah): The marathon runner. Best for large lawns (over 1/2 acre) with a 60V MAX mower where runtime is the only priority.

How We Chose These Mowers

We evaluated these products based on the specific demands of cordless lawn care, not just workshop use.

  1. Runtime & Power Delivery: A lawn mower is a high-draw device. A battery that works fine for a drill might die in 10 minutes on a mower. We prioritized batteries with high amp-hour (Ah) ratings and the ability to sustain high current without overheating.
  2. Compatibility & Voltage: DeWalt’s ecosystem is split. 20V MAX batteries run the smaller mowers and blowers. FLEXVOLT batteries run the larger, more powerful 60V MAX mowers. We prioritized batteries that unlock the best performance for their respective platforms.
  3. Build Quality & Durability: Lawn care is dirty, hot, and vibration-heavy. We looked for batteries with robust casing, reliable cell quality (Li-ion), and a track record of surviving drops and temperature swings.
  4. Value & Ecosystem: A single battery isn’t enough. We considered the cost-per-Ah, the inclusion of chargers, and how well a battery integrates into a broader system (e.g., a 2-pack for a mower + a blower).

Detailed Reviews

DEWALT 20V MAX 5 Ah Lithium Ion Battery 2-Pack (DCB205-2)

Best for: The average homeowner with a 20V MAX mower and a few other yard tools. Price: $149.00 Rating: 4.7/5 (22,669 reviews)

This is the single most recommended battery setup for a reason. The 5.0Ah capacity is the sweet spot for 20V MAX mowers—it provides enough juice for a standard 1/4-acre lawn without being as heavy or expensive as the larger FLEXVOLT packs. The two-pack is critical because you can run one battery while the other charges, eliminating downtime. The only real weakness is that these batteries are not compatible with the high-power 60V MAX mowers. Verdict: The no-brainer starting point. Buy this if you own or are buying a 20V MAX mower.

DEWALT 20V MAX Battery, Lithium Ion, 5.0Ah (DCB205)

Best for: Owners who already have a charger and need a spare or replacement battery. Price: $77.99 Rating: 4.7/5 (20,600 reviews)

If you already own the 2-pack, this is your go-to for expanding your fleet. It’s the same reliable 5.0Ah cell as the pack above. It’s also a great option if you only have a small yard (under 1/8 acre) and a single charger, making a 2-pack overkill. The weakness is simple: buying singles is more expensive per battery than buying the 2-pack. Verdict: A solid, proven performer, but only buy this if you don’t need the charger or the second battery from the 2-pack.

DEWALT 20V MAX Battery Charging Kit (DCB205-2CK)

Best for: First-time DeWalt buyers or those starting their cordless OPE collection from scratch. Price: $179.00 Rating: 4.8/5 (13,887 reviews)

This is the “everything you need” box. It includes the same two 5.0Ah batteries from the DCB205-2, plus a standard charger and a surprisingly useful small storage bag. The bag is great for keeping the batteries and charger clean and organized in the garage or shed. The price is a slight premium over buying the batteries alone, but the included charger and bag make it a convenient, all-in-one solution. Verdict: The best value for a new user. Don’t buy the batteries separately unless you already have a charger.

DEWALT FLEXVOLT 20V/60V MAX Lithium Ion Battery, 6.0-Ah (DCB606)

Best for: Owners of a 60V MAX mower who want a balance of power and weight. Price: $134.99 Rating: 4.7/5 (9,454 reviews)

This is where you step into the big leagues. The FLEXVOLT battery automatically shifts voltage: it delivers 60V in a 60V mower (giving you serious cutting torque) and 20V in a 20V tool (giving you extended runtime). The 6.0Ah capacity in 60V mode is enough for a 1/3-acre lawn with a self-propelled mower. The weakness is that it’s heavier than a standard 20V battery, and it won’t fit in some older 20V tool cavities. Verdict: The ideal upgrade for a 60V MAX mower. It offers the best power-to-weight ratio in the FLEXVOLT line.

DEWALT 20V MAX Blower, 100 CFM (DCE100B)

Best for: Anyone who wants a quick, lightweight cleanup after mowing. Price: $114.48 Rating: 4.4/5 (15,418 reviews)

This is a bare tool (no battery included). It’s small, light, and perfect for blowing grass clippings off a driveway, patio, or sidewalk. It’s not a leaf vacuum or a heavy-duty leaf blower for wet leaves. The 100 CFM is modest, but the variable speed trigger gives you great control. The weakness is obvious: it’s underpowered for large leaf piles. Verdict: A perfect companion to any mower. Pair it with a 5.0Ah battery from the 2-pack above for a complete lawn care system.

DEWALT DCB609 (FLEXVOLT 9.0Ah)

Best for: Large properties (1/2 acre+) with a 60V MAX mower who absolutely need maximum runtime. Price: $148.45 Rating: 4.7/5 (7,747 reviews)

This is the heavyweight champion. The 9.0Ah capacity in 60V mode provides the longest runtime of any DeWalt battery. It will easily mow a half-acre on a single charge with a 60V mower. It also works in 20V tools, giving you a massive 9.0Ah runtime for a blower or trimmer. The weakness is its weight and size. It’s heavy, and it makes a mower feel front-heavy. It’s also expensive per battery. Verdict: Buy this only if you have a very large lawn and a 60V MAX mower. For most people, two 6.0Ah batteries are a better, more balanced setup.

What to Look for When Buying

  1. Voltage Match: 20V vs. 60V MAX: This is the most critical decision. A 20V MAX mower is lighter, cheaper, and fine for small, flat lawns (under 1/4 acre). A 60V MAX mower is heavier, more powerful, and necessary for thick grass, hills, and larger yards. A 60V battery will work in a 20V tool, but not the other way around. Match your battery to your mower’s voltage.
  2. Amp-Hours (Ah) ≠ Power: Ah is a measure of fuel tank size, not power. A 9.0Ah battery runs longer than a 5.0Ah, but it doesn’t spin the blade faster. For a mower, power comes from voltage (20V vs 60V) and the motor design. Don’t buy the biggest Ah battery if you don’t need the runtime—you’re just carrying extra weight.
  3. The 2-Pack Rule: Never buy a single battery for a mower. You need at least two. One runs the mower while the other charges. For a 20V mower, a 2-pack of 5.0Ah is the minimum. For a 60V mower, two 6.0Ah or two 9.0Ah batteries are ideal.
  4. Bare Tool vs. Kit: Most DeWalt m
