DEWALT 20V MAX 5 Ah Lithium-Ion Battery and Charger Starter Kit (DCB205C)

What It Is

This is a genuine DEWALT 20V MAX 5 Ah lithium-ion battery (DCB205) paired with a standard charger (DCB115). It powers any DEWALT 20V MAX tool, including their walk-behind mowers (e.g., DCMW225, DCMW220), string trimmers, blowers, and hedge trimmers. Not for gas mowers or other brands.

Fitment & Compatibility

• Works with: All DEWALT 20V MAX tools (18V NiCad tools require an adapter, sold separately). Check your mower’s voltage requirement—this is 20V, not 60V or 120V.
• Deck size: Compatible with DEWALT 20V mowers up to 21-inch decks (e.g., DCMW225). For larger decks, you may need two batteries or higher amp-hour (Ah) packs.
• OEM only: This is a genuine DEWALT part. Aftermarket batteries may not fit or charge correctly with this charger. Avoid knockoffs.
• Measurements: Battery dimensions: 4.5 x 3.0 x 2.5 inches; charger: 7.5 x 5.5 x 4.0 inches. Ensure your storage or mower compartment fits both.

Key Things to Know

• Quality: Trusted OEM lithium-ion cells with overcharge/over-discharge protection. The 5 Ah capacity gives roughly 30–45 min runtime on a DEWALT 20V mower (medium grass), longer on lower-drain tools like trimmers.
• Installation: No tools needed—slides directly onto the tool. The charger has a 1-hour charge time for a depleted 5 Ah pack.
• Gotcha: This kit includes only one battery. For continuous mowing on a larger lawn (over ¼ acre), you’ll likely need a second battery to swap while the first charges. Also, the charger is not a rapid charger (DCB118) – it’s the standard 1-hour model.
• Storage: Store at room temperature, not in direct sun or freezing conditions. Lithium-ion degrades in extreme heat/cold.

Should You Buy It

Yes, if you already own DEWALT 20V tools and need a reliable battery + charger starter for light-to-medium mowing or yard work. It’s a solid value for the price, but consider buying a second battery if you have a large lawn or plan to use high-drain tools continuously. Avoid if you need 60V or 120V power for heavy-duty mowing.
