DEWALT 20V MAX Battery Charging Kit, Includes Charger and 2 Batteries, 5Ah, Includes Small Storage Bag (DCB205-2CK)

What It Is

The DEWALT DCB205-2CK is a 20V MAX battery charging kit that includes two 5Ah lithium-ion batteries, a charger, and a small storage bag. It powers and recharges any DEWALT 20V MAX tool, including lawn mowers, string trimmers, blowers, and hedge trimmers, plus all 20V MAX workshop tools.

Fitment & Compatibility

• Brand & platform: Works exclusively with DEWALT 20V MAX tools and chargers. Not compatible with DEWALT 60V MAX FlexVolt or 40V MAX systems.
• Tool compatibility: Fits any DEWALT 20V MAX lawn mower (e.g., DCMW220, DCMW225), trimmer (e.g., DCST920, DCST970), blower (e.g., DCBL720, DCBL722), and hedge trimmer (e.g., DCHT820). Also powers all 20V MAX drills, saws, and lights.
• Battery size: 5Ah capacity is larger than standard 2Ah or 3Ah packs; ensure your tool’s battery compartment can accommodate the slightly taller and heavier form factor. Most DEWALT 20V MAX tools accept it, but check for clearance on compact models.
• Charger: Includes a standard 20V MAX charger (model DCB115 or similar). Charge time for a fully depleted 5Ah battery is approximately 90–120 minutes.
• Storage bag: Soft-sided zippered bag holds two batteries and the charger. Not weatherproof or impact-rated.

Key Things to Know

• Quality: Genuine DEWALT cells with reliable battery management system (BMS) prevent overheat, over-discharge, and short circuits. 5Ah provides longer run time than 2Ah or 3Ah packs—good for mowing a ¼-acre lawn on one charge.
• Installation difficulty: None. Slide battery onto tool until it clicks. Charger plugs into standard 120V outlet. No wiring or modification needed.
• Common gotchas: Batteries are heavy (about 1.5 lbs each). If your mower uses two batteries (e.g., DCMW225), this kit gives you one pair. The bag is small—won’t fit larger 6Ah or 9Ah packs. Always store batteries at room temperature; cold reduces run time.
• Compatibility note: Does not include a tool. If you need a mower or trimmer, buy separately.

Should You Buy It

Buy this kit if you already own a DEWALT 20V MAX lawn tool (or plan to buy one) and need reliable, high-capacity batteries with a charger and organized storage. It’s ideal for homeowners with medium-sized yards who want extended run time without buying multiple smaller packs. Skip it if you need 60V FlexVolt power or already have enough 5Ah batteries.
