What It Is

This is a high-capacity 6500mAh lithium-ion replacement battery for Dewalt 40V MAX power tools and outdoor equipment. It’s designed to replace original Dewalt batteries (DCB404, DCB406, DCB407, DCB114, DCB116) and works with all Dewalt 40V MAX tools and chargers—ideal for mowers, trimmers, blowers, and chainsaws needing longer runtime.

Fitment & Compatibility

• Tool Compatibility: Fits all Dewalt 40V MAX tools and chargers (e.g., DCCS690B chainsaw, DCST970 trimmer, DCBL720 blower). Not compatible with Dewalt 20V or FlexVolt systems.
• Charger Check: Works with Dewalt 40V chargers (e.g., DCB115, DCB1106). Do not use with 20V or 60V chargers.
• Physical Fit: Same footprint as OEM DCB404/DCB406/DCB407—slides into tool battery ports without modification. Measure height if using under-deck mower models (e.g., DCMW220) to ensure clearance.
• OEM vs Aftermarket: This is a third-party replacement. It may not have the same over-discharge or temperature protection as genuine Dewalt. Check that your tool’s battery contacts are clean and undamaged.

Key Things to Know

• Capacity vs OEM: 6500mAh is ~30% larger than stock DCB404 (5Ah). Expect longer runtime but slightly heavier weight (~1.5 lbs).
• Quality Risk: Only 4 reviews at 3.6 stars—some users report reduced lifespan or compatibility hiccups with older chargers. Test with your specific charger before heavy use.
• Installation: No tools needed—slide onto tool until it clicks. Ensure battery is fully charged on a Dewalt 40V charger for first use (may take 2-3 hours).
• Gotcha: May not fit in some tight battery compartments (e.g., older mower models with angled slots). Measure your original battery’s dimensions (approx. 5.5” x 3.5” x 2.5”) to confirm.

Should You Buy It

Buy this if you need extended runtime for a Dewalt 40V tool (especially a mower or chainsaw) on a budget, and you’re comfortable with a third-party battery’s potential reliability trade-offs. Skip it if you want guaranteed OEM protection circuits, or if your tool requires a snug battery fit—stick with genuine Dewalt for peace of mind.
