DEWALT 20V MAX* XR Battery, 8.0-Ah (DCB208)

What It Is

The DEWALT DCB208 is an 8.0-Ah, 20V MAX* XR lithium-ion battery designed for high-drain DEWALT lawn mowers, trimmers, blowers, and other 20V outdoor power equipment. It delivers extended runtime for larger yards or heavy-duty tasks.

Fitment & Compatibility

• Voltage & Platform: Only works with DEWALT’s 20V MAX* tools and chargers (not 12V or 60V FlexVolt).
• Physical Fit: The DCB208 is a “slide-pack” battery—fits all DEWALT 20V slide-mount tools and mowers (e.g., DCMW220, DCMW225, DCMW240).
• Mower Check: Ensure your mower’s battery compartment accommodates the slightly larger 8.0-Ah pack (it’s taller than 5.0-Ah or 2.0-Ah packs). Measure compartment height—some older mower models may have clearance issues.
• OEM vs. Aftermarket: This is genuine DEWALT; aftermarket “compatible” batteries often lack the same cell quality, thermal management, or charging circuitry.
• Charger Compatibility: Works with all DEWALT 20V chargers (DCB107, DCB112, DCB115, etc.), but charges fastest on a DCB115 (4A) or higher.

Key Things to Know

• Runtime vs. Weight: 8.0-Ah gives roughly 60% more runtime than a 5.0-Ah pack, but weighs about 1.5 lbs—noticeably heavier on handheld tools.
• Installation: No tools needed—slide onto tool until it clicks. Ensure the locking latch engages fully to avoid drops.
• Common Gotcha: The DCB208 uses lithium-ion cells; never store fully drained or in extreme heat (above 140°F). Partial discharge cycles extend lifespan.
• Fuel Gauge: Built-in 3-LED indicator shows approximate charge level—press the button to check before starting a job.

Should You Buy It

Buy this if you have a DEWALT 20V mower or high-drain tool and need maximum runtime for large lawns or extended trimming sessions. It’s overkill for occasional light use—a 5.0-Ah pack will save weight and cost. If you already own a 20V DEWALT system, this is a reliable OEM upgrade.
