2-Packs 8000mAh Replace for Dewalt 20V Max Battery Compatible with DCB206 DCB201 DCB203 DCB207 DCB205 DCB204 Compatible with Dewalt 20V Cordless Power Tools and Chargers

What It Is

This is a 2-pack of 8000mAh aftermarket lithium-ion batteries designed to replace the Dewalt 20V Max DCB200-series batteries (DCB201, DCB203, DCB204, DCB205, DCB206, DCB207). They power any Dewalt 20V Max cordless lawn mower, trimmer, blower, or other outdoor power tool that uses a slide-on battery.

Fitment & Compatibility

• Check your tool’s voltage: Only for Dewalt 20V Max tools (not 20V/60V FlexVolt or 18V NiCad).
• Battery shape & slide: These fit all Dewalt 20V Max slide-on battery ports (same footprint as OEM DCB205). No adapter needed.
• Charger compatibility: Works with all Dewalt 20V Max chargers (DCB101, DCB102, DCB104, DCB107, DCB110, etc.). Do not use on 60V or 12V chargers.
• Physical size: Slightly taller than OEM DCB205 (about 1/2 inch). Measure your tool’s battery compartment depth to ensure clearance (especially on mowers with enclosed bays).
• Capacity: 8000mAh (vs. 5.0Ah OEM DCB205). Higher runtime for mowers and trimmers, but may be heavier.

Key Things to Know

• Not OEM: This is an aftermarket battery. It lacks Dewalt’s over-discharge protection circuit—stop using when tool slows to avoid cell damage.
• Weight: Each battery weighs ~1.5 lbs (20% heavier than a 5.0Ah OEM). Can unbalance handheld tools like trimmers.
• Installation: No tools needed. Slide onto tool until it clicks. If it doesn’t seat flush, check for debris in the slide rails.
• Warranty: Typically 1-year vs. Dewalt’s 3-year on OEM. No repair/replacement service—just return to seller.

Should You Buy It

Buy this if you need high-capacity backup batteries for multiple Dewalt 20V tools (especially a mower or blower) and are comfortable with aftermarket reliability for a lower price. Skip it if you want OEM safety circuits, a lighter battery for handheld tools, or a longer warranty.
