8.0Ah Battery Replacement for Dewalt 20V MAX Battery,with DCB112 Charger,Compatible with DCB200 DCB201 DCB203 DCB206

What It Is

This is a high-capacity 8.0Ah aftermarket battery replacement for DEWALT 20V MAX cordless lawn mowers, trimmers, blowers, and other outdoor power equipment. It includes a DCB112 charger and is designed to extend runtime for heavy-duty yard work.

Fitment & Compatibility

Before buying, confirm your tool uses a DEWALT 20V MAX slide-pack battery (not the older 18V or flexvolt system). This battery is compatible with DEWALT models DCB200, DCB201, DCB203, and DCB206. It works with all DEWALT 20V MAX tools, including lawn mowers like the DCMW220, DCMW225, and DCMW230. The DCB112 charger is a standard 1.25A unit—check that your tool’s original charger is the same voltage (20V) and that the battery slides on without forcing. Measure the battery compartment: this 8.0Ah pack is slightly taller than a 5.0Ah, so ensure your mower’s battery bay has enough clearance (approx. 5.5 x 3.5 x 2.5 inches).

Key Things to Know

• Quality: Aftermarket battery, not genuine DEWALT. May have slightly lower cycle life and no OEM warranty. The DCB112 charger is a basic slow charger—fine for overnight, but not fast.
• Installation: Slide battery onto tool until it clicks. No tools needed. If it doesn’t lock in, check for debris on contacts.
• Gotcha: The 8.0Ah capacity is higher than standard (e.g., 5.0Ah), so runtime is longer, but weight is heavier (~2.5 lbs). May cause balance issues on lighter trimmers.
• Common issue: Some users report the battery indicator lights not matching genuine DEWALT units. Test immediately—if it doesn’t charge or hold power, return promptly.

Should You Buy It

This is a budget-friendly option for homeowners who need extended runtime for mowing large lawns or heavy trimming, and who don’t mind a heavier battery and slightly lower build quality compared to OEM. Best for occasional use, not daily professional work.
