12000mAh Replacement Battery for Dewalt 20V/60V Max Batteries 2 Pack Compatible with Dewalt 20V/60V Cordless Power Tools DCB606 DCB609 DCB612 DCB200 DCB206 DCB207

What It Is

This is a two-pack of 12000mAh aftermarket lithium-ion batteries designed to replace OEM Dewalt 20V/60V MAX batteries, intended for use in Dewalt cordless lawn mowers, trimmers, blowers, and other outdoor power tools.

Fitment & Compatibility

Before buying, confirm your tool uses a Dewalt 20V MAX or 60V MAX slide-in battery interface (the same shape as DCB606, DCB609, DCB612, DCB200, DCB206, DCB207). This pack will not fit Dewalt XR FlexVolt tools that require a different contact layout. Check your mower’s battery compartment dimensions: these are slightly larger than standard 5Ah packs, so measure the opening (approx. 6 x 3 x 2.5 inches per battery). They are aftermarket, not OEM Dewalt, so expect no battery gauge or communication with Dewalt chargers—use only the included charger.

Key Things to Know

• Charger compatibility: These batteries come with their own charger. Do not attempt to charge them on a genuine Dewalt charger—it may damage the charger or battery.
• Capacity vs. runtime: 12000mAh is roughly 2.5x the capacity of a standard 5Ah Dewalt battery. In a 20V mower, expect 45–60 minutes of continuous cutting on a medium lawn (actual runtime depends on grass thickness and mower draw).
• Build quality: Aftermarket cells (likely not Samsung/LG) may have shorter cycle life than OEM. The 3.5-star rating suggests some units fail early—buy from a seller with a return policy.
• Weight: Each battery weighs about 2.2 lbs, so a two-pack adds 4.4 lbs total—noticeable on a handheld trimmer but fine for a mower.

Should You Buy It

Buy this only if you need cheap, high-capacity backup power for multiple Dewalt 20V tools (especially a mower or blower) and you’re comfortable with aftermarket reliability risks. It’s a budget option for heavy users who don’t want to pay OEM prices, but expect shorter lifespan and no warranty support. If you demand consistent performance and safety, stick with genuine Dewalt batteries.
