2Pack 9.0Ah Replacement for Dewalt 20V 60V Flexvolt Battery Lithium Compatible with Dewalt 60 Volt Max Battery DCB609 DCB606 DCB612 DCB200 DCB201 DCB203 DCB204 DCB206 DCB207 DCB209 Power Tools

What It Is

This is a 2-pack of 9.0Ah aftermarket lithium-ion batteries designed to replace Dewalt’s 20V and 60V Flexvolt batteries. They power Dewalt 20V MAX tools (drills, saws, impacts) and 60V MAX outdoor equipment (mowers, trimmers, blowers) that accept the Flexvolt battery platform.

Fitment & Compatibility

• Voltage compatibility: Works with Dewalt 20V MAX tools and 60V MAX (Flexvolt) tools. Not compatible with older 18V NiCad or 20V XR slide-pack-only tools.
• Model cross-reference: Replaces OEM numbers DCB609, DCB606, DCB612, DCB200, DCB201, DCB203, DCB204, DCB206, DCB207, DCB209.
• Physical fit: Same dimensions as Dewalt Flexvolt batteries—fits all Dewalt tools that accept the slide-on Flexvolt battery pack (standard 20V tools and 60V mowers/trimmers).
• Before buying: Check your tool’s battery slot—if it has the tall, angled Flexvolt shape, these fit. For older 20V-only tools with a flat-bottom slot, use a Dewalt adapter (sold separately). Measure your existing battery’s length (approx. 5.5″) and height (approx. 4.5″) to confirm clearance in your mower’s battery compartment.

Key Things to Know

• Aftermarket vs. OEM: These are not genuine Dewalt. Performance (runtime, charge cycles) is generally good for the price, but peak power may be slightly lower under heavy load (e.g., a mower on thick grass).
• No battery gauge: Unlike genuine Dewalt Flexvolt batteries, these lack an LED fuel gauge—you won’t see remaining charge until the tool slows.
• Charger compatibility: Works with Dewalt 20V/60V chargers (DCB104, DCB107, DCB115, etc.). Do not use with older 18V or 12V chargers.
• Weight: 9.0Ah capacity means they’re heavy (~2.5 lbs each). Fine for mowers, but can make handheld tools feel unbalanced.

Should You Buy It

If you own multiple Dewalt 20V or 60V tools and need affordable backup batteries for light-to-medium use (trimming, drilling, occasional mowing), this 2-pack offers good value. Skip it if you need maximum runtime for heavy mowing or commercial use—genuine Dewalt Flexvolt batteries deliver more consistent power and a fuel gauge.
