DCB609 20V 9.0Ah Replacement Battery (60V FLEXVOLT) for DeWalt 20V MAX 162Wh Cordless Tools

The HNF replacement battery for DeWalt 20V MAX 9.0Ah delivers heavy-duty runtime in a high-capacity lithium-ion pack. Rated at 9.0Ah / 162Wh at 18V nominal (20V MAX class), it powers demanding cordless tools — circular saws, reciprocating saws, rotary hammers, grinders and outdoor equipment — for longer cuts, more holes, and more cycles per charge than 5.0Ah or 8.0Ah packs.

This drop-in replacement is fully compatible with the entire DeWalt 20V MAX cordless tool line. The black-and-yellow housing matches OEM fit and finish, the sliding rail mates with original DeWalt 20V tools and chargers, and the integrated 4-LED fuel gauge shows remaining charge at a glance.

Application Scenarios

The 9.0Ah / 162Wh capacity is designed for users who push 20V MAX tools to their limits:

• Carpentry & framing — full-day runtime on circular saws, reciprocating saws, and impact drivers.
• Masonry & concrete — sustained power for rotary hammers drilling anchor holes and rebar.
• Metalworking — long cuts and grinding sessions without mid-shift charging.
• Outdoor & landscaping — hedge trimmers, chainsaws, leaf blowers running through a full property.
• Plumbing & electrical — long drilling cycles in ceilings and walls.
• Automotive — impact wrenches and grinders for shop and field repair.

Battery Maintenance Tips

• Charge the battery fully before first use.
• Avoid draining the pack below ~5% — recharging at 10-20% extends cycle life significantly.
• Store at 30-50% state of charge in a cool, dry place (10-25°C) if not used for over a month.
• Clean the contact rails periodically with a dry cloth to maintain a good electrical connection.
• Use only compatible 20V MAX chargers — third-party chargers without proper CC-CV profile can damage cells.
• Remove the battery from the tool during transport to prevent accidental activation.
