Unlimited Versatility: One Battery System for Your Entire Tool Trailer.

Revolutionize your jobsite productivity with the DEWALT DCB609-2. The FLEXVOLT® system is the world’s first battery that automatically changes voltage when you change tools. This 2-pack provides two 9.0Ah high-capacity batteries, delivering the raw power of corded tools to the 60V MAX* platform while offering 6X the runtime when used with your existing 20V MAX* tools.

Whether you're ripping through LVLs with a 60V circular saw or running a 20V impact driver all day, the DCB609-2 ensures you have the sustained current needed to finish the job without a trip to the charger.

Key Features & Professional Benefits:
