Bottom Line

While the Dewalt DCB609 FLEXVOLT Battery is compatible with 20V, 60V, and 120V tools, it faces significant criticism for its reliability and lifespan issues. If you're a devoted Dewalt tool user, be prepared for potential battery replacements, which can add up cost-wise. For those looking for longer-lasting batteries, it may be wise to explore other brands known for more durable power solutions. Ultimately, despite the praise for Dewalt tools, these batteries are considered a weak point in their lineup.
