Our take on the DEWALT DCB609 FLEXVOLT 20V/60V MAX Lithium-Ion 9.0Ah Battery

The DEWALT DCB609 is a FLEXVOLT lithium-ion pack that runs at 20V MAX in 20V DEWALT tools and at 60V MAX in FLEXVOLT tools. Its 9.0Ah capacity is one of the largest in the FLEXVOLT line, so it suits high-draw tools like circular saws and grinders that drain smaller packs quickly. The trade-off is weight and bulk: it is noticeably heavier than a 2.0Ah or 5.0Ah pack, which matters on tools you hold overhead. Owners generally rate the runtime and build, while criticizing the weight and the higher cost of FLEXVOLT packs.

Questions and answers

Does this battery work in regular DEWALT 20V tools?
Yes. It runs at 20V MAX in standard DEWALT 20V MAX tools and at 60V MAX in FLEXVOLT-rated tools.
How is it different from the 6.0Ah FLEXVOLT pack?
It has more capacity, so longer runtime, but it is heavier and larger than the 6.0Ah pack.
Will it fit my DEWALT charger?
It uses the DEWALT 20V MAX charger family, so most current DEWALT 20V chargers accept it.
Is 9.0Ah too much for small tools?
For drills and drivers it adds weight without much benefit. It pays off most in saws, grinders and other high-draw tools.
Does it have a charge indicator?
Yes, the pack has a built-in charge-level indicator.
Can I leave it on the charger?
DEWALT chargers are designed to maintain packs, but storing it partly charged and cool is easier on the cells.
