Is the FLEXVOLT battery worth it if I only own 20V tools?

Mostly no. In 20V tools it behaves like a heavy 6.0Ah pack, and a DCB205 5.0Ah costs less. Buy it if you plan to add 60V tools.

Will it work in my existing DeWalt 20V tools and charger?

Yes. It fits 20V MAX tools and charges on existing 20V MAX chargers, about an hour for a full charge.

How is it different from the DCB205?

The DCB205 is 20V-only at 5.0Ah. This pack is 6.0Ah and switches to 60V in FLEXVOLT tools, so it adds voltage and runtime at more weight and cost.

Does it come with a charger?

No. The box has the battery only; chargers are sold separately.

How long does it run?

Runtime depends on the tool. Expect noticeably longer run time than a 5.0Ah pack in high-draw tools like circular saws and grinders.

Two-packs and kits with a charger usually cost less per amp-hour than the bare pack. Watch for bundle pricing around major sales.

Our take on the DeWalt 20V/60V MAX FLEXVOLT Battery DCB

The DeWalt DCB606 FLEXVOLT is a 6.0Ah lithium-ion pack that runs as a 20V MAX battery in 20V tools and switches to 60V MAX in FLEXVOLT tools. It weighs 2.25 lbs and has an LED state-of-charge gauge. It charges in about an hour on existing 20V MAX chargers. It is the pack to buy if you own or plan to own 60V DeWalt tools; 20V-only users pay a premium for voltage they cannot use.
