Is the 8Ah worth it over the 6Ah DCB206?

If you run saws, grinders or other high-draw tools all day, yes: DeWalt claims up to one-third more runtime at the same size and weight. For light drilling, a smaller pack is cheaper and lighter.

Does it fit older DeWalt 20V MAX tools?

Yes. It works with any DeWalt 20V MAX tool and charger, including older models in that system. It does not fit the 12V MAX or FlexVolt-only slots.

Is a charger included?

No. The box has one DCB208 battery in clamshell packaging; chargers are sold separately. Charge time is about 60 minutes on a compatible fast charger.

How long does it run?

Runtime depends on the tool and load. At 160 watt-hours it roughly doubles a 4Ah pack and adds about a third over the 6Ah DCB206.
