Which batteries does the DCB1404 charge?

It charges DeWalt 20V MAX lithium-ion packs. It does not charge 12V, 60V FlexVolt or older 18V NiCad batteries.

How is it different from DeWalt's fast chargers?

It is a basic single-bay charger with a slower charge rate. DeWalt's fast chargers fill packs quicker and some handle several batteries at once.

DeWalt's charger circuitry manages the charge, but for long storage it is better to take the pack off once it is full.

No. This is the charger only, so you need a DeWalt 20V battery to use it.

Yes if you want a spare charging point in another room, bag or vehicle. If you need speed or several bays, a higher-tier DeWalt charger fits better.
