Our take on the Battery Lithium-Ion 4.0AH / 20V MAX Dewalt

The DeWalt DCB204 is a 20V MAX XR lithium-ion battery pack rated at 4.0Ah. It fits DeWalt's 20V MAX cordless tools and chargers, and its 3-LED fuel gauge shows charge level at a glance. DeWalt rates the XR pack at up to 33% more capacity than its standard 20V MAX packs, and it weighs 1.42 lbs. It suits owners of DeWalt 20V tools who want longer runtime per charge and a spare to swap in, and it competes with DeWalt's own 2.0Ah and 5.0Ah packs and with third-party replacements.

Questions and answers

Which tools does the DCB204 fit?
It fits DeWalt 20V MAX cordless tools and chargers. It does not fit 12V MAX or FlexVolt-only tools.
How does it compare with the 2.0Ah pack?
It has twice the rated capacity, so tools run longer per charge, but it is larger and heavier than the compact 2.0Ah pack.
Does it have a charge indicator?
Yes. A 3-LED fuel gauge shows the state of charge when you press it.
Will it work with an older DeWalt 20V charger?
It works with DeWalt 20V MAX chargers. Very old chargers may charge it more slowly than newer models.
Is it worth it over the 5.0Ah pack?
The 4.0Ah pack is lighter and smaller than the 5.0Ah, so it suits tools where weight matters. The 5.0Ah gives longer runtime in high-draw tools.
Where is the Battery Lithium-Ion 4.0AH / 20V MAX Dewalt cheapest?
At RB Tools & Equipment, for $79.95, as of our latest check.
