20 V 4000 mAh lithium-ion battery pack

This four-pack supplies 20 V lithium-ion cells rated at 4000 mAh each. They are built as direct replacements for Dewalt DCB2045 and a long list of 18 V and 20 V MAX battery codes. The yellow finish matches the Dewalt tool line.

Compatibility limited to Dewalt 20 V MAX platform

The batteries only work with Dewalt 20 V MAX cordless tools such as the DCD, DCF, DCG and DCS series drills, drivers, grinders and saws. They will not operate on other brands or on Dewalt 12 V or 60 V FlexVolt systems.

Replaces lower-capacity Dewalt packs

Users moving up from 1.5 Ah or 2.0 Ah original packs gain longer run-time per charge for the same tool weight. The jump is worthwhile when extended use between charges matters more than the added cost of higher-capacity cells.

Questions about this item

Should I choose the 4-pack or buy single batteries for my 20V tools?

The 4-pack gives you four 4000mAh cells in one carton, so you can keep spares charged and swap them without downtime on any 20V MAX tool.

What does the 4000mAh rating actually deliver on a 20V MAX drill or saw?

At 20V nominal the pack stores roughly 80Wh, which typically runs a DCD780 drill through several hundred holes or a DCS391 saw through dozens of cuts per charge.

Does the DCB2045 interface limit current on high-draw tools like the DCF895 impact driver?

The battery uses the standard 20V MAX slide-on connection, so it supplies the same peak current the tool requests; no firmware cap is imposed by the pack itself.
