DeWalt 20V MAX Battery Compatibility

The DeWalt 20V MAX system is one of the most widely-used cordless platforms in the world. All 20V MAX batteries are compatible with all 20V MAX tools, and DeWalt’s FLEXVOLT batteries extend that compatibility further.

TL;DR

• All DeWalt 20V MAX batteries are compatible with all DeWalt 20V MAX tools.
• FLEXVOLT batteries are backward compatible and also work in 20V MAX tools.
• Standard 20V MAX batteries do NOT work in 60V or 120V FLEXVOLT-only tools.
• 20V MAX is not compatible with 12V MAX tools or batteries.
• Check your tool’s voltage nameplate before purchasing batteries.

Compatibility Rules

Within the DeWalt 20V MAX system, all batteries — from the compact 1.3Ah to the high-capacity 5.0Ah and beyond — are fully interchangeable across tools. The FLEXVOLT battery system is backward compatible: FLEXVOLT batteries automatically downshift to 20V when used in 20V MAX tools, providing extended runtime.

What It Is NOT Compatible With

Charger Notes

DeWalt 20V MAX chargers (DCB1xx series) are compatible with all 20V MAX and FLEXVOLT batteries. Multi-voltage chargers can charge both platforms. Always use a genuine DeWalt or DeWalt-approved charger to maintain battery health and warranty coverage.

Compatible Tools List

The DeWalt 20V MAX system is one of the industry’s largest cordless platforms with over 250 compatible tools. All 20V MAX tools use the same DEWALT 20V MAX batteries (DCB201, DCB203, DCB204, DCB205, DCB206 and XR variants). The system also includes ATOMIC (compact) and XR (brushless/high-performance) sub-lines — all sharing the same 20V MAX battery.
