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.

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.

Are all DeWalt 20V MAX batteries interchangeable?
Yes. Every battery labelled 20V MAX — including standard, XR, POWERSTACK, and FLEXVOLT — works in every 20V MAX tool. FLEXVOLT batteries switch to 20V mode automatically when inserted into a 20V tool. This universal compatibility is a core design principle of the platform.
What is the difference between 20V MAX and 20V?
DeWalt’s “20V MAX” refers to the peak (unloaded) voltage of a fully charged battery. The nominal (working) voltage is 18V, which is standard across the industry. Other brands like Milwaukee and Makita label their equivalent batteries as 18V. The actual performance is comparable — the labelling is a marketing convention.
How do I choose between DeWalt 20V MAX battery sizes?
Match battery size to tool demand. Compact 1.5-2.0Ah: impact drivers, drills, lights. Mid-range 4.0-5.0Ah: most tools, best all-around. Large 6.0Ah+: saws, grinders, outdoor tools. FLEXVOLT: only if you own 60V tools. POWERSTACK: premium option for best power-to-weight ratio.
