The DeWalt 20V MAX system is DeWalt’s main 18V-nominal cordless platform (sold as 18V XR in the UK). 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.
- We found no DeWalt statement that 12V MAX packs fit 20V MAX tools, or the reverse — treat them as separate platforms.
- Check your tool’s voltage nameplate before purchasing batteries.
Compatibility Rules
Within the DeWalt 20V MAX system, all batteries — from compact packs to high-capacity packs — are fully interchangeable across tools. The FLEXVOLT battery system is backward compatible: DeWalt says a FLEXVOLT battery operates as an 18V (20V MAX) battery in an 18V product.
What It Is NOT Compatible With
| Platform | Compatible? | Notes |
|---|---|---|
| DeWalt 20V MAX tools | ✅ Yes | Full cross-compatibility within 20V MAX |
| DeWalt FLEXVOLT batteries in 20V MAX tools | ✅ Yes | FLEXVOLT auto-adjusts to 20V |
| DeWalt 60V/120V FLEXVOLT tools | ❌ No | DeWalt lists only FLEXVOLT packs for its 54V (60V MAX) tools |
| DeWalt 12V MAX | ❌ No | Separate platform; we found no DeWalt cross-fit statement |

Charger Notes
Battery lists differ by charger: the DCB118 manual says it is “designed to charge DeWALT 20V Max* lithium-ion and FLEXVOLT battery packs”, but the DCB115 manual we checked lists the DCB606 and no larger FLEXVOLT packs. Check the list in your charger’s manual, and use a genuine DeWalt charger.

Compatible Tools List
The DeWalt 20V MAX system has a large range of 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 — fits 20V MAX tools, and DeWalt says a FLEXVOLT pack operates as an 18V (20V MAX) battery in an 18V product. In the UK the same range is sold as 18V XR.
What is the difference between 20V MAX and 20V?
DeWalt’s “20V MAX” is the maximum initial battery voltage, measured without a workload; the nominal voltage is 18V, the same nominal figure Makita and Milwaukee use for their 18V packs. Nominal voltage alone does not tell you how two tools compare in power.
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. Large 6.0Ah and up: saws, grinders, outdoor tools. FLEXVOLT: needed only for 60V (UK: 54V) tools, though it also runs 20V MAX tools. POWERSTACK: DeWalt’s premium 20V MAX packs.
