Recommended Battery

DCB205 or DCB206 — Angle grinders are among the most power-hungry 20V tools. A 5.0Ah or 6.0Ah battery is essential for any sustained grinding or cutting work.

Minimum Battery

DCB204 — A 4.0Ah battery works for intermittent grinding, but expect very short runtime during continuous use.

Battery Compatibility Notes

All DeWalt 20V MAX batteries share the same rail-mount system. FLEXVOLT batteries are backward-compatible at 20V. Higher Ah ratings mean longer runtime, not more power.
