What Battery Does the DeWalt DCH273 Use?
The DeWalt DCH273 runs on the DeWalt 20V MAX battery platform. Any DeWalt 20V MAX or XR battery will work, and FLEXVOLT batteries are backward-compatible.
About the DeWalt DCH273
The DeWalt DCH273 is a 20V MAX XR brushless SDS+ rotary hammer delivering 2.1J of impact energy. It features three modes (hammer drill, rotation only, hammer only), a 26mm maximum drilling capacity in concrete, and an active vibration control system to reduce operator fatigue. The brushless motor maximises runtime from each battery charge.

Recommended Battery
DCB205 or DCB206 — SDS hammers draw heavy current during percussion drilling. A 5.0Ah or 6.0Ah battery is the recommended minimum for concrete work.
Minimum Battery
DCB204 — A 4.0Ah battery handles lighter drilling in concrete, but battery life drops significantly during sustained heavy-duty work.
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.

Battery sizing, runtime & troubleshooting
Recommended pack: High-draw — a 5.0Ah is recommended; a compact 2.0Ah underperforms in concrete.
Compatibility caveats: Brushless motor. 2.1J impact energy, up to ~24mm in concrete.
If it won’t start or cuts out: Cut-out while drilling concrete means the pack is too small — fit a 5.0Ah.
Runtime: No official per-charge figure published.
Versus the adjacent model: Like the grinder and circular saw it is a high-draw tool — keep it on 5.0Ah packs, not compacts.
