What Battery Does the Makita DHR243 Use?
The Makita DHR243 runs on the Makita 18V LXT battery platform. Any Makita 18V LXT battery will physically fit this rotary hammer, though the high power demands of percussion drilling mean larger batteries are strongly recommended.
About the Makita DHR243
The Makita DHR243 is a powerful 18V LXT brushless SDS+ rotary hammer with 2.0J of impact energy. It features three modes (rotary hammer, hammer only, rotary only), a 24mm drilling capacity in concrete, and Anti-Vibration Technology (AVT) for reduced operator fatigue during extended use.
Compatible Batteries for the Makita DHR243
All Makita 18V LXT batteries are compatible with the DHR243. Here is how each option compares:
| Battery Model | Capacity | Weight | Rating |
|---|---|---|---|
| BL1815 | 1.5Ah | 0.35kg | Not Recommended |
| BL1820 | 2.0Ah | 0.37kg | Not Recommended |
| BL1830 | 3.0Ah | 0.46kg | Compatible |
| BL1840 | 4.0Ah | 0.56kg | Compatible |
| BL1850B | 5.0Ah | 0.64kg | Compatible |
| BL1860B | 6.0Ah | 0.67kg | Recommended |
Recommended Battery
BL1860B — SDS hammers draw heavy current during percussion drilling. The 6.0Ah battery is the recommended minimum for concrete work to avoid mid-hole battery drops.
Minimum Battery
BL1850B — Will power the hammer for lighter drilling in concrete, but battery life will be significantly reduced during heavy-duty work.
Battery Compatibility Notes
All Makita 18V LXT batteries use the same slide-on mount and will physically fit the DHR243. Star Protection batteries communicate with the tool to prevent overheating, over-discharging, and over-current for optimal performance.
Higher Ah ratings mean longer runtime, not more power. For rotary hammers working in concrete, battery capacity directly affects how many holes you can drill per charge.
