What Battery Does the Makita DGA452 Use?
The Makita DGA452 runs on the Makita 18V LXT battery platform. Any Makita 18V LXT battery will physically fit this grinder, though high-capacity batteries are essential for any meaningful grinding work.

Recommended Battery
BL1860B — Angle grinders are extremely power-hungry. The 6.0Ah battery is essential for any meaningful grinding or cutting work. Smaller batteries will drain in minutes under load.
Minimum Battery
BL1850B — A 5.0Ah battery works for intermittent grinding, but expect noticeably shorter runtime compared to the 6.0Ah during continuous use.
Battery Compatibility Notes
All Makita 18V LXT batteries use the same slide-on mount and will physically fit the DGA452. 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. However, for high-draw tools like angle grinders, lower-capacity batteries may struggle to maintain consistent voltage under heavy load, which can reduce cutting performance.

Battery sizing, runtime & troubleshooting
Recommended pack: Sustained grinding draws hard — a 5.0Ah is recommended; compact packs sag.
Compatibility caveats: 11,000 rpm, M14 spindle. Note: the 22.23mm figure on grinder pages is the disc BORE/arbor diameter, not disc thickness.
If it won’t start or cuts out: Speed loss or cut-out under load means the pack is too small or has overheated — fit a 5.0Ah and let a hot pack cool.
Runtime: No per-charge figure published.
Versus the adjacent model: One of the higher-draw LXT tools — give it your largest pack, not a compact.
