At 6.0Ah versus 5.0Ah, this battery stores 20% more energy, which translates to roughly 20% longer runtime under the same workload — meaning fewer battery swaps on high-drain tools like circular saws and grinders.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003ch4\u003eIs this battery compatible with my Makita BL1830B?\u003c\/h4\u003e\n\u003cp\u003eYes.
