The Makita 18V Compact Lithium-Ion battery charges faster and works longer than standard compact lithium-ion batteries, giving you and your cordless tools unmatched performance and productivity to take on the most demanding applications. The Makita 2.0 Ah battery combines more run time (50% more run time per charge than the Makita BL1815 battery) with a category-leading charge time of only 25 minutes, so it spends more time working and less time sitting on the charger.
