Makita 18V LXT® Lithium-Ion batteries charge faster and work longer than standard lithium-ion batteries, giving you and your Makita cordless tools unmatched performance and productivity for demanding applications. The Makita 3.0Ah battery (BL1830B) has a category-leading charge time of only 30 minutes, so it spends more time working and less time sitting on the charger.

The BL1830B is compatible only with Star Protection tools, indicated by the Star Symbol™ and/or Yellow Battery Receiver under the tool.
