Makita BL18120 12.0Ah 18V LXT Lithium-Ion Battery Maximum Runtime. Built for Tough Jobs.
Take your Makita 18V tools to the next level with the BL18120 12.0Ah high-capacity battery — engineered for professionals who need longer working time between charges. By increasing the number of cells compared to the BL1860 (6.0Ah), this powerhouse delivers extended runtime across all cordless tools in the 18V LXT system.
Built to Withstand the Jobsite
Featuring a shock-absorbing structure inspired by Makita’s 40V Max XGT range, the BL18120 offers enhanced impact resistance, reducing the risk of damage from accidental drops and rough handling.

What are the benefits of the new "Star" Battery
The demanding applications you take on every day are also demanding on your cordless tools and batteries. You rely on your tools, so Makita created STAR Protection Computer Controls™. STAR Protection is communication technology that allows the tool and battery to monitor conditions and exchange data in real time to protect against Overloading, Over-Discharging and Over-heating. Look for Makita tools and batteries with the STAR and get these protection features.
OVERLOAD PROTECTION
High-drain applications require maximum battery power. Makita tools and batteries are engineered for industrial applications, but sustained peak demand can overload the tool. Makita’s STAR Protection Computer Controls™ allow the battery and tool to communicate and protect your tool and battery from overload by cutting power when put under abnormally high current draw.
OVER-DISCHARGE PROTECTION
Lithium-ion batteries are engineered for longer, sustained performance. But running a battery until it’s “dead” empty can damage the cells. Makita STAR Protection Computer Controls™ monitor battery charge capacity, and if the battery is too low to complete the application it will cut power in order to extend battery life.
OVER HEAT PROTECTION
Extreme heat is the enemy of ALL batteries. It can make batteries charge slower, damage battery cells, and reduce battery life. Makita STAR Protection Computer Controls™ monitor battery heat during operation. If the battery reaches a certain level of heat it will cut power to the tool.
