2 x Makita BL1830 Li-Ion 3.0ah Battery + DC18SD 9.6-18v 30 Minute Fast Charger

2 x Makita BL1830 18v 3.0AH BatteryBL1830 Makita 18v 3Ah LXT Lithium-Ion battery and optimum charging system produces 280% more lifetime work with 2x more cycles 

5x Lower self-discharge keeps battery cells active and ready for use, even after long periods of storage 
Charging at any time will have no effect on the battery, built-in shock absorbing features protect the battery 
Sixteen (16) firm holding contact terminals reduce the risk of power loss/fluctuation in high vibration work environments 

Battery's built-in Memory Chip communicates with the charger to maximize battery life using 3 Active Controls (Current, Voltage & Thermal) 

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. Makita DC18SD 30-60 Minute Charger The Makita DC18SD 240V Li-ion 9.6v - 18v 30-60 Minute Charger uses a CPU to communicate with the batteries built in memory chip during a charge cycle, which analyses the data stored in the battery chip to decide on the best charging method at that time. This innovative technology results in longer battery life. This charger is suitable of charging up to 3.0ah Batteries only.

Built in sounds on the DC18SD let you know charging status and completion. Makita Forced Air Cooling Fan technology cools the battery during charging by forcing cool air through the battery' s built-in air vents prolonging the life of the battery.
