GENUINE MAKITA BL1840 18V 4.0AH LXT LI-ION BATTERY PACK WITH STAR

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.

Makita Star Battery - 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.

Makita Star Battery - Overcharge 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.

Makita Star Battery - 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.
