Energy storage capacity (2Ah) for long run times. With overload, over-discharge and overheating protection. Star Protection Computer Controls: 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.
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 ControlsT 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 ControlsT 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 ControlsT monitor battery heat during operation. If the battery reaches a certain level of heat it will cut power to the tool. 2 x 18v LXT BL1820 2.0Ah Batteries.
