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.
