For improved tool performance and extended battery life, Makita® created Star Protection Computer Controls™. Star Protection is communication technology that allows the Star Protection equipped tool and battery to exchange data in real time and monitor conditions during use to protect against overloading, over-discharging and overheating. For increased versatility, the tool can also be powered by Makita® 18 V LXT® lithium-ion batteries with the star symbol on the battery indicating Star Protection inside.
