The 18V LXT Lithium-Ion 1/2 in. Hammer Driver-Drill (model XPH03MB) delivers a full 750 in. lbs. Of max torque, with more work and less down time for increased efficiency and productivity. It's powered by the Makita 18V LXT Lithium-Ion 4.0 Ah battery, which reaches a full charge in only 40 minutes and delivers 35 percent more run time than the 3.0 Ah battery (BL1830). For added convenience, the battery features an integrated L.E.D. battery charge level indicator. For increased durability, extreme protection technology (XPT) is engineered inside the tool for increased resistance to water and dust and improved operation in harsh jobsite conditions. It's part of Makita's expanding 18V Lithium-Ion series, the world's largest cordless tool line-up powered by an 18V Lithium-Ion slide-style battery. Makita 18V Lithium-Ion batteries have the fastest charge times in their categories, so they spend more time working and less time sitting on the charger. 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 18V LXT and compact Lithium-Ion batteries with the star symbol on the battery indicating star protection inside.
