Makita BL18302, 18V LXT Lithium-Ion 3.0Ah Battery 2-Pack Makita 18V LXT Lithium-Ion batteries charge faster and work longer than standard lithium-ion batteries, giving you and your Makita cordless tools unmatched performance and productivity for demanding applications. The Makita 3.0Ah battery (BL1830B) has a category-leading charge time of only 30 minutes, so it spends more time working and less time sitting on the charger. It also features an L.E.D. charge level indicator to monitor battery charge. Makita is the innovation leader in cordless tool technology and has the world's cordless tool line-up powered by 18V lithium-ion slide-style batteries. The BL1830B is compatible only with Star Protection tools, indicated by the Star Symbol and/or Yellow Battery Receiver under the tool. Makita 18V Lithium-Ion batteries resist self-discharge so they're ready for use even after long periods of storage. The Rapid Optimum Charger (sold separately) is a smart-charging system that communicates with the battery during charging to monitor current, voltage and temperature. This helps optimize battery life and deliver a faster charge. The Charger has a built-in fan to cool the battery for faster and more efficient charging. For improved tool performance and extended battery life, Makita created STAR Protection Computer Controls. STAR Protection is communication technology that allows the tool and battery to exchange data in real time and monitor conditions during use to protect against overloading, over-discharging and overheating. Integrated L.E.D. battery charge level indicator allows user to monitor battery charge Reaches full charge in 30 minutes or less Compatible only with Star Protection tools, indicated by the Star Symbol and/or Yellow Battery Receiver under the tool Battery delivers consistent power and run time in extreme temperatures, even in winter (-4 F/-20 C) Equipped with Star Protection Computer Controls to protect against overloading, over-discharging and over-heating Impact-resistant outer case and shock-absorbing inner-liner are engineered to protect the battery Sixteen contact terminals maintain a constant connection with the tool to help prevent power loss or fluctuation, even during high-vibration applications Battery resists self-discharge and remains ready for use even after long periods of storage Makita 18V Lithium-Ion is the world's largest cordless tool line-up powered by an 18V Lithium-Ion slide-style battery Makita technology delivers category-leading charge time so the battery spends more time working and less time sitting on the charger (charger not included) 3-year limited warranty INCLUDES (2) 18V LXT Lithium-Ion 3.0Ah Battery (BL1830B).
