Makita BL1850-2 18-volt LXT Lithium-Ion 5.0Ah Battery Review

The Makita BL1850-2 18-volt LXT Lithium-Ion 5.0Ah Battery, 2-Pack is designed to outperform standard lithium-ion batteries. With a category-leading charge time of only 45 minutes, this battery spends more time working and less time sitting on the charger. The 18V LXT 5.0Ah battery is compatible only with Star Protection tools, indicated by the Star Symbol and/or Yellow Battery Receiver under the tool. The Makita Rapid Optimum Charger (sold separately) is a smart-charging system that communicates with the battery during the charging process to monitor current, voltage, and temperature. This advanced charging technology helps optimize battery life and deliver a faster charge. Additionally, the battery delivers constant power and run time in extreme temperatures, even in winter (-4°F/20°C). Impact-resistant outer case and shock-absorbing inner liner protect the battery from accidental drops and bumps. 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. The Makita 5.0 Ah battery provides up to 65 Percent more run time per charge compared to the 18V 3.0Ah battery (BL1830).
