Makita 18V LXT 4.0 Ah Lithium-Ion Battery Pack
Makita continues being the innovation leader in cordless tool technology, expanding the world’s largest 18V Lithium-Ion cordless tool platform with the BL1840 18V LXT Lithium-Ion 4.0 Ah Battery Pack. The new battery is engineered for more run-time and faster charging than other 18V 4.0 Ah Lithium-Ion batteries on the market today. You can now depend on 35% more running time, and a full recharge of only 40 minutes, which is twice a faster rate than the competition. An impact-resistant outer case and shock-absorbing inner-liner will survive the demands of a harsh work environment, delivering power in the most extreme hot and cold weathers. STAR Protection Computer Controls allow the tool and battery to monitor conditions during use and exchange data in real time to protect against overloading, over-discharging and overheating, and will communicate with the Rapid Optimum Charger to optimize battery life by actively controlling current, voltage and temperature. With over 80 items in the lineup, Makita has again extended its line of 18V Lithium-Ion tools to give you unmatched breadth-of-line, power and efficiency.
