Brand New!! Makita 18-Volt lithium-ion is the worlds largest cordless tool line-up powered by 18-Volt lithium-ion slide-style battery. At the heart of the LXT Series are the 18-Volt LXT lithium-ion battery and the efficient Rapid Optimum Charger. The new 18-Volt lithium-ion dual port rapid optimum charger (DC18RD) charges 2 batteries simultaneously, giving tool users unparalleled charging efficiency so their batteries spend more time working and less time sitting on the charger. The 18-Volt Dual Port Rapid Optimum Charger offers key advantages for Makita 18-Volt lithium-ion cordless tool users. The exclusive built-in fan cools the battery by forcing air through the battery's air vents during the charging process for faster charging. The charger communicates with the battery's built-in chip throughout the charging process to optimize battery life by actively controlling current, voltage and temperature. The result is category-leading charge times: two 18-Volt Compact lithium-ion 2.0 Ah batteries in only 25-minutes; two 18-Volt LXT lithium-ion 3.0 Ah batteries in only 30-minutes; two 18-Volt LXT lithium-ion 4.0 Ah batteries in only 40-minutes; two 18-Volt LXT lithium-ion 5.0 Ah batteries in only 45-minutes.
