Makita DC18RD Powerpack

Makita LXT is the cordless tool system powered by 18V lithium-ion slide-style batteries. The 18V lithium-ion dual port rapid optimum charger (DC18RD) charges two batteries at the same time, giving tool users unparalleled charging efficiency so their batteries spend more time working and less time sitting on the charger.
The 18V dual port rapid optimum charger offers key advantages for Makita 18V 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.
