Makita is a leading innovator in cordless tools with the world’s largest system powered by 18V Lithium-Ion slide-style batteries, as well as an expanding system of compact 12V max CXT solutions. For users of both the 18V and 12V systems, Makita offers increased convenience with the 18V LXT/12V max CXT Lithium-Ion Rapid Optimum Charger. The DC18RE will charge 18V LXT and 12V max CXT slide-style batteries, and shares many of the same efficiency features of Makita's groundbreaking LXT charging system. The DC18RE has a built-in fan to cool 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. In addition, the DC18RE is engineered to optimize battery life by actively controlling current, voltage, and temperature during charging. The result is category-leading charge times. For Makita 18V LXT batteries, the DC18RE will charge a 2.0 Ah battery in only 25 minutes, a 3.0 Ah battery in only 30 minutes, a 4.0 Ah battery in only 40 minutes, a 5.0 Ah in only 45 minutes, and a 6.0 Ah battery in only 55 minutes. For 12V max CXT slide-style batteries, the DC18RE will charge a 2.0 Ah battery in only 30 minutes and a 4.0 Ah battery in only 60 minutes. The DC18RE is a sequential charger and will charge one battery at a time.
