The new 18V Lithium-Ion Rapid Optimum 4-Port Charger, model DC18SF, from Makita will accommodate up to four 18V LXT® Lithium-Ion batteries. Two controllers to direct charging energy to the battery result in charging times of 60 minutes for two 18V LXT 3.0 amp hour batteries and 120 minutes for four LXT batteries, with 30 minutes for two 18V Compact 1.5 amp hour batteries and 60 minutes for four Compact batteries. The DC18SF features the “Active 3 Controls” battery monitoring technology: during the charging process, the charger communicates with the computer chip inside each battery to monitor current, voltage and temperature to achieve an optimum charging process for faster charging and longer battery life. Indicator lights provide updates on the charging status of each battery. The DC18SF is currently selling for around $170.
