After charging or before attempting any maintenance or cleaning, unplug the charger from the power source. Pull by plug rather than cord whenever disconnecting charger.

The Makita DC18RC Charger is suitable for charging 14.4v & 18v Makita batteries. The cooling system blows cool air into the battery. As a result, high temperatures occur in the battery, so that the battery life is extended, and the charging process is accelerated. DC18RCFeatures: A great advantage of Lithium Ion technology is that it provides the user with the possibility to charge the batteries anytime, without any need to wait for their complete power deployment. A great improvement compared to older technologies like Ni-Cad The products should be sent to repair or maintenance, if the yellow warning light will frequently flash. Charging delay: If the battery is cooled down or too cold, there may be a charging delay. In this case, you should bring the battery to room temperature and try again. As a result, high temperatures occur in the battery, so that the battery life is extended, and the charging process is acceleratedAdaptive charging: The charger can perform adaptive charging to extend the battery's lifespan. In certain situations, the charger automatically searches for optimal charging conditions for the battery. The charging process may take longer than usual. The CPU built into the DC18RC charger communicates with the individual batteries and analyses its condition, the battery may have been abused by heat, overdischarging, or weathered by cycle-age. Makita Forced Air Cooling Fan technology cools the battery during charging by forcing cool air through the battery' s built-in air vents prolonging the life of the battery. Plug the battery charger into the proper AC voltage source. Charging light will flash in green color repeatedly.

Features The Makita DC18RC Li-ion 7.2 / 14.4 / 18v LXT Charger, uses Intelligent Charging Technology to control current, voltage and temperature to maximize the battery life.SAVE THESE INSTRUCTIONS – This manual contains important safety and operating instructions for battery charger. Charging delay: If the battery has cooled down or is too cold, there may be a charging delay. In this case, you should bring the battery to room temperature and try again. Cells in some other brands of batteries are not charged evenly, resulting in cells not being used completely, so workloads are decreased at a charge.
