Makita’s 18V & 14V batteries have a built in memory chip that records the battery usage history. While the battery is connected it will transmit the data to the charger

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. 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-CadSAVE THESE INSTRUCTIONS – This manual contains important safety and operating instructions for battery charger. As a result, high temperatures occur in the battery, so that the battery life is extended, and the charging process is accelerated 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. 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.

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. Built-in CPU - gathers information from the battery's memory chip to determine optimum charging method The DC18RC can charges a BL1830B 18v LXT 3.0Ah battery in approximately 22 minutes - and to the fullest charge.This means that during the loading of the charging voltage, charging current, and temperature is held in the holes Adaptive 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. Conditioning charge can extend the life of battery by automatically searching the optimum charging condition for the batteries in every situation. The battery employed in the following conditions repeatedly requires "conditioning charge" to prevent fast wear out. In that case, yellow light lights up. Adaptive charging: The charger can perform adaptive charging to extend the battery's lifespan. In certain situations, the charger automatically seeks optimal charging conditions for the battery. The charging process may take longer than usual.

The Makita DC18RC battery charger always lights up red/green and the battery cannot be charged. There are several possible causes for this problem: 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. 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. To keep your batteries running at their best, the DC18RC has a forced cooling system to prevent overheating which will give your batteries a longer service life. Sold as a single unit. Make sure cord is located so that it will not be stepped on, tripped over, or otherwise subjected to damage or stress.Digital power display with 3 active charging colours identifies the condition of the battery and charging condition With finish of charge, the charging light will change from red one to green one and the melody sound or buzzer sound (a long beep) comes out to notify completion of charge. Built-in cooling fan system that blows cool air into the battery, which keeps the battery cool during the charging process. This helps to extend the overall battery life and accelerate the charging process The cooling system blows cool air into the battery & as a result when high temperatures occur in the battery it cools the battery so the life of the battery is extended + the charging process is accelerated as well.

Plug the battery charger into the proper AC voltage source. Charging light will flash in green color repeatedly. Makita’s 18v & 14v batteries have a built in memory chip that records the battery usage history. While the battery is connected it will transmit the data to the charger Makita Lithium-ion battery chargers evenly charge throughout all the cells in the battery, on discharging the battery draws evenly resulting in an optimum charge. Before using battery charger, read all instructions and cautionary markings on (1) battery charger, (2) battery, and (3) product using battery. The followings show the symbols used for the equipment. Be sure that you understand their meaning before use.

Not Right? Try One Of These Instead

To reduce risk of injury, charge only Makita type rechargeable batteries. Other types of batteries may burst causing personal injury and damage. 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:
