LXT Lithium-Ion battery and optimum charging system produces 280 percent total lifetime work with 2x more cycles. 5x Lower self-discharge keeps battery cells active and ready for use, even after long periods of storage. Charging at any time will have no effect on the battery. Built-in shock absorbing features protect the battery. Sixteen firm holding contact terminals reduce the risk of power loss/fluctuation in high vibration work environments. Battery's built-in Memory Chip communicates with the charger to maximize battery life using 3 Active Controls (Current, Voltage Thermal). Battery suitable for all Makita li-ion LXT 18 volt machines. Some of those machines include: BDF451RFE , BDF451RFE3 BDF452RFE , BDF452REF3 BDF452Z BDF453RFE BDA350 , BDA351 BTD140RFE , BTD140RFE3 , BTD140Z BTL061RFE , BTL061Z BTW450RFE , BTW450Z BTW251RFE , BTW251Z BGA452RFE , BGA452RFE3 , BGA452Z BFR750 BFR750RFE , BFR750RFE3, BFR750Z BFR550RFE , BFR550RFE3 , BFR550Z BCS550RFE , BCS550Z BSS501RFE , BSS501Z BSS610RFE , BSS610Z BJV180RFE , BJV180Z BPB180RFE , BPB180Z BJS130RFE , BJS130Z BJR181RFE , BJR181RFE3 , BJR181Z BJR182Z LXT600 , LXT400 , LXT202 Features of the DC18RC: The DC18RC has a cooling fan and Active 3 Controls. This means that during the loading of the charging voltage, charging current, and temperature is held in the holes. 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 When used in conjunction with charging adapter ADP03 this charger offers also the possibility of charging Ni-MH slide on batteries of 9.6V to 24V batteries or when used with charging adapter ADP04 this charger offers the possibility to charge Ni-Cd and Ni-MH rod and block batteries of 7.2V to 18V batteries.
