DEWALT DCBP518G-XJ Tool battery 18 V 5 Ah Li-ion

18 Volt power stack battery using innovative pouch cell technology. Can be used in all 18 Volt XR battery machines. Possesses the following advantages as compared to conventional round-cell batteries at the same voltage level and comparable capacity: Lower inner resistance of the cells enables a more efficient current flow and thus a considerably higher power development by up to 50% in certain applications. Longer service life and thus higher number of charge cycles thanks to more efficient temperature control as well as improved heat dissipation thanks to the large, even outer shape of the cells and the optimum surface/volume ratio. No memory effect and the lowest self-discharge ensure trouble-free long term use. Optimally suitable for the hard daily use through sturdy battery casing as well as impact-resistant soldered cells. Lowest contact resistance when connecting individual cells. Large-area contacts that are protected against accidental short-circuits. Housing made of chemical and fuel-resistant an...
