18 Volt power stack battery using innovative pouch cell technologyCan be used in all 18 Volt XR battery machinesHas the same voltage level and comparable capacity as compared to conventional round cell batteriesMore compact dimensions due to more efficient use of space inside the battery caseLower weight through smaller cellsLower internal resistances of the cells enable a more efficient current flow and thus a considerably higher power development by up to 50% in certain applicationsLonger 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 ratioNo memory effect and the lowest self-discharge ensure trouble-free long term useOptimally suitable for the hard daily use through sturdy battery casing as well as impact-resistant soldered cellsLowest contact resistance when connecting individual cellsLarge-area contacts that are p
