I don't understand why you haw problem with repairing your tools in Poland.If it is cordless tools no problem,if it is power tools then depend on the voltage.I repair tools for DE Walt and Black&Decker in Bosnia and Herzegovina and haw a loot of tools from USA.All so,after the war in Peace capping forces is some USA solders and they bring tools from USA.I also haw DE 9135 charger and charging all DE WALT and old Black&Decker batteries with no problem.Somme time i have problem with sliding battery's of Black&Decker because hire is 3 pins on top,and sometimes I receive with 2 pins on top.
