Battery waste of as filler was mixed with Epoxy Resin and Polyamide at the preparation of electrically conductive paint coating, which led to enhancement of their electrical-mechanical properties. In this study, only the optimized mixing ratio and particle size was used in the preparation which determined from experiments of mixing ratio and particle distribution analysis. The grinding process, particle analysis distribution, electrical resistivity, macrostructure and adhesion of the conductive paint test have been carried out using Grinder, Sieve Machine, Mnltimeter and Revetest Scratch Tester. Optimized particle size of filler was used in the study is 150 microns and optimum mixing ratio between Epoxy Resin and Polyamide is 1:1. The mixing ratio choose because has fast curing time and good mechanical properties. The electrical resistivity decreased as the concentration of filler increased, from the result the maximum value was 24.13 x 106 n at 40% of carbon electrode (CE) filler. The adhesion properties of the paint decreased as concentration of filler increased, while the dispersion of filler in the conductive paint became better with the increased of filler. Between the three fillers CE, CW and MIX used in the study, CE filler has the best mechanical and electrical properties. IV
