Tech Team's Positive Terminal Cable feature a 10mm – 3/8” diameter tinned double crimped 100% copper lug terminal end with a protective heat shrink polyolefin sleeves to prevent moisture incursion and eliminate corrosion and a military grade 19mm lead top post terminal with a 100mm accessory lead. When it comes to battery cables the LOWER the AWG number the HIGHER the current carrying capacity. Tech Team's #2 AWG cables carry far more current than other #4 AWG, #5 AWG, or #6 AWG (do not even think about #8 AWG) cables. This means less heat buildup and less voltage / amperage drop which prolongs the life of starters, inverters, motors, and other connected electrically powered devices. The product comes with one (1) red 36 inch #2 AWG 100% copper stranded wire top post positive terminal battery cable, a 100mm accessory lead, and a 100% copper 3/8” diameter tinned lug terminal end with heat a shrink protective sleeve.
