There is a growing worldwide concern regarding the environmental aspects related to the performance of a corporation and its products, whether by consumer demand or government requirements. The constant pressure for innovations and improvements related to sustainable development are current issues in everyday life of any institution that seeks to consolidate a position of acceptance and competitiveness in the global market.The automotive industry is one of the markets more involved and challenged to the demand of the environmental requirements in regards the limits of pollutant emissions and consequently fuel consumption.The European and North America vehicles already have more electrical content inside (either related to safety and comfort or even needs related to weather), which results in significantly higher consumption levels than traditionally observed in Brazil's application. This divergence challenges the Brazilian automakers and their suppliers to develop appropriate and local solutions to the demands of emerging markets.This paper aims to present the studies performed with several Lead Acid battery technologies available for application in Stop-Start vehicles in the Brazilian market. Brazil is the largest automobile market in Latin America and is positioned as 4th largest in the world market (according to 2011, Jatto Dynamics). With significant growth prospects in the coming years, Brazil has consolidated not only as consumers, but as reference in development of solutions to suit the reality of emerging countries. The Brazilian environmental regulations trends to international level, this challenges the automakers to adopt new emerging technologies and adapts others to ensure a good balance of cost-benefit.
