    Are lead-acid batteries good for the environment?

    The high recycling rates associated with lead-acid batteries dramatically reduce any environmental impacts. In terms of global warming potential, the environmental advantage of improved and advanced technology lead-based batteries during the use phase far outweighs the impacts of their production.

    What is a lead battery LCA?

    The lead battery LCA assesses not only the production and end of life but also the use phase of these products in vehicles. The study demonstrates that the technological capabilities of innovative advanced lead batteries used in start-stop vehicles significantly offset the environmental impact of their production.
