Daramic® EFS™

Daramic’s new lineup of separators are specifically designed to support start-stop vehicle battery work requirements, enabling battery manufacturers and automotive OEMs to deliver reliable battery power for users of start-stop vehicles.

Features:

  • Advanced polymer structure for improved electrical performance, while maintaining superior strength
  • Porosity increase, up to 6%, versus standard polyethylene separators
  • Lower electrical resistance in the battery yields more power
  • Reduces potential of falling below minimum voltage levels, which helps to maintain positive vehicle perception
  • Optional feature for reduced water loss

Benefits:

  • 44% longer duration to minimum voltage versus standard separators at -18 degrees C
  • On average after 30 days, maintains 4.4% higher battery power rating versus standard separators
  • 25% reduction in separator electrical resistance results in lower battery internal resistance (0.15 to 0.2 m-ohms) at -18 degrees C
