DuraLife®

DuraLife® is a new, high performance polyethylene battery separator specially designed for starting, lighting and ignition (SLI) lead-acid batteries. DuraLife’s patented design significantly improves battery performance, improves efficiency and yield during battery assembly, and reduces puncture shorts.

Features:

  • Excellent for high under hood temperature applications
  • Oxidation resistance is improved by 40%
  • Leachable organic carbons are reduced by 50%
  • Electrical resistance is 10% lower than comparable polyethylene separators
  • Patented negative cross-rib design increases separator strength
  • Available in a wide range of automotive profiles and sizes
  • Approved for use in aftermarket and OEM battery applications

Benefits:

  • Extends battery life by up to 25%
  • Battery water loss reduced by over 40% for antimony alloys and over 20% for non-antimony alloys
  • Improved enveloper runnability; rejects reduced by up to 60%
  • Envelope punctures are reduced by more than 50% when used with expanded metal grids
