Hi-Sep Battery Separator
Backup Power Hi-Sep for Backup Power Specifications Batteries used in standby power applications such as UPS and Telecom operate in exacting partial state of charge (PSOC) conditions over long periods of time. Hi-Sep glass fiber separators help extend battery life due to inherent advantages of high resistance to electro-chemical oxidation, high volume porosity, and a complete absence of oil leachants. Standby power separtor options in the Hi-Sep separator family come with glass mat and rib variants or a combination of both which can be configured to suit performance requirements and customer preferences.
  • Hi-Sep separators offer 50% higher oxidation resistance and are 100% absense of oil leachants.
  • Separators can be produced in leaf (Hi-Sep), sleeve (Hi-Sep PG), or roll form.


Our separator features include:
  • High electro-chemical oxidative resistance
  • High volume porosity of 72%
  • Absence of oil leachants
  • Low electrical resistance resulting in quick charge acceptance
  • Better recovery from deep discharge cycles
  • Variety of thicknesses and materials to suit battery design requirements - rib, glass mat or both
  • Sleeve variants come with an extra layer to provide protection during assembly
Hi-Sep battery separtors offer wide flexibility to battery manufactures in designing the battery to meet specific end performance requirements. With the combination of high resistance to electro-chemical oxidation and the absence of oil leachants our separators are ideally suited for high temperature, continuous cycling usage and unstable grid power supply conditions.
Engine-Starting Hi-Sep for Engine-Starting Specifications Under harsh tropical and high temperature operating conditions, motorcycles, scooters, cars and heavy duty commercial vehicles require batteries with high cranking power, long life, and resistance to oxidation. Hi -Sep battery separators meet these exacting needs with configuration options including ribs, glass mat, or both, and performance benefits to suit most applications.
  • Hi-Sep battery separators are highly resistant to oxidation, up to 50%.
  • Our separators are 100% free of oil leachants.
  • Available in leaf, envelope, or roll form for high speed automated plate enveloping.


Hi-Sep battery separators help battery manufacturers meet specific performance requirements by offering flexibility in separator design. Combined with high resistance to electro-chemical oxidation and absence of oil leachants, Hi-Sep separators are ideally suited for high temperature, high vibration operating conditions.

Features include:
  • High electro-chemical oxidative resistance
  • High volume porosity of 72 %
  • Absence of oil leachants
  • 360 degree diffusion resulting in high cranking performance
  • Low electrical resistance
  • Suitable for automated plate enveloping manufacturing with ribs and pre-laminated glass mat
  • Supplied in variety of combinations of either rib or glass mat thickness or both to suit battery design requirements
Motive Power Hi-Sep for Motive Power Specifications Batteries for motive power applications such as forklifts, manlifts, and electric vehilcles operate in demanding partial state of charge conditions over a long working life. For batteries to meet these demands seperators are needed with high porosity, low electrical resistance, high electro-chemical oxidation resistance, and quick electrolyte absorption characteristics. Hi-Sep meets these requirements and has the added advantage of being able to operate at elevated temperatures without any significant change in performance. Hi-Sep motive power separators are available to suit your requirements in configurations with glass mat, ribs, or both.
  • Hi-Sep battery separators have 20% higher porosity, 50% higher oxidation resistance, and 10% lower electrical resistance than competitive separators.
  • Available in leaf (Hi-Sep) and sleeve (Hi-Sep PG) form or in roll form for sleeving. Rib thickness is designed to suit specific customer requirements.
  • Better deep discharge recoverability.


Internal tests have shown batteries with Hi-Sep separators exhibit much better deep discharge recoverability. Hi-Sep also helps extend battery life due to high resistance to electro-chemical oxidation.

  • High electro-chemical oxidation resistance
  • High volume porosity of 72%
  • Absence of oil leachants
  • Low electrical resistance resulting in quick charge acceptance
  • Better deep discharge recoverability
  • Supplied in a variety of combinations including ribs, glass mat, or both to suit battery requirements
Hi-Sep battery separators for motive power applications offer flexibility to battery manufacturers in designing the battery to meet specific end performance requirements.
