ENTEK PE for SLI
Starting, Lighting, and Ignition (SLI)
SLI battery manufacturers demand separators that provide excellent cycle life, strong durability, and low electrical resistance for every weather and road condition.
ENTEK has embraced start-stop technology with separator technology that supports the fast-charging, high electrical load performance that start-stop batteries must deliver.

This data sheet only shows typical properties. These typical properties may change without prior notification. We urge purchasers to conduct tests to determine final suitability for their specific end uses. No statement with respect to use is intended as a positive recommendation for such use, no guarantee of performance expressed or implied is made.
ENTEK laminates 0.2 mm, or more often 0.4 mm fibre glass retainer mat to the positive side of the separator for high-vibration batteries using an acid resistant adhesive.
A separator profile consists of its backweb thickness, overall thickness and width plus the design and layout of the ribs. Each profile gives different performance and use characteristics. Three of the most common SLI separator profiles are listed below. Click here to find an ENTEK representative to discuss your separator requirements.
The GE profile is the best combination of cost saving rib design along with a superior plate puncture resistant shoulder design to give customers the best of both worlds…cost optimization and high-performance batteries. The 0.15 mm backweb GE profile is the world’s standard for robust, high-performing, cost-effective battery separators. GE is available in .15, .20 and .25 backwebs.
ENTEK GE Brochure
Our most robust rib design for battery applications requiring thicker separator backwebs and closely spaced ribs. The RR profile has 20 major ribs in a standard width separator.
For customers looking to have a cost optimized solution, MR profile substitutes mini ribs for major ribs compared to the RR profile, while using a time proven shoulder design to minimize shoulder plate puncture.
