ENTEK LR enables battery makers to meet tough OEM requirements for the next generation of EFB batteries, delivering the highest cold-cranking performance of any polyethylene separator and outstanding battery cycle life. Combining ultra-low electrical resistance and maximum durability, ENTEK LR is the world’s most advanced battery separator.
ENTEK LR has been extensively tested in EFB battery designs. The results of those tests confirm that ENTEK LR provides superior battery performance.
ENTEK LR was formulated and engineered to:
- Prevent shorting and dendrite growth between electrodes
- Have higher porosity and lower tortuosity
- Facilitate more ionic conduction
These properties give ENTEK LR the lowest electrical resistance of any battery separator on the market today.
ENTEK LR Separator maintains wettability even after being boiled in water and dried multiple times. Unlike competitive offerings, ENTEK’s wettability is engineered into the separator. The low electrical resistance and increased cold cranking amps offered by ENTEK LR will last for the entire life of your battery.
Delivering Results in EFB Batteries
Batteries Built with ENTEK LR Separator Have:
Lower Internal Battery Resistance
Improved Cold Cranking
EN U10: Increased by 100 to 300mv
Lower Internal BEN U30: increased by 60 to 140mv
ENTEK laminates glass fiber 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.
The GE profile is the best combination of cost savings 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 0.15mm backweb GE profile is the world’s standard for robust, high-performaning, cost-effective battery separators. GE is available in .15, .20 and .25 backwebs.
