Motive Power: What are H&V’s requirements for minimum order quantity?

H&V’s typical MOQ is 5,000 lbs for commercial orders.

Motive Power: What is the lead time for H&V battery separator?

Service is a cornerstone of H&V’s battery separator business. Our goal is to ship finished product in fifteen business days to all customers.

Motive Power: Why use synthetic fibers in battery separator?

Synthetics, if incorporated correctly into the separator, will increase strength properties. The synthetic fibers protect against punctures caused by plate imperfections and reduce scrap in battery assembly. Over the length of the battery’s lifespan, the vibration resistance and compression recovery is improved.

Motive Power: Are synthetic fibers stable in acid?

Choosing the correct synthetic for acid environments is critical. H&V’s selection of synthetic fibers ensures both chemical stability and proper function during the separator manufacturing process.

Motive Power: Can H&V produce globally?

H&V produces AGM battery separators across Great Britain, China, and the United States—utilizing four plant locations and five manufacturing lines. Global customers can be assured of the same product and quality regardless of its origin.

Motive Power: What is the grammage range of H&V separators?

H&V designs custom separators across all applications. If you need a specific grammage (basis weight), we can supply it. At present, our most popular grades range from 130 gsm to 490 gsm. Other weights are available on request.

Motive Power: What is the thickness range of H&V separators?

H&V is committed to match product specifications to your needs. We can supply whatever thickness your design requires. Currently, our most popular grades fall within 0.9 mm to 3.4 mm (measured with 10 kPA in accordance with BCI 3a-T4 test standard).

Motive Power: How do you test thickness?

Thickness is measured using a precision electronic caliper gauge loaded at 10 kPa pressure. 20 kPA and Japanese Industrial Standard measurement methods also available on request.

Motive Power: What is EnergyGuard®?

EnergyGuard® is a specialty brand of H&V AGM separator. EnergyGuard® separators use a special furnish composed of microglass fibers and synthetic fibers. It exhibits the full functionality of traditional all-glass separator but with unparalleled tensile and burst strength. This feature reduces the reject rate in battery manufacturing, particularly cutting back pasting-lump punctures and unwinding-related tears. EnergyGuard® experienced growth over the last five years and, today, holds a strong share in the AGM separator market place.

SLI Stop-Start: What is Start-Stop technology?

Start-Stop is a new automotive platform that turns off the car’s engine off during idling. The emissions savings that accumulate during city driving (such as sitting at a red light) can reach upwards of 5-10 percent. But it is not without challenges; frequently restarting the motor puts extreme stress on the battery. Traditional lead acid batteries have not met the challenges of Start-Stop. Automakers today have chosen AGM sealed-lead acid batteries as the battery of choice for power Start-Stop vehicles. AGM batteries are better equipped to deal with the challenges of frequent restarts and Partial State of Charge(PSoC). Across our three continental manufacturing sites, H&V is making the world’s premiere Start-Stop separator.

SLI Stop-Start: What does “PSoC” mean?

“PSoC” is an acronym for “Partial State of Charge”, referring to the demands placed on a Start-Stop battery before it reaches its full recharged state. In flooded lead acid batteries, PSoC leads to a greatly diminished cycle life. AGM batteries have allowed the automotive industry to meet these challenges. AGM lead acid attack PSoC demands by means of increased rate of charge acceptance, reduced positive-active material plate shedding, and resistance to acid stratification.
