Maxwell Technologies unveils a new "Quick-Turn" BOOSTCAP® ultracapacitor module program

New Program Offers 14-Day Turnaround for Custom Configurations to Support Systems Requiring Up to 540 Volts

San Diego, CA — Maxwell Technologies, Inc. (Nasdaq: MXWL) today unveiled a new "Quick-Turn" BOOSTCAP® ultracapacitor module program that offers shipment within 14 days of receipt a customer purchase order for custom-configured multi-cell energy storage and power delivery solutions for systems requiring up to 540 volts.


Dr. Richard Balanson, Maxwell's president and chief executive officer, said that the Quick-Turn program leverages standard modular building blocks and proprietary balancing, monitoring and thermal transfer technologies to establish a new industry standard for flexibility and responsiveness to customer requirements.

"Global demand for ultracapacitor-based solutions is real and growing, and we continue to move aggressively to capitalize on Maxwell's technology leadership to become the supplier of choice for transportation and industrial manufacturers," Balanson said. "By eliminating the complexity and long lead times that system designers frequently encounter when they want to evaluate and prototype ultracapacitors solutions, we are facilitating and accelerating development of new applications that have the potential to drive high volumes in the years ahead."

Michael Everett, Maxwell's vice president and chief technology officer, said that custom Quick-Turn modules based on the BCAP2600 2,600-farad Energy and Power cells are immediately available, and that additional options based on the entire MC family of products, ranging from 650 to 3,000 farads will be phased in, beginning in the third quarter. Quick-Turn module pricing will be quoted on a fixed fee basis for quantities of one to five units.

Maxwell also offers a complete line of standard, 15- to 48-volt multi-cell packs and modules based on the company's Power- and Energy-type ultracapacitor cells. Both standard and Quick-Turn modules are encased in rugged, splash-proof aluminum chassis and include internal cell balancing that give designers "plug and play" solutions, plus module-to-module balancing that makes them versatile building blocks for systems with higher voltage requirements.

All BOOSTCAP cells with a capacitance of 650 farads or greater operate at 2.7 volts, enabling them to store more energy and deliver more power per unit volume than any other commercially available ultracapacitor products.

"All of these products meet or exceed demanding transportation and industrial application requirements for both watt-hours of energy storage and watts of power delivery per kilogram and will perform reliably for more than one million discharge-recharge cycles," Everett said. "The proprietary architecture and material science on which BOOSTCAP products are based also significantly reduce manufacturing cost, positioning Maxwell to compete favorably with batteries and other energy storage technologies."
