MAXWELL TECHNOLOGIES INTRODUCES COMPACT, LIGHT WEIGHT 'C-CELL' BOOSTCAPR ULTRACAPACITOR PRODUCTS FOR INDUSTRIAL AND TRANSPORTATION APPLICATIONS

ROSSENS, Switzerland - Maxwell Technologies, Inc. (Nasdaq: MXWL) announced today that it has introduced BOOSTCAPR Energy - and Power-type "C-Cell" ultracapacitor cells and multi-cell packs to provide high-performance, "life-of-the system" alternatives to batteries for a wide range of industrial and transportation applications.

Dr Richard Balanson, Maxwell's president and chief executive officer, said that the new 2.5-volt cells have the same external dimensions but weigh just one-third as much as the familiar C-size battery, and are designed for easy mounting on printed circuit boards and in other electrical devices and systems. Representative applications include industrial robotics, actuators, telecommunications power buffering and back-up, aircraft door and air bag actuation, distributed power nodes for automotive subsystems and solar energy system augmentation.

"Global demand for ultracapacitor-based energy storage and power delivery solutions is growing rapidly, and we are committed to providing the industry's most complete single and multi-cell product portfolio," Balanson said. "The new C-cell is the only product of its size and capacitance that is hermetically sealed through a double seaming process to ensure long life and
reliability."

Michael Everett, Maxwell's vice president and chief technical officer, said the 120-farad BCAP0120 P250 Power-type C-cell is engineered specifically for high-cycling applications that require the lowest equivalent series resistance (ESR) and highest efficiency, while the 140-farad BCAP0140 E250 Energy version is designed to provide more economical solutions for lighter
duty applications. Each also is available in a fully integrated six-cell, 15-volt, pack.

Other recently introduced BOOSTCAP ultracapacitor products include cells ranging in capacitance from 320 to 2,600 farads and more than 20 fully integrated packs and modules based on the new cells. All of the 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 these products are based also
significantly reduce manufacturing cost, positioning Maxwell to compete favourably with batteries and other energy storage technologies."

BOOSTCAP ultracapacitors deliver up to 10 times the power and longevity of batteries, require no maintenance and operate reliably in extreme temperatures. In transportation applications, they efficiently recapture energy from braking for reuse in hybrid drive trains, reducing fuel consumption and emissions. They also provide compact, lightweight, "life-of-the vehicle" solutions to stabilise automotive power networks and power new, all-electric subsystems, such as drive-by-wire steering. In mission critical industrial applications, where backup power is critical for continued operation or a soft shutdown in the event of power interruptions, they provide reliable, cost-effective, maintenance-free energy storage. In
wind turbine blade pitch and braking systems and other industrial applications, they provide a simple, solid state, highly reliable, solution to buffer short-term mismatches between the power available and the power required.
