SAN DIEGO, June 11, 2014

SAN DIEGO, June 11, 2014 /PRNewswire/ --Maxwell Technologies, Inc. (NASDAQ:
MXWL), a leading developer and manufacturer of ultracapacitor-based energy
storage and power delivery solutions, announced the latest addition to its K2
series of ultracapacitor cells. The new 2.85-volt, 3400-farad ultracapacitor
cell increases the range of available specific power and stored energy in the
industry-standard 60 mm cylindrical "K2" form factor, and introduces DuraBlue
Shock and Vibration Technology, the newest innovation in ultracapacitor
reliability and performance. DuraBlue Technology is tested to some of the most
demanding environmental requirements for transportation, increasing vibration
resistance by approximately 300 percent and shock immunity by 400 percent when
compared with ultracapacitor-based competitive offerings.

Enabling Energy's Future

James Hines, research director of Gartner, wrote, "The high costs and adverse
environmental impacts of consuming petroleum-based fuels are driving
development of alternative fuels and higher efficiency automotive powertrains.
These systems require a source of electrical energy, and batteries have been
widely used for energy storage in these applications; however, while batteries
can store relatively large amounts of energy over a long time period, they are
limited in their ability to deliver high power to a load. Ultracapacitors are
capable of releasing electrical energy at high power levels, and they can
accept a high rate of charge, making them an ideal complement to batteries in
high-power applications."^1

"This latest addition to our widely popular K2 Series of ultracapacitor cells
reflects Maxwell's commitment to continuous customer-driven innovation, and
delivers superior performance with unmatched reliability and value," said
Franz Fink, Maxwell's chief executive officer. "Our new DuraBlue Advanced
Shock and Vibration Technology combines Maxwell's unique and patented dry
electrode formation and manufacturing process with a robust proprietary cell
structure design to meet or exceed the most demanding shock and vibration
requirements of the growing number of power-hungry applications in global
transportation markets."

Unlike batteries, Maxwell ultracapacitor products store energy in an
electrical field that is larger than that of a capacitor – meaning
ultracapacitors have greater energy storage capacity than capacitors. This
electrostatic energy storage mechanism enables ultracapacitors to charge and
discharge in as little as fractions of a second, perform normally over a broad
temperature range (-40 degrees to +65 degrees C), operate reliably in hundreds
of thousands or more duty cycles and resist shock and vibration. Maxwell
offers ultracapacitor cells ranging in capacitance from one to 3400 farads and
multi-cell modules ranging from 16 to 160 volts, which have proven to deliver
high power, whether used alone or paired with batteries, in a variety of
applications from automotive or industrial to consumer electronics,
transportation and beyond.
