SAN DIEGO, Sept. 10, 2013

SAN DIEGO, Sept. 10, 2013 /PRNewswire/ --Maxwell Technologies, Inc. (Nasdaq:
MXWL) announced today that it is supplying ultracapacitors to Caterpillar for
a high-efficiency energy management system that supports Caterpillar's
fuel-saving hydra-electric technology in the industry's largest-ever hydraulic
mining shovel, the new Cat® 6120B H FS. The 1,400-ton shovel's innovative
energy management system incorporates 98 of Maxwell's 125-volt ultracapacitor
modules to efficiently absorb energy during brief shovel movements and rapidly
deliver stored electrical energy on demand to supplement the main power


"Caterpillar's use of ultracapacitors to support this energy-saving technology
in the mining industry is a further demonstration of the versatility of our
products across an increasingly diverse spectrum of industrial and
transportation applications," said David Schramm, Maxwell's president and
chief executive officer.

Unlike batteries, which produce and store energy by means of a chemical
reaction, Maxwell's ultracapacitor products store energy in an electric field.
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 to +65C), operate reliably up to one million or
more charge/discharge cycles and resist shock and vibration. Maxwell offers
ultracapacitor cells ranging in capacitance from one to 3,000 farads and
multi-cell modules ranging from 16 to 125 volts. For more information on
