Power Technology, Inc. Announces New Battery Test Results; Power Technology's Grid Structure Delivers Higher Charge Capacity
LAS VEGAS, NEVADA--(CCN Disclosure, January 25, 2001)--Power Technology, Inc.
(OTCBB: PWTC), today announced that BC Research, Inc.'s (BCRI) Chemical and
Environmental Process Group, located in Vancouver, BC, has just released the
results of their latest eusing Power Technology's patented reticulated lead
foams employed in flooded lead-acid batteries.
These experiments were performed to assess the performance ofPower Technology's
"second generation" reticulated foam in directcomparison with the grid design
currently used in conventionalflooded, single cell lead-acid batteries.
Critical measurement criteria, such as delivered capacity;specific energy and
specific power, were normalized based upon thepaste weight in order to carry out
a straightforward comparison withthe data obtained by using other pastes such as
Bipolar Power'sproprietary lead-acid battery paste.

For definitions, see Glossary at end of release.
Correspondingly, the charging capacity per total initial pasteweight was about
90% higher for Power Technology's foam, e.g.: 20.8Ah/Kg paste as compared to
only 10.9 Ah/Kg paste for the standardgrid. This increase in charging capacity
per paste weight representsan important step forward for the Company's
second-generation gridstructure.
Test results further indicated that Power Technology's reticulatedstructure,
because of its high specific area, allows for asignificantly higher charge
capacity than a standard grid of similargeometric area.
Furthermore, the advantage of Power's reticulated lead structurelies not only in
its ability to hold a larger quantity of paste butalso in the intricate
interaction between the three-dimensional gridmatrix and the applied paste.
In its testing, B.C.R.I. employed a novel float charging protocol, modified from
standard industry practice. Using this new approach, B.C.R.I. found that
standard charging techniques "undercharged" PowerTechnology's reticulated grid.
The resulting charging protocol isreferred to as the "extended two-step float
charge." The standard gridcould not withstand the modified charging technique.
Power Technology's reticulated battery, when charged using thisextended two-step
float charge method, provided the following data:

Commented Lee Balak, Power Technology's President and ChiefExecutive Officer,
"We are energized and excited by these latest testfindings. We are continuing to
investigate and develop additional waysof increasing the power-to-energy ratio
to 20w/Wh in order to meet therequirements of the hybrid and electric vehicle
market. We will focusour efforts towards manufacturing the reticulated structure
byalternative methods so as to compete head-on with the more exoticchemistries."

Glossary:
Ah: Amp hour
Charging Capacity: applied charging current X charging time. Express in Ah.
Actual (or Delivered) Capacity: discharged (or delivered) current X discharge
time Expressed in Ah.
C-rate: the rate at which a battery with an actual (or rated) capacity ("C") is
discharged. The number represents the discharge timein hours. E.g. C/5 means the
battery was discharged for 5 hours. For a battery rated at a capacity of 100 Ah,
the discharge rate C/5 means that the battery was discharged for 5 hours at 20 A
current.
Power: Calculated as discharge current X average voltage during discharge.
Specific Power (or Power Density): the power delivered by a battery divided by
the total weight of the battery (including plates, plastic case, electrolyte,
etc.). Expressed in W/kg)
Specific Energy (or Energy Density): the energy supplied by a battery divided by
the total weight of the battery. Expressed in Wh/kg. The energy released by a
battery can be calculated as the discharge current X discharge time X average
voltage during use.
Watt = Ampere X Volt.
Wh: Watt hour
