Independent Testing Confirms Power Technology Batteries Are More Powerful

    LAS VEGAS, Nev.--March 8, 2001--Power Technology, Inc. (OTCBB:PWTC) announced today they have received verification from an independent testing laboratory that the advanced chemistry battery paste provided by Bipolar Power International, Inc. (Bipolar) significantly improves the performance of sealed lead-acid batteries.
    Test results show significant improvement in battery energy, capacity and life and were performed in order to confirm the validity of Bipolar's proprietary paste technology.
    "Power Technology believes that the combination of our recently patented `foam grid' technology for batteries and Bipolar's proprietary paste and battery configuration will revolutionize the sealed lead-acid battery industry," said Lee Balak, President of Power Technology, Inc. "Power Technology and Bipolar have commenced building batteries for industry evaluation and potential orders of interest. These batteries will be delivered by the end of March 2001."
    Power Technology is currently in negotiations to acquire Bipolar, who's assets include twenty-two patents for advanced sealed lead-acid battery technology. These patents cover both a proprietary bipolar battery configuration and the advanced chemistry paste. This battery technology originated at the Jet Propulsion Laboratory and the California Institute of Technology in the mid-1980's. Bipolar acquired the technology from JPL and Cal Tech in 1989 and has subsequently spent $10,000,000 to complete its development. Bipolar also maintains an 8,000 square foot laboratory in Whittier, California with 176 state-of-the-art battery testing stations. Power Technology is finalizing their due diligence on Bipolar and anticipates acquiring the company in the near future.
    Power Technology, Inc is a Las Vegas-based technology development company, which holds several patents in the power generation and power storage fields, and is working to provide innovative and practical battery technology solutions for commercial, government, and industrial applications worldwide.
