Agreement to Provide Rechargeable Polymer Lithium-Ion Batteries for ZAP's Line of Electric Vehicles

SANTA ROSA, Calif.--April 28, 2005--ZAP (OTCBB:ZAPZ), pioneering the next generation of advanced transportation and energy technologies, announced today that the Company has signed an Agreement of Intent with Advanced Battery Technologies, Inc. (OTCBB:ABAT) to develop, manufacture and distribute electric vehicles using ABAT's Polymer Lithium-Ion (PLI) batteries. ABAT develops and manufactures its PLI batteries in its factory in Harbin, People's Republic of China.

Under the first phase of the agreement with ZAP, ABAT will retrofit a range of ZAP electric vehicles with their next-generation Lithium Polymer batteries and chargers. Initial testing shows that ZAP's three and four-wheel vehicles equipped with ABAT's battery would be able to increase the run time by three times or more over Lead-Acid batteries. The threefold increase in energy density of the PLI batteries could enable a similar threefold increase in transportation range for comparable-weight batteries, enabling ZAP's vehicles to achieve a significantly increased driving range between electric recharges.

ABAT's batteries combine high-energy chemistry with state-of-the-art polymer technology, overcoming many of the shortcomings associated with other types of rechargeable batteries. ZAP will take advantage of the high-performance features of the ABAT battery technology to further enhance the competitive advantages of their electric vehicles in the worldwide advanced transportation marketplace.

"We look forward to the weight reduction and range extension we expect from the ABAT battery technology," said ZAP CEO Steve Schneider. "Our research has indicated that another vehicle company in Japan has already found success with their technology. On our recent trip tip to China we road-tested several of their vehicles, ranging from scooters to a complete Lithium powered electric bus. We are continuing to expand our electric transportation product line at all levels, from personal to public transportation. We are also exploring the possibility of making an electric version of the Smart Car."

"The first shipment of ZAP vehicles has already arrived, and our engineering team is working to install and range-test the vehicles provided," said Zhiguo Fu, Chairman of ABAT. "We're very pleased to have ZAP as our strategic partner and we believe that our new relationship will accelerate the introduction of our advanced lithium polymer batteries into the U.S. electric vehicle market."
