Ultralife Batteries, Inc. (NASDAQ: ULBI) announced that it will relocate its McDowell Research communications accessories manufacturing operation from Waco, Texas, to Ultralife's facilities in Newark, New York. The target date for completing the move of the operation is Sept 30, 2007. Production work will transition to New York between mid-July and mid-September.

?This was a very difficult but necessary decision, particularly considering the dedication, talent and hard work of our Waco employees. We greatly appreciate their work and accomplishments and will be working closely with local Waco officials and agencies to provide assistance in helping our employees transition to other jobs,? said John D. Kavazanjian, Ultralife's president and chief executive officer. ?While our McDowell Research products continue to be extremely popular with our customers, and are in high demand, unfortunately the Waco operation has not achieved the profitability that we had planned.? Kavazanjian concluded, ?This move will enable us to realize the operational efficiencies and profit enhancements envisioned when we acquired McDowell Research last year.?

Approximately 100 employees will be affected. Ultralife is working closely with McDowell Research customers and suppliers to achieve a smooth transition. No significant charges are anticipated at this time as a result of this action.
