The proposed paper will focus on the Air Force's effort that will increase reliability and maintainability and substantially decrease, if not eliminate, the cost of maintaining aircraft battery systems. This effort is recognized throughout the military services, (Army, Navy, and Air Force), and with most of the major aircraft battery manufacturers as the Tiger Team. The Tiger Team began approximately two years ago. The goal of this team is to eliminate battery flight line maintenance shops. The battery that is currently used in most aircraft, vented nickel-cadmium, requires frequent flight line maintenance. This procedure is very costly and time consuming. The proposed paper will overview battery technologies that are being considered for a replacement of the conventional vented nickel-cadmium aircraft battery technology. This overview will also look briefly at the history of aircraft battery systems and how aircraft battery systems arrived at their current status.
