Search and rescue (SAR) beacons use a variety of lithium primary batteries. Similar electrical demand on the battery and the requirement for low temperature performance in particular are common amongst all SAR beacon batteries. They must remain inactive for many years then operate the beacon in a life or death situation-this is the essence of the reliability issue. How is reliability to be assessed? The condition of lithium batteries retrieved after five years of field use in SAR beacons was ascertained. Cell failures, inadequate battery designs, poor assembly techniques and quality control lapses were all in evidence. Studies of cells commonly used in beacons have called into question their ability to power the beacons for typical service lifetimes. Deterioration in the performance of some of the lithium products contradicted the oft-quoted '10-year shelf-life' for lithium batteries. This paper discusses: (a) the feasibility of a test to predict performance of beacon batteries; (b) preliminary results from experiments with a predictive test conducted on Li/SO2, Li/SOCl2, Li/MnO2 and Li/(CF)n cells; (c) factors identified with the degradation of reliability in SAR beacon batteries; and (d) some simple and inexpensive methods that beacon battery assemblers, cell manufacturers and others can adopt to improve the overall reliability and quality of their lithium batteries
