Tests of a new acoustic system in the spring of 1982, using radio frequency transmission of the data, required the Naval Ocean Research and Development Activity NORDA to reconsider the use of lithium battery technology. A request was made to the Navy Safety Office, Naval Sea Systems Command Code 06H, for permission to utilize lithium batteries in the RD project and for permission to use existing lithium sulphur dioxide cells, which had been purchased in previous years. The Safety Office tentatively approved the intended useage but subject to a performance test and evaluation of a representative sample of the existing cells. In response to the NAVSEA direction, 32 cells wee randomly chosen and subjected to forming and discharge tests. The cells, as a group, performed beyond expectations and provided energy in excess of the manufacturers original specifications for these cells. All tests were performed without safety problems or any incidents. Similar cells from the same lot were subsequently used at sea in the RD project and performed equally as well as those tested in the laboratory. This report documents the testing procedures used to evaluate 4-5 year old LiSO2 cells and the test results achieved.
