Testing of high gravity flooded batteries for high rate utility applications

Standard gravity (1.215 Specific Gravity) List 1S Round Cells were converted into high gravity (1.300 SG) List 1SH cells. Initially three cells were converted to high gravity and tested in the laboratory for suitability in power utility applications. Since the results were promising, two strings were produced at the factory and tested. After the cells met the acceptance criteria they were installed in a nuclear generating station and tested. The test results show that List 1SH high gravity Round Cells are well suited for power utility applications
