These seven notebooks were used primarily from 1914 to 1916, although one book was used as late as 1919. The majority of the entries are by Harold H. Smith, chief of the Battery Research Department of Thomas A. Edison, Inc. The books contain data on battery cell tests performed at Edison's request. Some notes indicate an experiment number, a tube number, and different preparations of iron or electrolyte. There are a few comments by Edison and other evidence of his oversight, including mention of Edison as the person who "cuts out" the cells being tested. Also included are experiments relating to efforts to regenerate used storage battery components, such as pockets or tubes. Much of the work in these books is summarized, tabulated, or described in N-14-04-26 and N-14-12-03, Notebooks by Edison.
The one selected book contains several notes by Edison with no clear summary in his own notebooks.
