The Thomas A. Edison Papers Digital Edition

This undated notebook was probably used by Edison in October 1914. Some of the entries are continuations of experiments in N-14-12-03. Others overlap with work in N-14-10-10.1 or fill in missing experiment numbers from that book. The notes pertain to experiments aimed at the rejuvenation or "regeneration" of used storage batteries. Included are the results of tests performed on cells constructed with various regenerated components. Some entries involve the use of regenerated negative electrode "pockets," while others relate to regenerated positive electrode "tubes." The experiments bear numbers from 231 to 403, but not all numbers in the sequence are represented and the entries are not always recorded in numerical order. The front cover is labeled "Data Cell Regeneration Cadmium etc. Important." The front flyleaf is inscribed "Regeneration #3," indicating a connection to N-14-10-10.1. The pages are unnumbered. Approximately 55 pages have been used.
