Order No.: JE119 Customer's No.: X46175 Date: 17-8-1928 Re Failure of Fuller cell in SZ Battery(17) No 1 cell failed in this battery after having run 10000 miles + 2 years on our bench life test. The negative plates were good. The positive plates had lost a large amount of paste + the grids were intact but very frail & easily crumbled. The wood & ebonite separators were good. Moulded U strips of hard rubber were fitted over the edges of the positive plates to prevent shorting by buckling of the plates. I do not consider these should be necessary if the wood & ebonite separators were of a good size & overlapped the plates slightly. The cause of failure was due to accumulated sediment which reached up to the plates causing a short. Signed: G.J. This Sheet must be filed on completion of the work. | ||
