After a good charge a high rate discharge was taken through an invariable external resistance of .100w Initial amperes = 106 Time to 104 " = 4.3 min " " 100 " = 9.5 " " " 90 " = 12.6 " " " 80 " = 16.6 " Negative weakness was shown on the Cadmium. All cells discharged equally. The above results may be considered good having done so much work. Signed E.J. This Sheet must be filed on completion of the work. | ||
