Date: 15-10-1926 Order No. JC45 Customer's No. X4617S Re Test on S1 battery (154) This battery was taken off 5EX for bench test. It was given a high rate discharge through an invariable external resistance of .100w & the result was very good. The initial amperes were 109.2 Time to 1.04" = 3.0 mins " " 1.00" = 12.8 " " " .90" = 17.9 " " " .80" = 19.0 " This result is much better than when discharged approx. 15 months ago. All cells were of equal voltage during discharge & showed negative weakness on the cadmium. The battery has run 1654 miles. Signed: GJ This Sheet must be filed on completion of the work. | ||
