Customer's No. After a full charge the battery was given a high rate discharge through a constant resistance of .100 w. Initial amperes = 107.0 Time to 104 " = 2.8 min. " " 100 " = 5.1 " " " 90 " = 8.5 " " " 80 " = 9.9 " All cells shewed very weak negatives on the cadmium. The Oldham & Fuller cells do not come up to our Std cells in performance & the Oldham cells have always given a very poor capacity. Signed g.f. This Sheet must be filed on completion of the work. | ||
