Order No.: JC 80 Customer's No.: X46175 Date: 27-4-1927 Re Tests on ST.13 Battery (181) This battery was removed from 9EX for bench tests after having run 3,094 miles. On low rate discharge through a constant external resistance of 1.80w, 65.5 ampere hours were realised & all 9 cells discharged equally showing positive weakness on the Cadmium test. After a full charge a high rate discharge was given through a constant external resistance of .100w. Initial amperes = 106.7 Time to 104 " = 6.3 men. " " 100 " = 10.7 " " " 90 " = 15.0 " " " 80 " = 16.3 " Signed (Cont'd) This Sheet must be filed on completion of the work. | ||
