This battery was taken off the car for test owing to it having discharged whilst standing. The results are as follows: Low Rate Discharge through an invariable external resistance of 1.80w. Ampere hours realised = 95.6 this discharge was taken after the battery had stood for 3 days. High Rate Discharge through an invariable external resistance of .100w Initial amperes 111. Time to 104 amperes = 11.4 min " " 100 " = 13.0 " " " 90 " = 14.2 " " " 80 " = 15.0 " Signed Kontoff This Sheet must be filed on completion of the work. | ||
