| ROLLS-ROYCE LTD. INSTRUCTIONS. To: E.C.G. Order No. T.C.127. Re-Tests on PR22-GRR1-1 Battery (187) This battery has completed 11,256 miles on ISEX car in France. On low Rate Discharge through a constant external resistance of 1.30w 88.4 amperes hrs were obtained all cells showed positive weakness. After a full charge a high rate discharge was given through a constant external resistance of .100w Initial amperes = 110.5 Time to 10.4v = 16.2 min " " 10.8v " = 20.0 " " All cells showed negative weakness. The above results are a great improvement on those taken when the battery was new. Signed G.J. This Sheet must be filed on completion of the work. | ||
