| To EFC. from R.{Sir Henry Royce} Copy to CJ. X.604 X.979 ORIGINAL. RE X.664 BATTERIES. R7/G18/7/19. 4 21 JUL 1919 RECEIVED Thanks for discharge sheet. Every reason to go in strongly for Chloride batteries which appear good in every point we have examined them, thus - (1) Probable life. (2) Weight. (3) Capacity. (4) Internal resistance. (5) Maintenance of volts during rapid discharge. (6) Price. (7) Interchangeability with American Company. Owing to the possibility of failure in some way, I think it would be as well to let the Tudor Company bring their battery to a satisfactory finish.
