| To R.{Sir Henry Royce} & E.{Mr Elliott - Chief Engineer} from E c. CJ. & PN.{Mr Northey} c. Hn.{F. C. Honeyman - Retail orders} & Ey. c. Da.{Bernard Day - Chassis Design} & EP.{G. Eric Platford - Chief Quality Engineer} c. EWT. for R.R. Inc. ORIGINAL X.664 - BATTERIES. Further to our EFC3/T6.10.20, further batteries have now completed our preliminary routine tests. The results of these tests are given on the accompanying table of performances, called page 5, which may be considered a continuation of sheets previously issued under cover of our EFC1/T18.5.20 and EFC3/T6.10.20. Results for continuous high rate discharges of these six batteries are given on the curves on sheet H.{Arthur M. Hanbury - Head Complaints} The results for intermittent high rate discharges are given as curves on sheets I & J: Sheet I being for discharges of 15 seconds on contact and 15 seconds off; J being for 15 seconds on and 45 seconds off. The same remarks regarding these curves apply as were given in our EFC1/T18.5.20. Results for the low rate discharge tests on the recording voltmeter are also given as before. Battery No.57.R.R. Tudor 1. Two of these batteries were received. One was taken to pieces and a cell sent to R.{Sir Henry Royce} for his inspection. Details of the construction of these batteries were reported in our EFC3/T7.3.21. The other battery (No.57) has done fairly well on the tests, though the ampere hours per pound are poor. This battery will be put on an experimental car as soon as possible. Contd. | ||
