Contd. -2- EFC6/T18.12.20. We now have in addition a high rate discharge battery No.40, the performance of which, reported in our EFC3/T6.10.20, was quite good. This battery has already had a box made for it to go on the experimental car, but our difficulty at the present is that there are not sufficient experimental cars upon which to run our various batteries, and therefore these must wait their turn unless we make some other arrangement for putting these on other cars. At the moment we have in addition to special Chloride batteries on the experimental cars, a Lucas C.A.V. and a Willard, and we have waiting this H.D.E.13 P & R, and a nickel alkaline battery. In answer to your query "Do you find that batteries made by this firm have any characteristics of a desirable nature which the Chloride batteries have not?", we should think that there would be less possibility of short circuits occurring in the way they have occurred on Chloride batteries we have so far received, and they might for this and other reasons have a better life and do very well on lighting service. On the other hand, results of our high rate discharge tests would seem to show that these batteries would more readily give out if the starter motor were repeatedly operated, as is often done. In view of your enquiry, we shall endeavour, when an opportunity arises, to have this other battery, No.14, also placed on a car for test under running conditions. Contd. | ||
