| Contd. Extract X4617 -8- EFC {E. Fowler Clarke - Electrical Engineer} 1/T11.10.24. This battery is not of suitable dimensions for being placed in our standard battery box on the car, but on account of the good results Messrs. Fullers have been communicated with with a view to supplying us with a battery which is suitable and we have only recently received another one from them OSV12/85 - weight 90 lbs, which will go in our standard dimensions. Notes of interest concerning this battery are contained in a report JB.69 attached. We surmise that this battery may do equally well in performance on the bench tests and afterwards give good results on the experimental car. It is possible that owing to the smaller size of the battery it may not meet our specification in every respect. Exide 6NEB/1 & P & R RR.11. x4617 These batteries each of identical weight 103 lbs. are the latest forms of the standard Exide and P & R batteries arranged to suit the standard box to the best advantage, and so arranged mutually that not only are the whole batteries interchangeable but that the cells of each battery are also interchangeable, having, amongst other things, the same kind of terminals with flat nuts, making flat surface connections to kinked cell to cell connecting links, as in our standard. The batteries, of course, contain all the modifications which have been arrived at by experience. | ||
