| Contd. -4- EFC2/T6.9.20. consists in providing the bottom of every plate with two lugs but that the pairs of lugs of the negative plates form two separate rows from those of the positive. There are four ebonite bridges on the bottom of the cell so that the negative plates are supported by one pair and the positive plates by a different pair. There is also a little more space allowed at the sides so that the wooden separators are allowed to overlap the plates more completely. The modification at the bottom of the plates it is intended to carry out on the batteries supplied to us, but in order to allow the separators to overlap the plates more completely at the sides, it would be necessary to increase the width of the box by a small amount. We were, therefore, asked if we could accept this small alteration by which the battery would be slightly wider. (by .125”) We find our battery box would easily take this making use of thinner packing. As an alternative to the above, which they would like us to adopt more particularly from their own point of view, they suggested that we use their XC type of battery which is altogether wider and would take up more width on the running board. This of course would have the improvements both at the sides and bottom, referred to above, and batteries of this type could be quickly supplied. They would be similar to the battery being used on the Ford cars, with the exception that both the positive and negative plates would be one stage thicker than those. The battery would be also somewhat deeper. The question of renewals would have to be considered. Contd. K 'B' 3287 (100 L) (2' C' QN' 18-3-20) C 3018 | ||
