Dear Fowler Clark, With further reference to your very interesting report of the behaviour of our cells against the Exide, I sent this correspondence to the Works and they have no particular comments to make except that they say the tests are not quite the same and it is rather difficult to base reliable conclusions when the work has not been quite equal, which I agree with. Commander Briggs tells me that in a composite battery which he had on his experimental car in France there were two of our cells and these failed in about 16,000 miles. He said we should probably be hearing from you in due course on the matter and I shall be interested to because this seems a very short distance for cells to have run and I cannot quite understand it. Yours sincerely, G.R.N. Minchin | ||
