X3711 Copy of a letter from Multiple Storage Battery Corpn. --------------------------------------- 350, Madison Avenue, New York City. November 25th, 1921. Messrs. H.M. Hobson Ltd., London. Gentlemen, Answering your letter of the 14th with a copy of the Rools-Royce letter of November 11th, we feel that it would be best to test our battery further, but to take into full consideration the fact of the service it has already been subjected to, in comparing it with the new batteries they have been testing. It must be borne in mind that to keep a battery at high capacity it is necessary to charge and discharge it at intervals and that it must not be left idle or sulphation will set in and care would then have to be taken to rid the plates of this condition by a slow and gradual charge until the battery is up to full capacity again. Naturally a Cadillac battery is not built for the specifications of a Rolls-Royce Automobile. It was sent over only for testing the life of the plates and was not intended for use in a Rolls-Royce car. Of course, with the specification of the battery, giving the location of the leads, the voltage and amperage and without any further test of the plates because they had been tested and found satisfactory we could naturally make up a battery suitable for a Rolls-Royce car. We claim that our battereies will give far longer | ||
