OUR REF M {Mr Moon / Mr Moore} /5. 7th September 1926. Messrs. Rolls Royce Ltd., DERBY. For the attention of Mr. Fowler Clark. Dear Sirs, We are in receipt of yours of the 2nd inst. about topping up with acid and have discussed this with our Works. We consider that P. & R. {Sir Henry Royce} batteries required more frequent topping up than the Exide because there was a less volume of electrolyte in the P. & R. {Sir Henry Royce} cells. We think there can be no doubt that the cells in question are probably fitted with .6 m {Mr Moon / Mr Moore} /m ebonite and single ribbed wood separators as we only commenced supplying the double ribbed wood and .4 m {Mr Moon / Mr Moore} /m separators about August 1st this year. In these later batteries there is much more volume of electrolyte. The writer has been paying particular attention to the topping up of the battery on his car and it seems to be behaving quite normally from this point of view and much the same as an Exide which he had on previously. Incidentally, while the Exide battery was on his car the platinum points on the battery ignition had a shorter life than any other set of points, so it does not look as if the battery has very much to do with the life of these points. Yours faithfully, PETO & RADFORD. g. {Mr Griffiths - Chief Accountant / Mr Gnapp} R. {Sir Henry Royce} N. Minchin Eoud. | ||
