| X87836. EFCl/T. 15th October, 1926. Messrs. Peto & Radford, 50, Grosvenor Gardens, London, S.W.1. For the attention of Mr. G.R.N.Minchin. Dear Sirs, Yesterday we had occasion to examine a customers New PhantomCodename for PHANTOM I P & R battery, of which he had made a complaint of the too frequent necessity of topping up. We found the battery badly messed up with acid on the top. The customer had been filling the battery pretty well, i.e. up to the bottom of the vent barrel, in order that he should not have to fill it so often, and it gave the appearance of the electrolyte having come out on to the top of the battery from every cell. This battery was one of the later type with the Dagenite vent holes, and we noticed that the porcelain vents were very slack in their threads, and in one particular case could not be made to grip the thread at all but was just resting in loosely, this being due to the expansion of the Dagenite vent hole. Also in that one particular case there was a crack at right angles across the threads. From this, the replacement of the porcelain vent tubes with Dagenite vent tubes would appear to be a doubtful advantage, and we shall be interested to hear your remarks in this connection, particularly as this change was made without first giving us an opportunity of testing it out. We agree that the porcelain vent tubes had their defects, but from our observations to date we are not convinced that the change to Dagenite is an improvement. Contd. | ||
