Dear Fowler Clark, I am now back and was down at the Works the other day and am glad to find the progress we are making with regard to lowering your charging voltage. I saw one of the latest R.R.11 cells with the Dagenite moulded lids, the increased height of the cells with ½" more sludge space, thicker ebonite separation and the edge of the box cut away under the handles. The battery looks very smart and I think that these represent a considerable improvement over anything previously supplied and I feel certain that they must give a longer life. Yours sincerely, G.R.N. Minchin | ||
