If cracks develop in the sealing compound as they have done to a considerable extent in one of the batteries, the electrolyte sometimes has a habit of creeping out through these cracks and I believe in some cases gives one the impression by running down the outside of the cell and through the bottom of the case, that one of the cells of the battery is leaking. So far as our experience goes a very soft sealing compound and one which is plastic enough to 'give' rather than crack is the better proposition. Yours faithfully, | ||
