Our experience with threaded rubber separators in Willard and CAV-Willard batteries has been such as to indicate that these would make very satisfactory separators for our standard batteries. In batteries which we have opened up containing such separators, we have found almost invariably the separators in first class condition, and we have never known of a case of short circuiting through such separators, or any suggestion of failure to separate elements correctly. We have also certain experimental evidence to the effect that the internal charging and discharging resistance of batteries with these separators is low, (almost certainly lower than would be in similar batteries with our standard separators), though we have in the nature of things had no opportunity of making direct comparative tests. Technically, therefore, we are very keen to try standard batteries containing these separators. There have been in the CAV. batteries various other faults of such a nature, however, as not to condemn the separators, and therefore the experience of the separators prolonging the life of the battery has not been possible. In other words, the separators have easily outlived the rest of the battery, failure in most cases being due to disintegration of the positive plates. | ||
