Hanbury - Head Complaints} 22. 5. 22. since EFC has returned to Derby we have been able to discuss the various points raised in your memo Ps9/JP. 18. 5. 22. I would like to point out to start with that all the batteries fitted to "O" Series chassis had the following improvements:- (a) More flexible connections between the cells. (b) Long stay bolt between the sides of the containing case to prevent vibration. (c) Perforated Ebonite Separators between the wooden separators and the positive plates. In addition to the foregoing, chassis coming under "P" Series have the following improvements:- (a) Independantly supported positive and negative plates to prevent slight disintegration from causing short circuits. (b) Wooden separators which project on all sides beyond the edges of the positive and negative plates. (c) The corners of the plates rounded. (d) The negative plates made slightly thinner. (e) Improvement in lugs and the method of passing same through the cell lid.{A. J. Lidsey} (f) Partial "sealing in" of all cells at the top to obtain increased rigidity. From the foregoing I think it will be plain that we had not allowed matters to drift at Derby and that as soon as certain troubles were experienced in service we laid ourselves out to improve the product. As mentioned in my last memo, we held a Conference between our Technical people at Derby and representatives of the Exide Company with the object of discussing the troubles which had developed in | ||
