It is understood to be generally advantageous that accumulators should be fitted up in ebonite boxes and have wooden separators. We understand that the Chloride Cells we are buying are so fitted. I should very much like, if possible, for there to be some experiments made to shew the average rate of loss of charge by leakage in the ordinary car accumulator. This information would be very useful to PN.{Mr Northey} I should suggest cutting off of a car accumulator from all sources of supply and discharge, and finding out how long it held its discharge, then properly insulating each cell separately and finding out how long it would retain its charge.
