| EFC4/A11.7.30 contd. -2- made to the plates to give greater clearance between these and the container walls with a view to avoiding a certain amount of bulging which we previously experienced (see item under side title "Reduced width of plates" in our report EFC9/AD9.7.30 on the 40/50 HP). The proposition generally would be distinctly better than with the present wooden case. At least we could arrange with the National Accumulator Co. to provide us with a battery so arranged and with other internal details up-to-date, and defer the question of standardisation until a later date. In regard to the position with the Chloride Co. the possibility of producing batteries in such containers having been queried with them they have answered to the effect that this is, with certain reservations regarding price as determined by quantity, quite practicable. The containers of the P & R batteries which we tested were of Dagenite, but the containers of both the P & R and the Exide could presumably be of ebonite as in the case of our present standard 40/50 HP. 6-volt units. Sheet metal battery box. We have suggested to DA.{Bernard Day - Chassis Design} and E.{Mr Elliott - Chief Engineer} that we be provided with a design for a sheet metal battery box for the 20/25 HP battery again on the assumption that we are continuing to use the 12-volt unit battery (see above). | ||
