| Contd. -3- Weight complete as delivered. Length. Breadth. Height. Tudor.C.L.G.9 82 lbs. 18¾ 5¾ 7½ Tudor C.L.G.7 63 lbs. 15 5¾ 7½ The above weights include the boxes in order to bring them into line with the other weights already given, which in every case include the complete battery as sent in by the makers. The dimensions are those of battery alone. It appears that whatever battery is used there will have to be a box or case either belonging to, or being part of, the battery itself, in addition to the battery box which is made by us and fixed to the running board. In most cases of ebonite batteries the battery has a case, which is part of itself, but in the case of these Tudor batteries or of celluloid batteries, it appears that we shall have to have a case apart from the battery box on the board, to facilitate the removal of the battery. These two batteries were sent in charged. Regarding the ampere hour capacities at constant current discharge, we are attaching a table giving a summary of results we have obtained in this direction on which comparative figures may be seen. P. & R.{Sir Henry Royce} BATTERIES X3398 We have already reported on the 60 ampere hour rated capacity P. & R.{Sir Henry Royce} celluloid battery and stated that the ampere hour capacity results did not come out well. We have since that time received a 45 ampere hour P. & R.{Sir Henry Royce} battery made up of ebonite cells placed in a wooden case, and pitched over on to the top Contd. | ||
