| EFCL/T26.2.27. It is now extremely improbable that any alternative 12-volt batteries of the same size and weight can put up a better all round performance than is now shewn by our own standard battery. At any rate, it is a fact that we have not obtained anything like the performance from various batteries of other makes which we have in the past been tested. It is satisfactory to note that there is very little to choose between our two standards, and that it would be very difficult to come to a conclusion that one was definitely better than the other. In due course it will no doubt be of interest for a similar report in connection with the 20 HP. batteries to be circulated. EFC. {E.
