| Contd. -3- EFC1/T11.10.24. Accu-Slem Battery. We have had several of these batteries and with the exception of cells which we have specially opened up for examination, practically all are still working satisfactorily. Originally on 25.11.21 we received from our Paris Depot one battery of this type on account of the satisfactory results which they stated they had been having with these batteries as compared with the standard 40/50 6BXE5, previous to modifications. They also stated that they did not suffer from the same faults of buckling and short circuits. It appeared that they had had these batteries made up (by a French firm) of dimensions similar to the Exide and had used a number of them on cars which came to their depot. Previous to putting the battery on test, a cell was opened up and it was decided that the construction was exactly similar to the Exide cell as it then was (previous to improvements) and there did not seem any reason why the battery should be in any way superior, though there was a feeling that the paste might be harder. The battery was put through our routine tests and did particularly well as compared with the standard Exide, both on the high rate and low rate discharge tests. Then, on 8.1.23, the battery was put on a School car 29-CB and remained on till 23.10.23 when it had completed a total mileage of 23,000. It gave no trouble and only required about half a pint of water per week. Contd. | ||
