All cells are separate and held together only by the connecting links and a sort of celluloid tray with handles for lifting and carrying the battery, which we do not consider at all a good feature, as it strikes us as being unsafe. The terminals are very well protected from corrosion by rubber and lead; vent plugs not good. It is possible that this battery might have a good life. MULTIPLE STORAGE BATTERIES. We have received from America a sample Multiple Storage battery which appears from all accounts to be very good. We have not so far done any tests on this, but shall be starting these immediately now. Ni-Fe BATTERIES. We have arranged with Batteries Ltd., Redditch, to send us on loan an Ni-Fe Alkaline battery for us to test and let them have the results, but this battery has not so far arrived. P & R BATTERIES. We have previously reported that we have not had good results from these. The last one received (14) was described in our EFC {E. Fowler Clarke - Electrical Engineer} 2/T7.8.19, and the results from this battery, especially the high rate discharges, have been very disappointing.
