| Contd. -8- EFC1/T18.5.20. batteries tested have seemed to suffer from a similar weakness. It may be expressed that they do not seem to have much life in them. PREMIER BATTERY. This battery (13) was referred to as being disappointing in our EFC2/T7.8.19. The high rate discharge tests were so poor that we have not recorded these. WILLARD BATTERIES. We have recently received from America one Willard battery (30) latest type, with threaded rubber separators. This has shown up quite well on test. The good points about this battery are, large filling holes and good vent plugs which prevent acid spraying during charging. Good cell to cell connecting links and connections for cables. All cells are separate. Owing to the burnt connections, a faulty cell cannot at once be replaced. This battery will be compared with the other more promising batteries for life on the vibration test, a rig for which we have instructed and are awaiting. TUDOR BATTERIES. Further to the remarks contained in our EFC2/T7.8.19, we should say that we obtained excellent results on test from this Tudor battery (12) of 97 1/2 lbs., as will be seen by reference to the table and curves.
