| X.2676. Extract from EFC1/T18.5.20. X.664. BATTERIES. X.2676. LUCAS BATTERIES. We have not been generally impressed with the Lucas batteries. Since previously reporting on these we have received another celluloid Lucas battery (20) which, although doing well on low rate discharge capacity tests, does not show up well on high rate discharge tests. This battery was supposed to have been made to our specification, the terminal being in this instance at the opposite ends of the battery. There are good rubber-covered cable connections from cell to cell which do not heatup appreciably when discharging at a high rate. 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. R.R. 199 (1897) (D&S) 18-7-17) M/ 18805 | ||
