Abstract : On the basis of a comparitive evaluation of the low temperature performance of batteries, the properties of available insulating materials, estimates of the weight, cost, and volume of various auxiliary heating devices, and experimental studies of the cool-down rates of insulated battery systems, the following conclusions have been reached: (1) present batteries are serviceable in conditions of extreme cold for very short mission lives or very low current drains; (2) for missions a few hours in length, inexpensively insulated conventional batteries should be serviceable; (3) for somewhat longer missions, auxiliary heat or superinsulation is required; and (4) for long missions (in excess of 8 hours) auxiliary heat, preferably in conjunction with inexpensive insulation, is necessary.
