Evaluation of Cranking Characteristics of Commercially Available Batteries between Room Temperature and -40 C

摘要

The cranking characteristics of three brands of commericially available batteries (GROUP 24) were measured between room temperature (RT) and -40 C. They were fully recharged at RT before each discharge which was carried out at constant current corresponding to the 3C to 4C rates. Under the same experimental conditions, the behaviour on discharge of these batteries was found to be very similar. The only significant differences observed concerned the increase in internal battery temperature resulting from a discharge. (Author)
