Per IEEE Standard 485, if the operating temperature of a battery (Lead Acid) is different from
that of the library curves used, the temperature correction factor should be applied in calculation

different operating temperature values, between –3.9 °C and 51.7 °C, assuming that the battery
characteristic curves are given at 25 °C.
etap Battery Sizing program determines the temperature correction factor according to this
table.

modified by adding 10 °C. Therefore, the correction factor at 35 °C is equal to 1 and the
