    Per IEEE Standard 485, if the operating temperature of a battery (Lead Acid) is different from- ^& B! t  k- ?; w+ Y
    that of the library curves used, the temperature correction factor should be applied in calculation3 t. d# w- D! H* x: y
    of battery capacity. Table 1 of the IEEE Standard 485 gives a list of correction factors for
    ) {: _$ |7 a: S7 w# V) S. v$ A( Udifferent operating temperature values, between –3.9 °C and 51.7 °C, assuming that the battery8 O8 |* J  x1 A7 V) n# w: B
    characteristic curves are given at 25 °C.% [7 c/ J9 S7 B1 k
    etap Battery Sizing program determines the temperature correction factor according to this

    1. If the battery characteristic curves used in the calculation are for 25 °C and the battery

    by the interpolation method based on the values given in table.; L% E4 G: M& |3 i; X- b9 R+ j
    2. If the battery characteristic curves used in the calculation are for 25 °C, but the battery
