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
of battery capacity. Table 1 of the IEEE Standard 485 gives a list of correction factors for
" @  G; O  F" z+ c& H, edifferent 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

operating temperature is between –3.9 °C and 51.7 °C, the correction factor is determined
by the interpolation method based on the values given in table.

factor given in Table 1 are shifted and then used as described in the above. For example, if

modified by adding 10 °C. Therefore, the correction factor at 35 °C is equal to 1 and the
operating temperature range becomes 6.19 °C and 61.7 °C.
