The above estimates assume no fan, but a passive heat sinking arrangement. Estimated RTC
battery life (as opposed to battery failures) is not accounted for in the above figure and
needs to be considered separately. Battery life depends on both temperature and operating
conditions. When the Kontron unit has external power, the only battery drain is from leakage
paths.
