1. A method for determining a time that a battery can safely be discharged, comprising:
in response to observing that external power has been removed from an information handling system:
powering the information handling system with the battery,
wherein the information handling system comprises:
a frame comprising at least one chassis and the battery, the at least one chassis comprises computing components and an air exchange with heating systems and cooling systems,
wherein the frame is a rack mount enclosure;
wherein the information handling system provides computer implemented services consisting of database services, electronic communication services, and data storage services,
wherein the external power is used as a primary power source for the information handling system,
wherein the battery provides backup power to the information handling system when the external power has been removed;
determining an ambient temperature associated with the information handling system, wherein the ambient temperature is determined by accessing a source, networked to the information handling system, that reports a forecast of ambient temperatures over a predetermined period of time and setting the ambient temperature to an average temperature forecasted for the predetermined period of time;
determining a minimum state of charge for the battery operating at the ambient temperature;
using the minimum state of charge for the battery, determining a maximum time the battery can power the information handling system before discharging below the minimum state of charge; and
initiating shut down of the information handling system when the external power is not restored and a discharge time of the battery equals the maximum time.
