The invention provides an insulated container having a temperature monitoring device that can be used to maintain an object stored in the container at a temperature that is below the normal operating temperature of the temperature monitoring device while still permitting the taking of measurements of the interior of the container. The container includes an RF transponder having an RF antenna, a temperature sensor, and a battery that is operatively connected to the transponder and the temperature sensor. The temperature sensor is positioned in the container so that it is in a temperature monitoring relationship with the interior space of the container. The battery is positioned at least partially in one of the walls of the container at a location that is spaced apart from the temperature sensor and that is selected so that the battery does not experience a temperature that is below an operating temperature of the battery.
