Battery depletion

A battery will be depleted before 2 years when any of these conditions are met:

• Temperature fluctuation: The temperature at the device's location affects the battery. Battery power is used more quickly in a cold environment than in a warm environment. A battery in a device located where the temperature is consistently 20° F will not last as long as a battery in a device located where the temperature is consistently 80° F.

• Scheduling reports: Scheduling more than two reports a day may shorten the battery life to less than 2 years.
