The battery lifetime of course depend on how often the unit transmits, and the size of the battery. The RC16xxxx-SIG module provides a very low sleep current, so if the number of transmissions are limited, the battery lifetime can be very long. If the unit is used to transmit very seldom alarms, and only a daily keep-alive message is transmitted and receiving one command message per day, the battery lifetime can be more than 10 years using a 3.6V lithium AA-cell battery. Another example, the lifetime is 6 years using a 3.6V lithium AA-cell battery transmitting 10 times per day. This is a conservative figure as the battery capacity is de-rated to 60% due to the pulsed current consumption.
