Meter Battery Considerations
The meter’s battery life expectancy depends on both temperature and the
amount of time the meter is without power. For typical installations, the
battery should last 10 years minimum at 25ºC meter ambient operating
temperature. The battery is field replaceable (see “Replacing the Battery” on
page 31).
