Typical operation time of 7 years is based on an operation time/temperature profile of 5% at 0
°C (32 °F), 80% at 15 °C (59 °F) and 15% at 50 °C (122 °F), 0.1 % at menu 3 operation and
0.1 % at IrDA operation, and no use of add-on communication module.
Leakage detection (advanced version only) will affect battery operation time if a higher
excitation frequency is selected during leakage period.
