Battery
Battery type
Replaceable 3.6 V LiSOCl (Lithium Thionyl Chloride) single battery (16 Ah)
Note
The battery is not rechargeable; it should be replaced at least every 6 years.
Consumption and battery operation time calculation
Every 5 minutes the advanced power management system of the transmitter calculates the
battery consumption and the remaining battery operation time.
The ambient temperature of the transmitter its also influence the battery capacity.
The typical operation time up to 6 years is based on only 80% battery capacity, low pulse
output frequency, seldom use of communication and 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).
The effect of other temperatures is shown in the figure below.
A variation in temperature from 15 °C to 55 °C (59 °F to 131 °F) reduces the capacity by
17% (in the figure from 15 Ah to 12½ Ah).
