Every 5 minutes the advanced power management system of the transmitter calculates the
battery consumption and the remaining battery operation time.
For battery versions, only the internal battery pack has a nominal capacity of 34 Ah giving a
typical operation time up to 6 years in a revenue application.
The ambient temperature of the transmitter also influences 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).

Note
The installation orientation of the battery pack may influence the battery capacity. Optimal
battery capacity is achieved with the battery pack in an upright position.
