Battery Life Estimates
The following table provides the battery lifespan indicated for two SAFT LSH14 batteries
lifetime estimates are based on distance measurements in the range 10 to 20 m and a
model following a Barcelona temperature profile. Bear in mind that consumption varies
depending on the sampling rate and environmental conditions.
Note: European radios work between SF7 and SF11, and FCC radios work between SF7 and
SF9.
