2.2.11 Battery Life
Below are typical battery life times for the different operating modes of
the TX20K. The 2 batteries listed are an Ultralife 9V Lithium battery and
a standard 9V Alkaline battery. The battery capacities used for the
calculations are 1200mAh for the lithium and 550mAh for the alkaline.
These values are with a 350
Ω gage connected and at and RF Power
level of 1. Actual battery life times can vary depending on battery type,
age, charge state, RF power level, gage resistance and operating
environment.
