Calculating Battery Life
To measure the current draw of a system similar to the one shown below, use Banner cable
BWA-HW-0010.
To measure,
1. Connect the cable to the FlexPower Node and the battery supply module as shown
below. The cable’s male end plugs into the FlexPower Node and the female end
plugs into the battery module.
2. Connect an averaging Fluke meter to the leads. Set the meter to read in amps, not
milliamps.
3. Turn off the Node’s LCD panel by clicking button 2 five times.
4. Allow the meter to measure the operation for at least 10 times the length of the
sample rate.
To estimate the battery life in hours, use the following equation:
Battery life (hours) =
16,000 mA Hr
average current (mA)
To estimate the battery life in years, use the following equation:
Battery life (years ) =
16,000 mA Hr
average current (mA) Ч 8736
