Hey guys,
I'm working on an Arduino project and trying to calculate the battery life (dissipation) of my power source. I would like to know if there is a calculation to determine the battery life that if possible, also incorporates the operating power variable.
The discharge bar graph listed on the data sheet is from 9 volts 4.8 volts so it doesn't really help as my minimum voltage to power circuit is 7.2V; since power is not dissipated linearly.
I have done testing and gathered the information below. If you need any more information please let me know. I have timed the battery life with a stopwatch and it was approximately two hours.
Details are as follows:
Battery Details
9 Volt Energizer Battery (datasheet attached)
Nominal (full) Voltage of battery = 9.6V
Circuit Details
Continuous current drawn= 128mA
Operating Current Variable (3 second intervals)=336mA
Minimum Voltage (with 9.6V Battery) to operate circuit= 7.2V
Thanks for your help, much appreciated.
