Hi all,
I'm trying to figure out my power consumption so that I can estimate run time for a given battery. Normally this would be pretty straight forward - I'd get a crude estimate by dividing AH by current. However, the current is only a few times per day, as follows:
Current draw:
220 mA for 30 seconds per day.
35 mA for 2 minutes per day.
3.5 mA for 12 hours per day.
20 mA for 12 hours per day.
Battery: 12V, 9AH SLA.
Can someone help untangle my brain to see the obvious thing that I'm missing?
Thanks,
Jack
