How do I calculate how long a battery operated product will run?
Here's what I've got:
- 2 AA, 1.5V, 2700mAH batteries
- Voltage Regulator with a Iq of 25 uA
- Voltage Regulator Eff = 80%
- Active Current = 50mA
- Sleep Current = 1uA
- Duty Cycle = 99.9% (only active 0.1% of the time)
- Active Voltage is 3.3V
I've gone the current route and got an answer. I went the power route and got a TOTALLY different answer (days vs years different).
How do you do this?
