I am doing some calculations to determine battery life under certain load conditions. As such I have turned to the internet and found this online calculator by DigiKey. The calculator used the following equation:
Battery Life = Battery Capacity in Milli amps per hour / Load Current in Mill amps * 0.70
My question is:
- What is the 0.7 scalar multiple on the equation for?
- how can i take into consideration battery internal leakage current into my calculation?
