Oregon Method Equation:
From: | To: |
The Oregon method provides a simple way to estimate battery life by dividing the battery capacity by the current draw. This gives the theoretical maximum runtime in hours.
The calculator uses the Oregon method equation:
Where:
Explanation: The equation calculates how many hours a battery can theoretically last by dividing its total capacity by the current being drawn.
Details: Accurate battery life estimation helps in designing electronic systems, planning battery replacements, and optimizing power consumption.
Tips: Enter battery capacity in mAh and current draw in mA. Both values must be positive numbers.
Q1: How accurate is the Oregon method?
A: It provides theoretical maximum runtime. Real-world results may be 10-30% less due to factors like temperature and battery age.
Q2: What's a typical battery capacity?
A: Common capacities range from 200mAh (small coin cells) to 3000mAh (smartphone batteries) to 10000mAh (power banks).
Q3: What affects current draw?
A: Device power requirements, usage patterns, and efficiency all impact current draw.
Q4: Can I use this for any battery type?
A: Yes, but remember different chemistries (Li-ion, NiMH, Alkaline) have different discharge characteristics.
Q5: How can I extend battery life?
A: Use higher capacity batteries, reduce current draw through optimization, or implement power-saving modes.
