1. What is the IoT Battery Life Calculator?

The IoT Battery Life Calculator estimates how long an IoT device will operate on a single battery charge based on its battery capacity and current consumption.

2. How Does the Calculator Work?

The calculator uses the battery life equation:

\[ \text{Battery Life (h)} = \frac{\text{IoT Capacity (mAh)}}{\text{IoT Consumption (mA)}} \]

Where:

Explanation: The equation calculates how many hours a battery will last by dividing its total capacity by the current draw of the device.

3. Importance of Battery Life Calculation

Details: Accurate battery life estimation is crucial for IoT device design, deployment planning, and maintenance scheduling.

4. Using the Calculator

Tips: Enter battery capacity in mAh and device current consumption in mA. Both values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: How accurate is this calculation?
A: This provides a theoretical maximum. Real-world factors like temperature, battery age, and usage patterns will affect actual battery life.

Q2: What's a typical IoT device current consumption?
A: Consumption varies widely but might range from 0.1mA (deep sleep) to 100+ mA (during transmission) depending on the device.

Q3: Should I use nominal or actual battery capacity?
A: For best results, use actual measured capacity as batteries often deliver less than their nominal rating, especially after aging.

Q4: How does duty cycle affect battery life?
A: If your device has variable consumption, calculate average current consumption including all sleep/active cycles.

Q5: Can I calculate battery life in days or years?
A: Yes, simply convert the hours result to your desired time unit (divide by 24 for days, by 8760 for years).
