Battery Life Equation:
From: | To: |
The battery life equation estimates how long a battery will last based on its capacity and the current draw of the device. It's essential for planning power usage in electronic devices.
The calculator uses the battery life equation:
Where:
Explanation: The equation calculates how many hours the battery will last by dividing its total capacity by the current consumption rate.
Details: Accurate battery life estimation is crucial for device usage planning, especially for solar-powered or portable devices where power management is critical.
Tips: Enter battery capacity in mAh and current draw in mA. Both values must be positive numbers.
Q1: What affects battery life in real-world usage?
A: Temperature, battery age, discharge rate, and other factors can affect actual battery life compared to theoretical calculations.
Q2: How accurate is this calculation?
A: It provides a theoretical maximum. Real-world results may be 10-25% lower due to various factors.
Q3: Can I use this for any battery type?
A: This calculation works for most battery types (Li-ion, NiMH, etc.) when using their rated capacity.
Q4: What if my device has variable current draw?
A: Use the average current draw for estimation, or calculate for different usage scenarios.
Q5: How does solar charging affect the calculation?
A: Solar charging extends battery life by adding energy. The calculation would need to account for both consumption and charging rates.
