Battery Life Calculator: Estimate Device Runtime

Calculate Your Battery's Estimated Runtime

Understanding your device's battery life is crucial for planning. Our Battery Life Calculator helps you accurately estimate how long your battery will last based on its capacity, voltage, and the average current draw of your device. Perfect for DIY electronics, remote sensors, and portable gadgets, ensuring you never run out of power unexpectedly.

Formula:

Battery Life (Hours) = Battery Capacity (mAh) / Average Current Draw (mA)
Where:

  • Battery Capacity (mAh): Milliampere-hour rating of the battery
  • Average Current Draw (mA): The average current consumed by the device in milliamperes
