What is a Battery Life Calculator?

A Battery Life Calculator is a tool that estimates how long a battery will last based on its capacity (mAh or Ah) and the device’s power consumption (mA or W).

Why Use a Battery Life Calculator?

  • To estimate battery runtime before using a device.
  • For designing power-efficient electronics like IoT devices, drones, or electric vehicles.
  • To plan battery replacements in UPS systems, solar power setups, or smartphones.

How Does a Battery Life Calculator Work?

  1. Takes Inputs:
    • Battery Capacity (mAh or Ah)
    • Device Power Consumption (mA or W)
    • Voltage (if needed)
  2. Applies the Formula:
    • If using watts, the formula adjusts based on voltage.
  3. Outputs Estimated Battery Life in hours or days.

When to Use a Battery Life Calculator?

  • Before buying or designing battery-powered devices.
  • For optimizing energy consumption in mobile devices and wearables.
  • To ensure reliable battery backup in critical systems like medical devices.
