Calculate battery runtime, required capacity, and power consumption with precision. Supports multiple battery types, temperature compensation, aging factors, and comprehensive unit conversions for professional and hobbyist applications.
Add multiple devices to calculate total power consumption. Use the Manual Entry tab for custom devices, or the Device Library tab to quickly select from common components like Arduino boards, sensors, LEDs, and motors with pre-defined power consumption values. Perfect for projects with multiple components.
Runtime Mode: Enter your battery capacity and load to calculate how long your battery will last.
Capacity Mode: Enter desired runtime and load to find the minimum battery capacity needed.
Power Mode: Enter battery capacity and desired runtime to find maximum allowable power consumption.
Device Library: Use the device library to quickly add common components like Arduino boards, sensors, and LEDs with pre-defined power consumption values.
Advanced Features: Use temperature compensation, aging factors, multi-cell configurations, and safety margins for professional applications. The calculator accounts for real-world conditions including temperature effects, battery degradation, and discharge characteristics.
Data Source: Battery specifications and device power consumption values are loaded from the battery_data.psv file for easy maintenance and updates.
