Ideal battery runtime estimate

Estimate runtime from usable battery energy and a constant average load.

Published · R0

Method and scope

Ideal runtime in hours = usable battery energy in watt-hours ÷ average load in watts.

Calculate an ideal energy-over-power runtime estimate for learning or rough comparison. Intended for Learners, General users.

Inputs

SOURCE AND LIMITS

Assumptions: Battery energy is usable energy at the system output. The load is constant at the entered average power.

Limitations: Nameplate capacity may differ from usable energy at the output.
