Battery Life Estimator

Estimate battery runtime based on capacity and load current with optional Peukert's Law compensation.

Battery & Load

Battery Capacity (mAh)

Average Load Current (mA)

Safety Margin (%)

Recommended: 20% to avoid deep discharge.

Enable Peukert's Law

Standard calculation:

\text{T}=\frac{\text{Capacity}}{\text{Current}}

Peukert's Law accounts for the fact that battery capacity decreases as the rate of discharge increases.
