Question 1

How accurate is the battery runtime calculation?

Accepted Answer

Our calculator provides professional-grade estimates by accounting for discharge curves, temperature effects, self-discharge, protection circuit losses, and DC converter efficiency. Actual runtime may vary by ±10-15% depending on real-world conditions and battery age.

Question 2

What battery chemistries are supported?

Accepted Answer

The calculator supports Li-Ion, LiFePO4, Lead-Acid, NiMH, and Alkaline batteries. Each chemistry has specific discharge characteristics, voltage curves, and temperature coefficients for accurate modeling.

Question 3

How do load profiles affect battery runtime?

Accepted Answer

Different loads drain batteries at different rates. Our calculator allows you to define multiple load profiles with varying currents, voltages, durations, and duty cycles to accurately model real-world usage patterns like sleep modes, active operation, and peak loads.

Question 4

Why does temperature matter for battery runtime?

Accepted Answer

Battery capacity decreases at low temperatures and increases slightly at high temperatures. Our calculator models these effects - a battery at -20°C may deliver only 60-70% of its rated capacity compared to 25°C operation.
