Supercapacitor Discharge Time Calculator

Supercapacitors (EDLCs / ultracapacitors) provide short-term backup power for RTC, microcontrollers, and IoT devices. Calculate discharge time for constant-current or constant-power loads.

Common: 0.1 F, 1 F, 10 F, 100 F
Minimum operating voltage of the load (e.g. RTC ≈ 1.5–2.5 V)
