Super capacitor discharge time calculator. This calculator determines timekeeping operation using a supercapacitor (ultracap) based upon starting and ending capacitor voltages, discharge current, and capacitor size. Formulas used: Bt(seconds) = [C(Vcapmax – Vcapmin)/Imax]  This formula is valid for constant current only. Bt(seconds) = -log(Vcapmin/Vcapmax)(RC) = t  This formula is valid for linear current only (simple resistive load). Edit the input …
