Battery supplied-rate storage fade calculator

Calculate remaining capacity after each bin JSON and remaining capacity with your own figures.

Your numbers

Use the units shown. Results update as you change valid inputs.

Use remaining capacity after each bin JSON and remaining capacity to compare changes to your inputs. The method and limits below explain the scope.

Calculation method

Calculation method

Remaining capacity after each bin (Ah) JSON

Sequential user-supplied linear loss fraction within each time/temperature bin, compounded between bins; no chemistry-specific learned model.

Remaining capacity (%)

Sequential user-supplied linear loss fraction within each time/temperature bin, compounded between bins; no chemistry-specific learned model.

Symbols and units
a
Starting capacity (Ah)
b
Storage time bins (days)
c
User-supplied capacity-loss rates per bin (%/day)

Use the units shown. A list keeps the order in which you enter its values. The symbol ^ means “raised to the power of”.

Assumptions & limits

Assumptions & limits

  • User-supplied measurements and assumptions; Sequential user-supplied linear loss fraction within each time/temperature bin, compounded between bins; no chemistry-specific learned model. Supported limits: Finite numeric values bounded to 1e9 magnitude; lists and tables contain 1–100 records unless a stricter bound is stated. Inputs use the units shown. Lists explicitly paired by a method must have matching lengths; independent polynomial coefficient vectors may differ. Respect stated physical, interpolation, policy and computational domain limits.
