Calculation method

Calculation method

Remaining throughput (MWh)

Subtract recorded usage from supplied warranty limits; does not determine contractual claim entitlement.

Remaining cycles (count)

Subtract recorded usage from supplied warranty limits; does not determine contractual claim entitlement.

Remaining calendar years

Subtract recorded usage from supplied warranty limits; does not determine contractual claim entitlement.

Any entered limit reached

Subtract recorded usage from supplied warranty limits; does not determine contractual claim entitlement.

Symbols and units
a
Recorded discharge throughput (MWh)
b
Warranty discharge-throughput limit (MWh)
c
Recorded cycles (count)
d
Warranty cycle limit (count)
e
Age (years)
f
Warranty calendar limit (years)

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; Subtract recorded usage from supplied warranty limits; does not determine contractual claim entitlement. 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.
