Usable capacity

100% of this battery’s nominal capacity is usable, 13.5 kWh in the scored configuration.

13.5 kWh usableScored configuration: Powerwall 3.

No reserve is withheld at the stated depth of discharge.

At a sourced 100% depth of discharge the usable and nominal figures are the same number, so no separate nominal capacity is stated.
