RV battery runtime calculator

Convert amp-hours to watt-hours and account for usable depth of discharge and inverter losses.

Estimated runtime8.6 hours

Nominal energy: 2400 Wh
Usable AC energy: 1728 Wh

Planning estimate only. Actual weather, shade, battery condition, driving, fuel prices and trip costs can change results.

Battery runtime assumptions

Nominal watt-hours equal volts × amp-hours. Usable AC energy applies your depth-of-discharge limit and inverter efficiency before dividing by device watts.
