As a simple rule, to calculate how long a 12v deep-cycle battery will last with an inverter multiply battery amp-hours (Ah) by 12 to find watt-hours, and divide by the load watts to find run time hours. Finally, multiply run time hours by 95% to account for inverter losses. Introduction to Solar. . 12V Battery Runtime Calculator estimates how long a battery will last under a specific load. By entering the battery capacity and the device's power consumption, you can efficiently plan your usage and avoid unexpected power failures. A larger 20kWh+ system (common in home energy. . Materials break down slowly. Say, until 80% original capacity. For example, 500 cycles means it hits 80% after 500 rounds. Charge from panels day, discharge night.
