Different battery chemistries have different discharge signatures, which can affect the accuracy of voltage-based SoC methods. To get accurate readings, the battery needs to rest in the open circuit state for at least four hours, although battery manufacturers recommend 24 hours for lead acid batteries.
The proposed method focuses on the factors that determine quality of remaining useful capacity to counter hysteresis of variables of lead–acid batteries and judge battery failure at the end of service-life. Lithium battery degradation prediction has received wide interest in battery management systems.

You can calculate the run-time using the formula, t = (amp-hour × V)/P, where amp-hour is the battery's maximum capacity, V is the voltage of the power supply, and P is the appliance's wattage. In the US, the household power supply's voltage is 120 V. Therefore, a 100 Ah battery can supply power for 12 hours in the US for a 1000W-appliance.
