Formula and assumptions
hours = (Ah × Vbattery × usable fraction × efficiency) / (Vload × Aload)Constant average load at its stated voltage. Capacity is rated at the battery voltage. For no regulator, use the same input/load voltage and 100% efficiency. This is an energy estimate, not a guarantee: temperature, aging, cutoff voltage, peak loads and discharge rate matter.
