    What Is Battery DOD (Depth of Discharge)?

    Jan , 17 2026
    Depth of Discharge (DOD) refers to the percentage of a battery’s rated capacity that has been discharged during a single cycle. Formula:DOD = (Discharged Capacity / Rated Battery Capacity) × 100% Examples: A 100 Ah LiFePO₄ battery that delivers 30 Ah has a DOD of 30%. If the battery is discharged until only 20% state of charge (SOC) remains, the DOD is 80%. DOD = 100% represents a full...
