What is Depth of Discharge? Everything You Need to Know

With each utilization of the battery, a proportion of this ''water''—or, more accurately, stored electrical energy—is depleted. The Depth of Discharge provides a metric, denoting the percentage of energy that has been drained from the battery. A higher DoD percentage indicates a more substantial depletion of the battery''s total capacity.

What is Depth of Discharge and Why It''s important?

Depth of discharge (DOD) refers to the amount of a battery''s capacity that has been used up or discharged. It is typically expressed as a percentage of the total capacity of the battery. For example, if a battery has a capacity of 100 Ah (amp-hours) and has been discharged by 80 Ah, its DOD would be 80%.
