You can discharge a deep cycle battery to a maximum of 80% Depth of Discharge (DOD), but it's recommended to discharge it to no lower than 50% DOD.
Understanding Depth of Discharge (DOD)
Depth of Discharge (DOD) refers to the percentage of battery capacity that has been discharged. A 0% DOD means the battery is fully charged, while a 100% DOD means the battery is completely discharged.
Recommended Discharge Levels for Deep Cycle Batteries
| Discharge Level | DOD (%) | Impact |
|---|---|---|
| Recommended Minimum | 50% | Optimal lifespan and performance. |
| Maximum Safe Level | 80% | Absolute maximum discharge to preserve battery life, avoid exceeding this. |
Key Takeaway: To maximize the lifespan of your deep cycle battery, it is generally best practice to avoid discharging it below 50% DOD. Occasional discharges to 80% DOD can be tolerated, but frequent deep discharges will significantly reduce the battery's overall life.
