A deep cycle battery is designed to provide sustained power over extended periods and can be discharged up to 80% of its capacity repeatedly without damage. Unlike automotive starter batteries (which deliver short, high-current bursts for engine ignition), deep cycle batteries prioritize deep discharges and recharges. They feature thicker plates and denser active material to withstand cycling stress, making them ideal for renewable energy, marine, RV, and industrial applications.
Recharge immediately after use to avoid prolonged states of partial or full discharge. Do not regularly discharge below 50% Depth of Discharge (DoD) for lead-acid types or 80% for LiFePO4 batteries. For optimal longevity, recharge when the battery reaches 50% capacity (lead-acid) or 20% (LiFePO4). Avoid storing the battery in a discharged state, as sulfation (lead-acid) or cell degradation (lithium) can occur.
Lifespan depends on chemistry, usage, and maintenance:
Flooded Lead-Acid: 3–7 years (with regular watering and equalization).
AGM/Gel: 4–8 years (maintenance-free but sensitive to overcharging).
LiFePO4: 10–15 years (2,000+ cycles at 80% DoD; minimal maintenance).
Factors like depth of discharge, temperature, and charging practices significantly impact longevity.
