How Does Depth of Discharge (DoD) Affect Battery Cycle Life?
Lead-Acid Batteries. Lead-acid batteries, a traditional choice for many applications, exhibit notable sensitivity to depth of discharge. Typically, these batteries have a recommended DoD range of about 50% to 80%. Discharging a lead-acid battery beyond this range can lead to accelerated degradation and a reduced number of charge-discharge

In practice, the relationship between battery capacity and discharge current is not linear, and less energy is recovered at faster discharge rates. During discharge, ohmic losses in electrolyte and contacts lower voltage. Internal impedance increases due to lowering electrolyte concentration and electrode sulfation.

Battery Charging and Discharging Parameters
This occurs since, particularly for lead acid batteries, extracting the full battery capacity from the battery dramatically reduced battery lifetime. The depth of discharge (DOD) is the fraction of battery capacity that can be used from the battery and will be specified by the manufacturer. For example, a battery 500 Ah with a DOD of 20% can only provide 500Ah x .2 = 100 Ah.

Battery Depth of Discharge (DoD) and overall battery life
Lead acid batteries have a DoD range of approximately 50% to 80%. This means that, for optimal lifespan and performance, it''s recommended to avoid discharging them below 50% of their total capacity. Going below this threshold can lead to accelerated degradation and a reduced number of charge-discharge cycles.
