How deeply one regularly discharges lead-chemistry batteries will have a **direct effect on how long the battery bank will last**.((Banks are typically replaced when they have lost 20% of their capacity)) | DoD has a **significant impact on longevity of lead deep cycle batteries**.((and, to a lesser degree, lithium batteries)) For this reason [[electrical:inverter|Inverters]] and other high-load devices may have a [[electrical:12v:lvd|low voltage cutoff]] to prevent going below a given SoC, typically 50%. Since this is judged by voltage it is am imperfect science. |

The **most common discharge limit for deep cycle batteries is 50% DoD**. This gives a good balance between usability and longevity. The **lowest cost per Ah** occurs around 30% DoD although this requires buying, installing, and moving //dead lead// or unusable battery capacity.((20% DoD is the limit at which manufacturers rate their battery's cycles.)) | The **most common discharge limit for deep cycle batteries is 50% DoD**.
