A full cycle is defined as: Discharge to programmed DOD, and charge back to 100%. Partial cycles occur when the battery is not discharged completely to it’s programmed DOD setting before it’s fully recharged. With respect to the warranty, this means cumulative cycles totaling the rated DoD settings (per the warranty) are the equivalent of a cycle.
