The absorption phase of a charge controller can be set to hold the battery bank at a steady voltage for a set duration of time. A sufficiently long absorption phase is desirable as it ensures that the battery receives a full charge under substantial current, which is helpful to ensuring a long cycle life. The appropriate duration of an absorption charge depends upon the battery type, the size of the battery bank, and the maximum available charge rate for the system. A manufacturer may give a recommendation in the manual for the particular battery, but often times other sources must be consulted.
