As the battery becomes fuller - at around 80% of full charge - the charge controller switches to absorption mode at which point it attempts to hold the battery bank at the maximum voltage achieved during the bulk charging phase (~14.4-14.8V for a 12V lead acid battery) using the minimum amount of current necessary to do so. The amount of current required to hold it at the fixed voltage decreases. The charge controller will continue in this mode until either a set amount of time has passed, or the amount of current required to hold the battery bank at a fixed voltage decreases to a programmed minimum. This typically occurs at around 95% of battery capacity.
