 Some controllers will allow the user to configure the time or ratio of capacity/current (C///n//).  Sternwake says:
 > If your charge controller only holds [absorption] voltage for an hour or two, that is likely not enough time. As long as [there is a load] and you cycle the battery daily, you could set float voltage to 14.8v((for example - secessus)) [to match absorption] without worry. Only when you stop cycling the battery do you need to return float voltage to more regular 13.2v((for example - secessus)) levels. Premature application of float voltage by automatic charging sources is a battery killer.((http://www.cheaprvliving.com/forums/Thread-Solar-or-Battery-Problem?pid=229883#pid229883))
+If Absorption cannot be completed in the max amount of time configurable in the controller (due to damaged/old batteries), **charging at the minimum rate and/or at higher voltage may help [[electrical:severe_battery_use|compensate]]**.
