 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 [to match absorption] without worry. Only when you stop cycling the battery do you need to return float voltage to more regular 13.2v 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))
+Watching endAmps at Vabs is an easy way to tell when campervan battery banks are [electrical:12v:charging|fully charged]]. **Deeply cycled banks require long Absorption durations** for current to drop to endAmps.  It is common for misconfigured or poorly designed controllers to "drop to Float" too early, thereby [[electrical:12v:psoc|chronically undercharging]] them and [[electrical:batterycide|shortening their useful lifespans]].
