> 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:// | > If your charge controller only holds [absorption] voltage for an hour or two, that is likely not enough time.
