One set has had about 2 grid outages in 9 years, the other maybe 9 grid outages. From my experiance the sealed AGM should be the battery of choice for long float periods. </span></div><div><span>Darryl. </span></div><div><br></div> <div style="font-family: arial, helvetica, sans-serif; font-size: 12pt;"> <div style="font-family: times new roman, new york, times, serif; font-size: 12pt;"> <div dir="ltr"> <font size="2" face="Arial"> <div style="margin: 5px 0px; padding: 0px; border: 1px solid rgb(204, 204,

<div id="yiv1829325013"><font size="4" face="arial"><div style="margin: 0px; padding: 0px;">my inquiry is about the health of floating a lead antimony battery bank, in a grid-tie with battery back-up system, where the batteries float 99% of the time... considering (not specifically about any particular brand/manufacturer) i have also heard talk about the necessity to have to "work harden" a set of deep cycle batteries to get optimal use and capacity.</div>
<div style="margin: 0px; padding: 0px;"> </div>
<div style="margin: 0px; padding: 0px;">in a battery backup system, the batteries wear our from old age, rather than cycling lifespan. it is common for batteries in these systems to go years with no cycling. if cycling is healthy for a battery. i'd like to know that. i have heard people speculate on it before, but never got a definitive answer from a manufacturer. i respect jamie and his expertise, so that is why i'd like to hear what he has to say about these batteries theories floating out there in wrench land.</div>
