I am convinced that cycling batteries need to be cycled <span style="mso-spacerun: yes;"> </span>and equalized. Here is my understanding or
guess. A cycling battery stratifies much faster than a lead calcium (float battery).
The stratification is because of self-discharge and the water rises to the top
and acid concentrates on bottom.<span style="mso-spacerun: yes;"> </span>When the
low concentration acid near the top causes plate corrosion and swelling of the plates
and fixing of the lead sulfate.<span style="mso-spacerun: yes;"> </span>If the
battery is to float a long time a good AGM type may be better.<span style="mso-spacerun: yes;"> </span>However remember some batteries do not like
vibration.<span style="mso-spacerun: yes;"> </span><?xml:namespace prefix = o ns = "urn:schemas-microsoft-com:office:office" /><o:p></o:p></span></div><div><font face="Times New Roman">

<div id="yiv1978814204SafeStyles1329336257">I would not recommend using an RE battery for standby/back up use.
<div>There is a similar problem that I have seen. People use 6 volt golf cart batteries in their motorthome and then stay plugged into shore power for long periods of time. I see premature failures from this type of use. A golf cart battery is designed to be cycled, not left in float service. Without exercising the battery by occasionally discharging it and then charging and equalizing, it is likely to fail early. My opinion is anecdotal but I'm convinced it is true.
